Audience
Anyone who wants a private, open source, cross-device two-factor authentication app that secures logins with time-based one-time codes
About Proton Authenticator
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.
