LibreOTP: Open Source One-Time Password Authenticator Apps

LibreOTP is an open source one-time password authenticator app for Android, enabling two-factor authentication for logins by generating timed one-time passwords based on open standards.

What is LibreOTP?

LibreOTP is a free and open source one-time password authenticator application for Android. It allows users to enable two-factor authentication for logins and other services by generating timed one-time passwords that are valid for a short period.

LibreOTP is based on Google Authenticator and implements common OTP standards like HMAC-Based One-Time Password (HOTP) and Time-based One-Time Password (TOTP). It can scan QR codes to easily set up accounts. The app generates 6-digit one-time passwords that refresh every 30 seconds.

As an open source app, LibreOTP places priority on user privacy and security. It does not require any unnecessary permissions or collect private user data. The app is available on F-Droid as well as the Google Play Store.

Overall, LibreOTP is a lightweight, secure and privacy-focused open source authenticator app for two-factor authentication. Its adherence to OTP standards and open source nature makes it a good alternative to commercial solutions like Google Authenticator or Authy.
