Proton Authenticator
Proton
Proton Authenticator is a privacy-first two-factor authentication app that generates time-based one-time passwords to add an extra layer of login security for online accounts beyond just a password, so users can secure accounts across all their devices. It is open source and uses end-to-end encryption, meaning all cryptographic operations and secret keys are generated and stored locally, and even Proton cannot see your unencrypted 2FA data, offering transparency and strong privacy by design. Users can sync 2FA codes across devices with encrypted backups (including via iCloud or a Proton Account), import existing codes from other authenticator apps, and export them if needed, giving flexibility and control over 2FA secrets without vendor lock-in. Proton Authenticator is free to use, has no ads or tracking, and supports secure practices like biometric locks and offline access, so users can generate login codes.Starting Price: Free -

Ente Auth
Ente
Ente Auth is a free, open-source two-factor authentication app that helps users generate and manage time-based one-time passwords to secure logins for online accounts with an extra layer of verification beyond just a password, offering end-to-end encrypted backups so you never lose your codes and they remain private even to the service itself. It syncs codes across mobile, desktop, and web clients using fully encrypted channels, lets users import existing 2FA tokens by scanning QR codes or manual entry, and provides features like offline code generation, tagging and searching of codes, pinning favorites, icon identification, and quick “next code” display for faster logins. Backups are encrypted with audited cryptography, giving users peace of mind that only they can decrypt and access their 2FA secrets, and codes can be shared securely with teammates via encrypted links with optional expirations.Starting Price: Free -
