How to implement TOTP to Laravel

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:

1. Install the library: Use composer to install the library, for example: composer require pragmarx/google2fa.
2. Configure the library: In your config/app.php file, add the library's service provider and alias.
3. Generate secret keys: Generate a unique secret key for each user and store it in your database. You can use the library's generateSecretKey method to generate the key.
4. Enable TOTP for users: Add a field to your user table to store the TOTP status and add a form to your user's settings page to enable TOTP.
5. Verify TOTP code: In your login process, prompt the user to enter their password and TOTP code. Use the library's verifyKey method to verify the code.
6. Add TOTP recovery: Provide a way for users to recover access to their account in case they lose access to their device. You can implement this by sending a recovery code to the user's email or allowing them to disable TOTP from their account settings.

Note: It's recommended to use the latest version of Laravel and the TOTP library for better security and compatibility. Additionally, make sure to test your implementation thoroughly and handle all possible scenarios, such as expired codes, to provide a secure and seamless experience for your users.
