OTP Authenticator: 2FA App

Novum Software

About this app

OTP Authenticator is an offline 2FA authenticator app that generates time-based one-time passwords (TOTP) for two-factor authentication, adding an extra layer of security to every online account you sign in to.

Use this authenticator app to add an account by scanning its QR code or entering the setup key by hand, and it produces the rotating 6- or 8-digit verification codes you need to log in. These are the same two-factor (2FA) and multi-factor authentication (MFA) codes used by Google, GitHub, Microsoft, Facebook, Amazon, and thousands of other services that support authenticator apps.

WHY CHOOSE THIS AUTHENTICATOR
• 100% offline two-factor authentication. Codes are generated on your device, with no account, sign-up, login, or internet connection required.

• A private, no-tracking alternative to other authenticator and 2FA apps.
