Our verdict on GNOME Authenticator

GNOME Authenticator is an open-source Linux desktop application for generating two-factor authentication codes. It supports time-based, counter-based, and Steam methods, making it suitable for Linux users managing accounts that rely on TOTP, HOTP, or Steam codes. The app also supports SHA-1, SHA-256, and SHA-512 algorithms, giving users flexibility when adding services with different authentication requirements.

Account setup centers on QR-code scanning: users can scan with a camera or use a screenshot. GNOME Shell search integration helps users find accounts from the desktop environment, while password locking adds a local access control layer. Backup and restore support includes formats from several established authenticator applications, including encrypted Aegis data. These features make the app practical for users moving accounts into a Linux-based workflow or maintaining a local authenticator collection.

GNOME Authenticator is free and open source, with Linux as its supported platform. It does not provide multi-device synchronization, mobile clients, push approvals, or team administration. That makes it a focused choice for individual Linux desktop users who prefer open-source software and local code generation. Users who need their authenticator accounts available across phones and desktops, or who require centralized administration for a team, should choose an alternative with synchronization and organization-wide controls.
