What Mauth is

Mauth is a free Android two-factor authentication app for time-based and counter-based one-time passwords, using TOTP and HOTP. It is compatible with Google Authenticator and lists imports from Google Authenticator, Authy, Aegis, Microsoft Authenticator, and other apps exporting Google Authenticator-format data. Accounts can be added by scanning a QR code, selecting an image, entering details manually, or using deeplinks. Within the app, users can search, sort, group, edit, and delete accounts. Access protection includes biometric authentication and a PIN, while the account database is encrypted. Exports include individual or batch QR codes, otpauth:// URIs, and encrypted data. Backup options listed by the project include Nextcloud, ownCloud, Google Drive, Dropbox, and OneDrive. The privacy policy says registration is unnecessary, no information is obtained during use, data is not shared with third parties, and precise device location is not collected. Mauth is GNU GPL version 3 or later software, downloadable from F-Droid and GitHub Releases. F-Droid version 0.11.0 requires Android 6.0 or newer.
