## Description

Most 2FA authenticator extensions require trusting an unknown publisher with your authentication secrets. This extension is fully transparent, open-source, and runs entirely on your machine — no accounts, no servers, no telemetry.

You can export data from your Google Authenticator app and have access to the same code without need to pick up your phone every time.
