To implement TOTP in Laravel, you can use a library such as “Google Authenticator” or “TOTP”.
Here are the general steps you can follow to implement TOTP in Laravel:
Tag: 2FA
Logic behind 2FA
Two-factor authentication (2FA) codes provide an extra layer of security for login systems by requiring the user to present two different forms of identification. The first factor is usually a password, and the second factor is generated by an application, such as Google Authenticator, or sent to the user’s phone as a text message. The 2FA code acts as a one-time password that is only valid for a short period of time and is required in addition to the password in order to log in. This helps ensure that even if someone has obtained the user’s password, they still cannot access the account without the 2FA code, adding an extra barrier to prevent unauthorized access.
