Best Authenticator App: 6 Ranked by Backup Safety [2026]

Pick the wrong authenticator app and you find out on the worst possible day: the day your phone dies, gets stolen, or falls in a lake. The best authenticator app in 2026 is not the one with the nicest code screen. It is the one that lets you buy a new phone and get every login back in a single sitting.

That backup question is driving most of this autumn’s product news. Microsoft began rolling out a refreshed Authenticator interface on iOS in October 2026, according to heise online, with Android reportedly scheduled for November. 2FAS shipped version 6.0.1 for iOS, with a redesigned interface and extra importers. Ente Auth has reportedly also improved its import tools. Everyone is polishing the same weak spot, which is how you move codes between phones.

This ranking compares six apps that people actually search for: 2FAS Authenticator, Aegis Authenticator, Microsoft Authenticator, Ente Auth, Google Authenticator and Authy. We rank them on backup safety first, then account requirements, platform reach, maintenance record and price. If you only want a head-to-head of the three big-brand apps, our earlier comparison of Google Authenticator, Microsoft Authenticator and Authy covers that ground. This piece widens the field to the open-source apps that now set the pace.

Best Authenticator App in 2026: The Quick Picks

Short on time? Here is the ranking in one table. The order reflects how safely each app lets you survive a lost phone, with a tiebreak on how long the project has stayed actively maintained. Every app on the list was still active on October 23, 2026, and none had been renamed, sold or retired according to the sources we checked.

RankAppBest forMain caveat
12FAS AuthenticatorMost people on Android or iPhone who want no account and no adsYou must set up encrypted backups yourself before you need them
2Aegis AuthenticatorAndroid users who want full control of an encrypted vaultAndroid only, so iPhone owners need a different app
3Microsoft AuthenticatorAnyone signing in to Microsoft work, school or personal accountsNo longer a place to keep passwords
4Ente AuthPeople who want synced, encrypted codes across devicesSeveral details rest on a single source, so confirm on Ente’s site
5Google AuthenticatorPeople who live inside a Google Account and want the simplest setupCheck that sync is on before you rely on it
6AuthyExisting users who already have it configuredDesktop apps are gone and Twilio is steering developers elsewhere

Rank 6 does not mean Authy is broken. It means that if you were starting fresh today, five other apps give you clearer control over your own data. We explain each placement below, then close with a migration guide for anyone switching.

How This Authenticator App Ranking Works

One thing up front: no lab publishes standardized benchmark scores for authenticator apps. All six generate the same kind of time-based one-time password, and a six-digit code is a six-digit code. So you will not find fake “speed tests” here. The ranking rests on documented features, release records, vendor pages fetched on October 23, 2026, and independent reviews, plus a few industry data points covered in the benchmarks section.

We weighted five criteria. Backup and recovery counts for the most, because losing a phone without a backup is the number one way people get locked out. Account requirements come second, since an app that works with no sign-up has fewer ways to fail. Platform reach, maintenance record and price round it out. Where a fact appeared in only one source, we say so in the text and keep it out of the tables.

What counts as a good backup

A good backup is encrypted, restorable on a different phone, and under your control. Encrypted means a thief who grabs the file cannot read your codes. Restorable means you have actually tried it, not just ticked a box in settings. Under your control means you can export or move the data without begging a support desk. Apps that meet all three rank high. Apps that depend on a single vendor account rank lower, though that trade can still be fine for people who already trust that vendor.

What we did not score

We did not score the visual design, because that is personal taste, and we did not score password-manager features. A few apps in this field double as password managers or sit next to one, and that is a different buying decision. We also left out the bundled authenticators inside password managers, apart from a short note on Bitwarden’s pricing, since they deserve their own ranking.

Authenticator App Specs Comparison Table

The table below puts the six apps side by side on twelve rows. Cells that say “See text” mark facts that appeared in only one source. Each of those is hedged in the matching app section instead of stated flatly here. “Not stated” means the sources we checked did not say, which is different from “no”.

Two rows deserve a closer look. First, the “Account to use the app” row separates the apps that work out of the box (2FAS and Aegis) from those where an account enters the picture the moment you want sync. Second, the “Separate password manager” row carries a warning for Microsoft users: the vendor removed password storage and autofill from Authenticator in mid-2025, according to two independent reviews, so any older guide that tells you to keep passwords there is out of date.

Authenticator App Pricing in October 2026

Authenticator apps are a rare corner of software where free is the norm. The table lists what the sources we verified say about each price. For apps where the free status rests on a single source, the paragraph after the table gives the hedged version.

AppPrice in October 2026Paid extrasBasis
2FAS AuthenticatorFree, no subscription, no ads2FAS Pass password manager sold separately2FAS pricing page and third-party reviews
Aegis AuthenticatorFree, open source under the GPLNone, no paid tierProject listing and release page

AuthyNo consumer price in verified sourcesDeveloper API closed to new customersTwilio documentation
Bitwarden Premium (for comparison)$19.80 per year, reportedly up from $10Not applicableToolBistro and Authenticator.sh

Twilio’s documentation describes Authy as a free app for generating one-time codes, and third-party reviews describe Google Authenticator and Ente Auth as free, though none of those pages is a formal price list. The practical takeaway: you should not need to pay anyone to generate codes. If an app asks for a subscription just to show you a six-digit number, walk away. The only money question worth asking is whether you want a password manager alongside, and for that Bitwarden’s Premium plan is a useful yardstick at a reported $19.80 per year.

Note that “free” does not mean “no cost.” Some apps pay for themselves with your data or your attention. Our two open-source picks avoid that trade by design, since their code is public and neither requires an account. For Microsoft and Google, the price is that you tie more of your digital life to one vendor. That may be a fair deal for you. It just belongs in the ledger.

The Open-Source Leaders: 2FAS and Aegis

The top two spots go to apps that treat your codes as your property. Neither needs an account, both are free, and both are in active development as of this week. They differ mainly on platform: 2FAS covers Android and iOS, while Aegis is Android only.

2FAS Authenticator: best all-round pick

2FAS earns first place because it removes the two biggest sources of friction at once. The app works without an account, and its own site pitches 100 percent anonymous use. It also carries no ads and no subscription, per its pricing page and several third-party reviews. Backups are encrypted and can go to your own cloud storage, and you can export tokens manually if you want a file you control.

The release cadence is healthy. The iOS app reached version 6.0.1, with a redesigned interface, additional importers, larger cells, auto-detection controls and bug fixes. On Android, reports point to a 6.0 cycle that began in September, with 6.0.5 listed as the newest build. Treat that Android build number as reported rather than confirmed, since it comes from a single source.

One thing to keep straight: 2FAS Pass is a separate password manager and not part of the authenticator. Its subscription pricing lives on the 2FAS pricing page, and it should not color how you judge the free authenticator. The company behind both is Two Factor Authentication Service, Inc., and nothing in the sources we checked suggests an acquisition, rename or shutdown.

The weakness is the usual one for any app that leaves backup in your hands. Nothing forces you to turn encrypted backup on, so the safety you get depends on a ten-minute habit. Do it on day one.

Aegis Authenticator: best for Android power users

Aegis is the app security people recommend when the question is “who do I trust with this vault?” The project is free, open source under the GPL, has no accounts and has no paid tier. Its latest release in our sources is v3.4.3, published September 6, 2026, and a third-party listing on wares.gg reports that the latest release and the most recent commit share that date, a sign of active upkeep.

That release matters for two reasons. It added support for importing encrypted Proton Authenticator exports, which widens the exit door for people leaving Proton’s app. It also fixed a security issue in which a malicious icon pack could overwrite internal Aegis files, potentially including the vault file. The fix is a good example of why we like open projects: the bug and its repair are public, so you can read what happened instead of trusting a press line.

The catch is simple. Aegis runs on Android only. If your household mixes Android and iPhone, you will want a second app for the iPhone users or you will want 2FAS for everyone. Aegis also expects you to manage your own backup file, so pair it with a habit of copying the encrypted export somewhere safe after each new account you add.

Microsoft Authenticator: Best for Work and School Accounts

Microsoft Authenticator holds third place, and for a large group of readers it is the right answer regardless of rank. If your employer or university runs on Microsoft sign-in, this is the app the admin console expects. Microsoft’s own documentation presents it as an active app for iOS and Android that handles two-factor verification, phone sign-in and code generation for personal, work or school, and third-party accounts. It also supports passwordless sign-in and passkeys, which the other apps in this ranking do not list in the sources we checked.

Backup is where the story has improved this year. Microsoft announced that iOS Authenticator would get a better backup and restore experience beginning in August 2026, using iCloud and iCloud Keychain with end-to-end encryption. That is a real step, because the old complaint about the app was that moving to a new phone could feel like a gamble. Another planned change to personal-account backup is reportedly scheduled for January 2027, so check Microsoft’s notes before you rely on a specific restore path.

What changed for Microsoft users this year

Three changes stand out. Password storage and autofill disappeared from the app in mid-2025, according to two independent reviews, which turned it back into a pure authentication tool. Microsoft reportedly announced that Authenticator would block Entra credentials from being added or used on rooted or jailbroken iOS and Android devices. And Microsoft’s Entra announcements reportedly schedule the retirement of Microsoft-provided SMS and voice authentication for October 30, 2026. After that date, organizations that still want those methods must pick a telephony provider from the Microsoft Security Store.

That last item is the quiet driver behind many “switch to Authenticator” memos landing this month. When the phone-call fallback goes away, the app on your phone becomes the main way in. Reportedly, Microsoft also began automatically enabling passkeys on September 1 for users who relied on its SMS or voice methods. If you manage a tenant, the choice between Microsoft’s identity stack and a rival matters more than the choice of app, and our breakdown of Okta versus Microsoft Entra ID covers how the two platforms handle this.

One trap for the unwary: version numbers. The build 6.2606.4246 appears in Microsoft’s release notes for Teams device apps, dated July 2026, and it is not the number you will see on your phone. Do not use it to judge whether your phone app is current. Check the store listing instead.

Why only third? Because the app’s strengths belong mostly to people inside Microsoft’s ecosystem, and its backup path leans on Apple’s cloud on iPhone. For a freelancer with accounts at thirty unrelated websites, a neutral app such as 2FAS leaves fewer strings attached. For a nurse, teacher or analyst whose login is a Microsoft account, Authenticator may beat everything else on this list.

Google Authenticator and Ente Auth: Sync-First Choices

Both apps pitch the same idea: your codes follow you across devices, so a lost phone is an inconvenience instead of a crisis. They differ in who holds the keys. Google ties sync to your Google Account. Ente builds around end-to-end encrypted backups. Neither has a rich body of confirmed 2026 release data, which is why they sit in the middle of the ranking.

Google Authenticator: simple, and tied to one account

Google Authenticator remains an active Google product, and Google’s support guidance reportedly still walks users through the time-correction tool. That tool exists for a reason. The guidance says a phone clock that drifts by about 30 seconds can make codes fail, so if your codes get rejected, fix the clock before you blame the website.

The headline feature is optional cloud sync. When you choose it, entries sync with a Google Account. The risk is on the other side of that choice. Google community guidance published this week says entries that were not backed up or transferred before a device was lost generally cannot be recovered, and you would have to restore access through each service’s own recovery process. That is a slow, annoying afternoon when you have forty accounts.

We found no confirmed Authenticator-specific release, price change or policy change between late July and October 23, 2026. Google’s recent announcements, such as passkey improvements on October 8 and selfie-video account recovery on October 15, concern the Google Account itself rather than this app. Those are worth knowing about because passkeys are chipping away at the one-time-code model, a shift we unpack in our guide to passkeys versus passwords and 2FA. For now, Google Authenticator is a fine pick if you want minimal fuss and you turn sync on today.

Ente Auth: encrypted sync from a privacy-focused company

Ente describes its app as an open-source 2FA authenticator with end-to-end encrypted backups, which is the exact pairing security-minded users look for. A third-party review describes it as free and usable without an account, with encrypted backups and sync once you create one. Because that review is the only source for the account and price details, treat them as likely rather than certain and read Ente’s own page before you commit.

Development looks lively. Ente Auth has reportedly shipped fixes for imports from 2FAS, support for multi-QR exports from Google Authenticator, and preservation of notes when importing from Aegis and Bitwarden. Those import fixes matter because they make Ente a decent landing spot when you leave another app. We would rank it higher if more of its details had a second confirming source.

Authy: Why It Ranks Last for New Setups

Authy used to be the default recommendation for people who wanted multi-device sync, and a lot of readers still have it installed. The sixth-place finish reflects what Twilio has stepped away from rather than a current failure. Twilio, which owns the product, has been narrowing Authy for years, and the pattern tells you where the roadmap is not going.

The timeline is documented. Twilio stopped supporting Authy customers who used only SMS or voice authentication in November 2022. Customers already using Authy TOTP or push before Twilio’s later cutoff remain supported. The Authy Chrome app and extension reached end of life in 2020, and the desktop apps followed on March 19, 2024. Twilio’s documentation also directs new development to Verify v2 and says the Authy API is closed to new customers with eventual deprecation planned, though it gives no end date.

What does that mean for a normal user? The consumer app still works, and Twilio’s pages describe it as a free tool for generating one-time codes. We found no Authy-specific change in the past three months, and no store listing with a fresh version number came back in our checks. That silence is the problem. When a security app goes quiet, you cannot tell whether it is stable or neglected, and you only learn which one after something breaks.

Our advice splits in two. If Authy is already set up and working, there is no emergency, but plan a move before a forced one arrives, using the migration guide below. If you are choosing today, pick one of the other five. The one real edge Authy once held, desktop access, is gone, which removes the strongest reason to start with it.

Benchmarks and Industry Data: What the Numbers Say

Because no one benchmarks code generators against each other, the useful numbers come from adoption and awareness research. The table gathers five data points from four independent sources. Each tells you something about why backup and ease of use matter more than raw features.

Data pointFigureSource and dateWhat it means for you

Chrome Web Store users of the top free authenticator extension9,000,000Authenticator.sh, as of Sept. 28, 2026Browser-based code tools have a large audience

A caution on the last row. The page that reports it comes from a company that makes one of the products it compares, and it says so openly. The extension in question, by authenticator.cc, had its store build last updated in August 2024. A big user count is not the same as an actively maintained app, so use the figure for scale and not as an endorsement.

Expert and research citations

Pew Research Center reported in 2023 that “In 2023, 48% of U.S. adults correctly identified an example of two-factor authentication.” The same analysis found a wide age gap. In Pew’s words, “In 2023, 68% of U.S. adults ages 18 to 29 correctly identified an example of two-factor authentication, compared with 26% of adults ages 65 and older.” Pew’s 2019 report put the earlier figure at a much lower level: “In 2019, 28% of U.S. adults correctly identified an example of two-factor authentication.”

On the enterprise side, Gartner’s 2025 Market Guide for User Authentication, hosted by Thales, includes this projection: “Gartner projected that by 2027, 90% of enterprises will fully meet their MFA needs for remote and cloud access using the native capabilities of access-management tools, lowering total cost of ownership by 40%.” That is a forecast, not a measurement, and it applies to companies rather than individuals. Still, it explains why the big-vendor apps keep adding features, and why the independent apps compete on privacy and control instead.

Real-World Examples: Six Cases That Show the Differences

Specs only go so far. These six cases show how the design choices play out. Four come from documented events and two are labeled scenarios built to show how a typical user would be affected.

Case 1: A university switches from Duo to Microsoft Authenticator

The Daily Illini reported on October 21, 2026 that the University of Illinois is switching from Duo to Microsoft Authenticator for multifactor sign-in. It is a clean example of the Gartner trend in practice: an institution already running Microsoft services picks the bundled app instead of a separate vendor. For students, the lesson is to expect an account-bound setup, so enroll the new phone before you wipe the old one.

Case 2: Authy desktop users lose their app

When Twilio ended the Authy desktop apps on March 19, 2024, anyone who relied on a computer-based code screen had to change habits. It cost them nothing in money, but it taught a lasting lesson about depending on a feature a vendor can switch off. Apps with open code, like Aegis and 2FAS, cannot be pulled from your phone by a corporate decision, though they can still stop receiving updates.

Case 3: An Aegis icon pack that could touch the vault

Aegis v3.4.3 fixed a flaw in which a malicious icon pack could overwrite internal files, potentially including the vault file. The bug is a reminder that import features are an attack surface. The fix landed September 6, 2026, and the project’s changelog is public. Rule of thumb: only import icon packs, backups and exports from sources you trust.

Case 4: Microsoft users who stored passwords in the app

People who kept passwords in Microsoft Authenticator had to relocate them after the mid-2025 removal of password storage and autofill. Anyone who skipped that move and still trusts an old guide is working from outdated advice. The case argues for keeping codes and passwords in separate tools, or in one tool you chose on purpose.

Case 5 (scenario): A gamer protecting three accounts

Picture a player with a Steam account, an Epic account and a Discord login. Each service supports one-time codes, and each is a favorite target for takeover. Our Steam Guard and Discord 2FA guide walks through the setup, and this player should scan every QR code into one app that has encrypted backup, such as 2FAS, so a broken phone does not cost them a game library. The same logic applies to the Fortnite two-factor setup, where the extra step also unlocks free rewards.

Case 6 (scenario): The unbacked-up phone in a lake

Imagine a user with forty accounts in Google Authenticator who never turned on sync. The phone goes into a lake. Per Google’s community guidance, those entries generally cannot be recovered, so the user works through forty separate account recovery flows, some of which take days. Five minutes of setup would have prevented all of it. This scenario is the reason our ranking puts backup first.

Which Authenticator App Fits Which User: Seven Picks

The overall ranking answers “which app is safest if I lose my phone?” Your own situation may change the answer. These seven recommendations match the app to the person, with the reasoning in plain terms.

  • iPhone owner who wants no account: 2FAS Authenticator. The iOS app hit version 6.0.1 on October 22, 2026, runs without sign-up, and sends encrypted backups to your own cloud storage.
  • Android power user: Aegis Authenticator. An encrypted vault, no accounts, a GPL license and a release on September 6, 2026 add up to the most control per tap.
  • Employee or student on Microsoft sign-in: Microsoft Authenticator. Your admin probably requires it, and it adds passwordless sign-in and passkeys on top of codes.
  • Google-only household: Google Authenticator with sync switched on today. Skip the lecture about vendor lock-in if every account you care about already lives in one Google login.
  • Multi-device user who wants encrypted sync: Ente Auth, after you confirm its account and sync terms on Ente’s own page.
  • Existing Authy user: stay put for now, then plan a move to 2FAS or Ente Auth before Twilio narrows the product further.
  • Older relative or non-technical family member: whichever app you will help them maintain. Pew’s 2023 data shows only 26 percent of adults 65 and older identified an example of two-factor authentication, so pick the simplest option and write the backup steps on paper.

The password-manager route

Some people prefer to keep one-time codes inside their password manager. Bitwarden is the usual example, with a Premium plan reported at $19.80 per year. It is active, and a secondary report says that from October 9, 2026 its app-store releases would be commercially licensed builds while the GPLv3 source code continues to be published. Treat that licensing note as unconfirmed until Bitwarden says it directly. The convenience is real, since codes autofill next to passwords. The risk is concentration: one vault breach exposes both factors. Security teams argue about this trade, and there is no universal winner.

Small-business owners should add one more layer to the picture. An authenticator code does not stop a phishing page that relays your code in real time, which is why attackers keep targeting inboxes. If you run a company, pair whichever app you choose with email filtering, and our comparison of Proofpoint, Mimecast and Defender for Office 365 shows how those gateways differ on price and coverage.

Migration Guide: Moving Your Codes to a New App

Switching apps is where people get hurt, so slow down. The goal is simple: never be in a state where a code exists in only one place you cannot recover. Follow these steps in order, and do not delete the old app until the last step.

  1. List your accounts. Open the old app and write down every service it holds. Mark which ones guard money, email and work, since those come first.
  2. Choose the destination. Use the ranking above. If you are leaving Authy, 2FAS and Ente Auth are the natural landing spots.
  3. Turn on backup in the new app before you import anything. Set a strong passphrase for the encrypted backup and store it in a place other than the phone.
  4. Check what the old app can export. Google Authenticator offers a multi-QR transfer, and Ente Auth reportedly added support for importing those multi-QR exports on October 19, 2026. Aegis imports encrypted Proton Authenticator exports, and 2FAS added importers in its iOS 6.0.1 release.
  5. If no export exists, re-enroll each account. Open each service’s security settings, disable the old code, and scan a fresh QR code with the new app.
  6. Test every account with a real sign-in. Use a private browser window, and enter the code from the new app. A code that appears on screen has not proved anything until a login accepts it.
  7. Save each service’s recovery codes. Print them or store them in your password manager. They are the lifeline when everything else fails.
  8. Fix your phone clock. Time-based codes depend on accurate time. If one account rejects a correct-looking code, check automatic time first.
  9. Run both apps for a week. Keep the old one installed while you log in normally. Any account you forgot will announce itself.
  10. Remove the old entries, then the old app. Only now delete the codes. Back up the new vault one more time afterward.

The secret behind each code is a Base32 string packed into a standard URI, and that is what a QR code carries. Seeing the format helps you understand why a scan is all it takes to clone an entry onto a second device, and why a screenshot of that QR code deserves the same care as a password:

otpauth://totp/ExampleSite:[email protected]?secret=BASE32SECRETHERE&issuer=ExampleSite&digits=6&period=30

Delete any screenshot of a setup QR code once the app has scanned it. For more on defending accounts beyond codes, browse our wider cybersecurity coverage.

Pros and Cons of Each Authenticator App

AppProsCons
2FAS AuthenticatorFree, no ads, no account, encrypted backups to your own cloud, Android and iOS, active releasesBackup is manual to enable, and some Android build details rest on single sources
Aegis AuthenticatorFree, GPL, no account, encrypted vault, fresh release on Sept. 6, 2026, public security fixesAndroid only, and you manage your own backup file
Microsoft AuthenticatorBest fit for Microsoft work and school logins, passkeys and passwordless sign-in, encrypted iCloud backup on iOSPassword storage and autofill removed, ties you to Microsoft, restore paths still changing
Ente AuthOpen source, encrypted backups, active development with import fixesFewer independently confirmed details, so verify account and sync terms
Google AuthenticatorFamiliar, simple, optional Google Account syncUnsynced entries generally cannot be recovered, and no confirmed 2026 changes
AuthyLong track record, existing users remain supportedDesktop apps ended March 19, 2024, API closed to new customers, little visible activity

Read the table as a map of trade-offs and not a scoreboard. The open-source apps give up some polish and hand you more responsibility. The big-vendor apps give you convenience and take some independence. Neither side is wrong, though each fits a different person.

Verdict: 2FAS Wins on Backup Safety, Aegis and Microsoft Close Behind

For most readers in October 2026, the best authenticator app is 2FAS Authenticator. It is free, carries no ads, needs no account, offers encrypted backups to your own cloud, runs on both major phone platforms, and recently shipped a redesigned iOS release. No other app on this list clears all of those bars with verified sources behind each one.

Aegis takes second place and wins outright for Android users who want a vault they fully control, with v3.4.3 on September 6, 2026 adding Proton imports and closing an icon-pack flaw. Microsoft Authenticator takes third and should be your first choice if your sign-in belongs to Microsoft, because it carries passkeys, passwordless login and a better iOS backup path since August. Ente Auth looks promising but needs more confirmed detail. Google Authenticator works if you turn sync on. Authy is the app to leave, on your own schedule.

The data supports a simple message. Pew’s numbers show that about half of U.S. adults could name an example of two-factor authentication in 2023, and Gartner expects most enterprises to lean on native access-management tools by 2027. The apps you choose matter less than whether you back them up and test the restore. Pick one from this list, set up the backup tonight, and log in once from the new phone before you need to. That habit beats any feature on any spec sheet.

Frequently Asked Questions

What is the best authenticator app in 2026?

For most people it is 2FAS Authenticator, because it combines a free price, no account requirement, encrypted backups and support for both Android and iOS. Android users who want maximum control should pick Aegis. People who sign in to Microsoft work or school accounts should use Microsoft Authenticator.

Is Google Authenticator still a good choice?

Yes, with one condition. It remains an active Google product, and Google’s support guidance still covers it. Turn on Google Account sync, because community guidance says entries that were never backed up or transferred generally cannot be recovered after a device is lost.

Is Authy shutting down?

We found no shutdown notice. Twilio’s documentation still treats the consumer app as active, but it ended the desktop apps on March 19, 2024 and closed the Authy API to new customers, pointing developers to Verify v2 instead. Existing users should plan a move without panicking.

Can I use an authenticator app without creating an account?

Yes. 2FAS and Aegis both work with no account. A third-party review says Ente Auth can also be used without one, though sync needs an account. Microsoft Authenticator and Google Authenticator tie some features, such as backup, to their vendor accounts.

What happens if I lose my phone?

If you had an encrypted backup, install the same app on a new phone and restore it. If you did not, you must use each service’s recovery process, which is slow. Saving the recovery codes each service gives you during setup makes that process far easier.

Are authenticator apps safer than text-message codes?

Generally yes, because a code generated on your device cannot be intercepted in a text message. Microsoft’s Entra announcements reportedly schedule the retirement of its own SMS and voice authentication for October 30, 2026, which signals where large vendors are heading. Passkeys go further, since they resist phishing in a way one-time codes do not.

Should I put my codes in a password manager instead?

It depends on how you weigh convenience against concentration of risk. A password manager such as Bitwarden, reportedly $19.80 per year for Premium, autofills codes beside passwords, but a single compromised vault would expose both. A separate authenticator keeps the two factors apart.
