TOTP generator for Gnome

Project description

oathguardian: one-time password (TOTP/HOTP) generator

Oathguardian is a GTK-3 graphical tool for generating Time-based one-time password as defined in RFC6238. Those one-time passwords are frequently used as a two-factory authentication mechanism, by using a smartphone application such as Google authenticator.

Oathguardian permits to store the key secret either in a secret service such as Gnome Keyring ; or into a Yubikey 4. The yubikey is an USB device that has many security-related usages, such as storing a PGP private key, or doing TOTP/HOTP computations.
