This is the official server-side API for the Open Source 2FAS project.

2FAS (Two-Factor Authentication Service) is a user authentication method that provides an additional layer of security for online accounts. In addition to a username and password, 2FAS uses a second factor, such as a one-time password (OTP) shown on a user's phone, to verify a user's identity. This helps prevent unauthorized access to accounts, even if a password is compromised.

• Connecting the 2FAS app with the 2FAS browser extension (API and websocket API)
• Connecting to the 2FAS icons system
• Connecting to 2FAS support (receiving debug log files)
• Sending in-app notifications to 2FAS app users
• Other miscellaneous features

We use GitHub for bug reports. Please visit the 2FAS Server API issues page to search for and report any bugs you may have found. Before adding a new issue, please search for existing issues to avoid duplicates.

For reporting security issues only, please send a detailed description of the vulnerability to [email protected]. Do not use this address for general inquiries or bug reports unrelated to security concerns.
