Ente Auth Best for: People who want encrypted sync, open source and a web view of their codes. Ente Auth suits people who want free encrypted sync across phone, desktop and web, with open code and a recent public audit. It imports from nine named apps and exports encrypted files. The catch: Ente documents no public bug bounty, and its pages do not mention passkeys or push approval. ## 2. Proton Authenticator Best for: People who want encrypted sync and a Windows or Linux app. Proton Authenticator suits people who want codes on a phone and a desktop, with encrypted backup and no paid plan. It imports from several rival apps and exports your codes. The catch: Proton names no outside audit of this app yet, and Proton's pages do not mention passkeys, push approval or counter-based codes. ## 3. Zoho OneAuth Best for: People who want free encrypted backup and the same codes on a phone and a computer. OneAuth suits people who want free encrypted backup and syncing across a phone and a computer. It also offers folders, push sign-in approval and an app lock. The catch: backup needs a Zoho account, and its pages publish no outside audit, source code or counter-based code support. ## 4. 2FAS Auth Best for: iPhone and Android users who want a free app without an account. 2FAS Auth suits people with a phone who want a free, open-source app with no sign-up and backup in their own cloud. PIN or biometric lock, groups and search are included. The catch: it is phone-only, the backup password is optional, and its pages name no outside audit or bug bounty. ## 5. Stratum Best for: Android users who want an offline, open-source app they fully control. Stratum suits Android users who want an offline, open-source app with strong backup encryption and no sign-up. It supports TOTP, HOTP, categories and a password or biometric lock. The catch: it runs only on Android, has no cloud sync of its own, so cloud backup needs DAVx5, and publishes no audit or bug bounty. ## 6. Bitwarden Authenticator Best for: Phone users who want a free, audited, open-source code app with no sign-up. Bitwarden Authenticator suits phone users who want a free app from a vendor that publishes mobile audit reports. It needs no account and imports from several other apps. The catch: backup depends on the phone's own cloud backup, there is no desktop app, and its bug bounty is private. ## 7. Aegis Authenticator Best for: Android users who want an open-source app and control over where backups go. Aegis suits Android users who want free, open-source code and control over their backups. Backups can go to cloud storage you choose, and the vault is locked with a password you hold. The catch: it runs only on Android, and its pages publish no outside audit, bug bounty or multi-device sync. ## 8. Google Authenticator Best for: People who want codes on several phones and already use a Google Account. Google Authenticator suits people who want free codes that follow them to a new phone through a Google Account. It also offers transfer by QR code and a no-account mode. The catch: Google's page describes encryption in transit and at rest only, the official app is closed source, and it runs on phones only. ## 9. FreeOTP Best for: People who want a plain open-source app for HOTP and TOTP codes. FreeOTP suits people who want a simple open-source app on Android or iOS that supports HOTP and TOTP. Backup uses Google or Apple device backups, with encryption. The catch: its pages describe no export or import, no folders or search, and no audit or bug bounty, and F-Droid warns of backup problems. ## 10. Authy Best for: People who want encrypted cloud backup and multiple devices, and accept giving a phone number. Authy suits people who want encrypted cloud backup and the same codes on several devices, for free. It has an app lock and offline codes. The catch: an account needs your phone number, only phone apps are listed, and Twilio reported two security incidents involving Authy in 2022 and 2024. ## 11. LastPass Authenticator Best for: People who already use LastPass and want one app for push approval and codes. LastPass Authenticator suits people who already log in to LastPass and want push approval plus codes for other sites in one free app. It covers backup, a biometric lock, import and export. The catch: LastPass does not say who holds the backup key, a LastPass page limits Free-plan users to passwordless login with the app, and its pages name no audit firm, passkeys or HOTP. ## 12. Microsoft Authenticator Best for: People who mainly protect Microsoft accounts and want sign-in approval prompts. Microsoft Authenticator suits people whose main accounts are Microsoft ones, since it adds approval prompts and codes for other sites on iOS and Android. It has an app lock and a public bounty. The catch: Microsoft does not document a user-held backup key, and the app is mobile only.
