Scores (0–10) come from our published methodology and are calculated without the developer's name. Facts are read from store listings, privacy labels and Exodus Privacy reports on the verification date.

4 of the 9 declare no data linked to you, while the two best-known names, Google Authenticator and Microsoft Authenticator, list six or more data categories linked to you on the App Store. Twilio Authy is the only app here whose listing requires an account, tied to your phone number.

How we picked

We ranked nine authenticator apps with the same blind scorer on public data only. Names, developers and the operator flag are removed before scoring, so the order comes from the facts. None of the apps is made by Lapnito, the company behind this site.

We fixed the required features from the user's job before looking at any candidate: time-based one-time codes (TOTP), an encrypted backup or export so you can move to a new phone, codes that work offline, and an app lock with a PIN or biometrics. A feature counts only if the store listing or the developer's own page names it. Price, ads, privacy labels, Data safety and update dates come from the App Store and Google Play, trackers from Exodus Privacy reports where they exist. All facts were checked on 11 November 2026. We did not install or test any app, and privacy labels are the developers' own declarations. The weights are explained on the methodology page.

The ranking

Proton Authenticator scored highest because its listings name all four required features and it is free, ad-free and declares only diagnostics, not linked to you. Aegis and 2FAS follow; each lacks one named feature.

1. Proton Authenticator & 2FA (iPhone, Android)

Proton Authenticator & 2FA by Proton AG, the Swiss company behind Proton Mail, stores your 2FA codes on the device, works offline on mobile and desktop, and offers backups and an export you can protect with a password. The Google Play listing names an app lock with biometrics or a PIN, and a Proton account is optional. The App Store label lists only diagnostics, not linked to you. It is free, open source and shows no ads, with a 4.6 rating from about 590 App Store ratings.

It is a younger app with fewer ratings than the big names, and the last Google Play update was on 24 July 2026.

2. Aegis Authenticator (Android)

Aegis Authenticator - 2FA App by Beem Development is a free, open-source (GPLv3) app with an encrypted vault you unlock with a password or biometrics, encrypted export and automatic vault backups, and import from other authenticators. Google Play reports no data collected or shared, and Exodus Privacy finds 0 trackers and only the camera and biometric permissions. It has a 4.7 rating from about 6,400 reviews.

It is Android only, and its listing does not state that it works offline, so that feature did not count.

3. 2FA Authenticator (2FAS) (iPhone, Android)

2FA Authenticator (2FAS) supports TOTP and HOTP, works offline, locks with a passcode or biometrics and needs no account. It is open source, has a browser extension for one-tap sign-in, and its App Store label lists only diagnostics, not linked to you. It has a 4.7 rating from about 36,000 App Store ratings and was updated on 22 October 2026.

Its listing mentions token backups but does not say they are encrypted, so that feature did not count. It needs iOS 18.6 or later.

4. Ente Auth (iPhone, Android)

Ente Auth - 2FA Authenticator by Ente Technologies offers end-to-end encrypted cloud backups, sync across phone, desktop and web, and offline use with optional sign-up. If you create an account, its label lists contact info, user content and identifiers linked to you. Its listings do not name an app lock.

5. Twilio Authy (iPhone, Android)

Twilio Authy offers encrypted cloud backups, multi-device sync and offline token generation, with a 4.7 rating from about 54,000 ratings. It requires an account tied to your phone number, its label lists location, contact info and identifiers linked to you, and Twilio ended the desktop apps in March 2024.

6. FreeOTP Authenticator (iPhone, Android)

FreeOTP Authenticator by Red Hat is open source (Apache 2.0), generates TOTP and HOTP codes on the device and works offline. Both stores declare no data collected. Its listings name no encrypted backup and no app lock, it has a 3.2 rating from 172 ratings, and its last update was on 17 February 2026.

7. Google Authenticator (iPhone, Android)

Google Authenticator has a 4.9 rating from about 1.2 million ratings, works without a connection and can sync codes to your Google Account or move them by QR code. Its App Store label lists eight data categories linked to you, including location, contacts and identifiers, and its listings name no app lock or encrypted export. Exodus Privacy finds 0 trackers.

8. Bitwarden Authenticator (iPhone, Android)

Bitwarden Authenticator generates TOTP codes, unlocks with biometrics and works with or without a Bitwarden account. The Bitwarden help page describes a manual export but no encrypted backup, the label lists your email address linked to you, and it has a 3.5 rating from 95 App Store ratings.

9. Microsoft Authenticator (iPhone, Android)

Microsoft Authenticator is the natural choice for work and school accounts, with push approvals, passwordless sign-in and a Face ID app lock. It ranks last on this privacy-focused checklist because its label lists six data categories linked to you, Google Play says location is shared with third parties, and its listings do not state offline use or an encrypted export.

Which authenticator app should you pick?

On iPhone, pick Proton Authenticator or 2FAS; on Android, Aegis is the most private choice and Proton the most complete. If you want encrypted cloud sync across phone and computer, Ente Auth is the open-source option. Keep Microsoft Authenticator if your employer requires push approvals, but use a separate app for personal accounts if privacy matters to you. For passwords themselves, see our privacy-friendly password managers, and for chats, the most private messaging apps.

When not to use an app

For your most important accounts, such as email and banking, a hardware security key with passkeys or FIDO2 resists phishing better than any code app, because a fake site cannot reuse it. Also, never rely on an authenticator without a recovery plan: store the backup codes each service gives you on paper or in a password manager, and export your tokens before you change or reset your phone.

FAQ

Which authenticator app is the most private?

On our list, Proton Authenticator, Aegis, 2FAS and FreeOTP declare no data linked to you, and Exodus Privacy finds 0 trackers in Aegis. Labels are self-declared, so treat them as a strong hint rather than proof.

Do authenticator apps work without internet?

Yes. TOTP codes are calculated from a shared secret and the phone's clock, so no connection is needed. Only cloud sync and backups need the internet.

Is Google Authenticator safe to use?

It generates standard codes and Exodus finds 0 trackers, but its App Store label lists eight data categories linked to you, and cloud sync ties your codes to your Google Account.

What happens if I lose my phone?

Without a backup you must use each service's recovery codes or support process. Apps with an encrypted backup or export, such as Proton Authenticator, Aegis and Ente Auth, let you restore your codes on a new phone.

Is SMS two-factor authentication good enough?

It is better than nothing, but SMS codes can be intercepted or redirected through SIM swapping. An authenticator app or a security key is the safer choice.
