About Authenticator
Authenticator is a small GNOME application that generates the one-time codes many websites ask for as a second login factor. It supports both time-based (TOTP) and counter-based (HOTP) codes, so it can stand in for a phone authenticator app on a Linux desktop.
The project is hosted in the GNOME World group on GNOME's GitLab, where it has been developed since 2018 and publishes releases. It is free software under the GNU General Public License v3.0 or later.
