Kerveros

Kerveros is a desktop application developed for Linux systems to generate time-based and counter-based two-factor authentication codes. It serves as an offline authenticator utility, allowing users to manage multiple account tokens and retrieve verification numbers directly from their local machine without relying on browser extensions or mobile devices.

The interface presents stored authentication entries and computes numerical passcodes based on shared secrets and standard cryptographic algorithms. The software requires manual entry or import of seed credentials and provides no network synchronization features, maintaining all data storage locally on the host system under the GNU General Public License version 3 or later.
