Javascript: Two-Factor Authentication
Implement two-factor authentication in PHP using TOTP. Enhance security by integrating Google Authenticator and handling errors effectively for robust user authentication.
This PHP snippet implements two-factor authentication (2FA) using Time-based One-Time Passwords (TOTP). It enhances security by requiring users to provide a second form of authentication in addition to their password.
The code integrates with the Google Authenticator app, generating a QR code for users to scan and setting up TOTP for secure authentication.
Error handling ensures that the TOTP generation and verification processes are robust, providing clear feedback if the authentication fails or if there are issues with the QR code generation.
The snippet is ideal for applications that require high security, such as financial services, online marketplaces, and any system handling sensitive user information.
Implementing 2FA is a critical step in enhancing the security of user accounts and protecting against unauthorized access.
