What GNOME Authenticator is

GNOME Authenticator is a free Linux desktop application for generating two-factor authentication codes. It supports time-based, counter-based, and Steam methods, using SHA-1, SHA-256, or SHA-512 algorithms. Accounts can be added by scanning QR codes with a camera or reading them from screenshots. A password can lock the application. Backup and restore support includes FreeOTP+, Aegis in encrypted or plain-text formats, andOTP, and Google Authenticator. The app provides a GNOME Shell search provider and is distributed through Flathub, where x86_64 and aarch64 architectures are listed. The latest listed release is version 4.6.2, released March 25, 2025. Flathub lists the Free plan at no cost. There is no trial. The app page names Bilal Elmoussaoui as maintainer, links to an issue tracker, and provides a way to contribute translations. Push approvals, multi-device sync, and team administration are not supported.

Verdict

GNOME Authenticator provides core one-time-password generation and migration tools at no cost. Its Linux-only desktop scope and lack of synchronization or team controls make it a personal authenticator rather than a managed service.
