2FA Authenticator vs GNOME Authenticator

GNOME Authenticator

Free plan Linux

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.
