Open Two-Factor Authenticator aims to provide Two-Factor Authentication to browsers in a secure way. The Open Two-Factor Authenticator stores all your credentials in a local repository (directory). All credentials are encrypted with a passkey. This way you can sync the folder across multiple devices and still have your secure token safe.


  1. This is the first release of the extension, so the extension might be buggy. It is highly recommend to keep the original QR codes in a safe place to later have access to. Also dont forget to generate one-time keys when two factor is enabled in a web service.

  2. Still QR code scanning feature is not as accurate as it should be; meaning it might not be able to capture the code. If so use another QR code scanner, and paste the string in the "manual" tab.

  3. Please report bugs in the GitHub repo to help improving the application,
