Ente Auth vs SAP Authenticator

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

SAP Authenticator is a free mobile app that generates time-based passcodes for systems requiring one-time password authentication. Each code works for one login attempt, and the app creates a new one every 30 seconds. A passcode can act as a second factor or as an alternative password. The app supports multiple accounts, which can be configured by scanning a QR code or entering a secret key. Online account setup is also available only with SAP Authenticator. For accounts set up online, administrators add applications; users cannot maintain those applications themselves. Users can save applications in the app and access them later through mobile single sign-on without another authentication step. SAP documentation describes OTP authentication and mobile SSO use with SAP Single Sign-On and SAP Fiori Client. The app runs on iOS and Android and can be protected with a password. SAP recommends protecting the app with a logon password and using two-factor authentication when the scenario allows it.
