Authra is an offline two-factor authentication app. It generates the time-based one-time codes (TOTP) you use to sign in to Google, GitHub, Microsoft and thousands of other services - and it does it without an account, without the cloud and without any tracking.
Add accounts by scanning a QR code or entering a key by hand. Lock the app behind your fingerprint or PIN for an extra layer of protection.
