2FAuth is an open-source, self-hosted two-factor authentication (2FA) solution that provides an added layer of security for user accounts by requiring not only a password but also a verification code generated by the application. Designed to be privacy-focused and user-friendly, 2FAuth allows individuals and organizations to implement 2FA through TOTP (Time-based One-Time Password) protocols, making it compatible with a variety of popular authentication apps, such as Google Authenticator and Authy. This flexibility enables seamless integration into existing user authentication flows while enhancing overall security.
By self-hosting 2FAuth, users gain full control over their authentication process, ensuring that their sensitive data remains within a secure environment. The easy-to-follow setup and customizable features make it an attractive option for those looking to bolster their security without relying on third-party services. Additionally, 2FAuth provides detailed documentation and support, facilitating implementation and maintenance for developers and system administrators alike.
