Ente Auth

Ente Auth is a free authenticator for storing two-factor codes, including TOTP and HOTP. For account users, it provides end-to-end encrypted cloud backups and sync across mobile, desktop and web devices; the maker says its cryptography has been externally audited. The app is open source and supports importing from services including 2FAS Authenticator, Aegis, Bitwarden, Google Authenticator, LastPass, Proton and Raivo OTP. Codes can be organized with search, tags, pins, notes and custom sorting, and shared through links that expire after 2, 5 or 10 minutes. Export options include plain text, encrypted files and HTML QR codes compatible with Google Authenticator. Auth can also be used without an account, but those codes remain on the device and are not synced or backed up to Ente. App lock options include a device lock, 4-digit PIN or password; this protects the interface, not the stored data through re-encryption. It is available on Android, iOS, Linux, macOS, Windows and web.

Who it is for

It suits people who want a free, cross-platform authenticator with encrypted backups and data import and export. People using it without an account should know their codes will stay local and will not be backed up to Ente.

What is good

Free on Android, iOS, desktop and web.
End-to-end encrypted cloud backups for account users.
Open source with data import and export.
Codes can be organized with tags, pins and notes.
Sharing links expire after 2, 5 or 10 minutes.

What to know first

Offline codes are not synced or backed up.
App lock does not re-encrypt Auth data.
Account backups involve an email address.

Verdict

Ente Auth combines cross-platform code access with encrypted backups for account users and several import and export options. Its no-account mode is local-only, and the app lock protects the interface rather than re-encrypting stored data.
