Ente Auth — The Complete Guide: Open-Source Two-Factor Codes with Encrypted Backup
Ente Auth is an app for one-time codes (TOTP) for secure sign-in to email, cloud, software and supplier accounts. The code is open source under AGPL-3.0, and the app is completely free, with no paid tiers. There are versions for Windows, macOS and Linux, for the browser, and for Android and iOS.

- TOTP codes — for any service that supports app-based two-factor sign-in.
- Encrypted sync — the same codes on phone and computer, with end-to-end encryption.
- Backup — replacing your phone does not wipe your access to accounts.
- Import and export — move in from other apps and leave whenever you like.
- Offline mode — use on a single device with no account at all.
What you should know
Sync and backup need an Ente account; without one the codes are stored only on the device. If you forget both the account password and the recovery key, the codes cannot be restored. Security tip: keep the recovery key printed in a safe place, and also keep the one-time backup codes each service gives you when you turn on 2FA.
