In their own words
Proton Authenticator
Proton Authenticator generates time-based one-time codes for two-factor authentication, adding a code at login to help secure accounts. It can display codes without an internet connection, and a Proton Account is not required to use it. Signing in is optional and enables code syncing across devices. Users can import codes from Google Authenticator, 2FAS, Aegis Authenticator, Bitwarden Authenticator, Ente Auth, and LastPass Authenticator, then export their codes from the app. Backups can be stored locally or in the cloud, with end-to-end encrypted sync between devices. Proton says its servers cannot access synced data in unencrypted form; when sync is on, entries are protected with 256-bit AES-GCM. The app is open source, and its vault can be unlocked with face or fingerprint recognition. It is available for Android, iOS, Linux, macOS, and Windows; Android is also available through F-Droid. Proton Authenticator is free on all listed platforms, with no ads or tracking.
