Laravel 10.x Google 2FA Authentication Not Working

Dear user,

For a school project, I was following the following Tutorial and I run into one problem where I can't find the solution anywhere.

After I register the user, scanning the QR code he asks for an OTP password. I enter this code that was generated in the Authenticator, but still i get the message that the OTP is not valid while this is the code. I'm happy to show you the codes but they are identical to the tutorial. Please let me know if I need to show certain codes.

I hope someone can help me with this issue. Thank you in advance!

There could be a few reasons why the OTP code is not being accepted. Here are a few things to check:

Make sure the time on your server and your phone are synced. If the time is off by even a few seconds, the OTP code will not be accepted. You can use a time-syncing app like Google Authenticator to ensure that the time is synced.
Double-check that the secret key is being stored correctly in the database. You can check this by logging into your database and looking at the google2fa_secret field for the user in question. Make sure that the secret key matches the one that was generated by the QR code.
Check that the OTP code is being generated correctly. You can do this by logging into your server and running the following command:

php artisan tfa:generate

This will generate an OTP code that you can compare to the one generated by the Authenticator app. If they don't match, there may be an issue with the code generation algorithm.

Make sure that the OTP code is being entered correctly. Double-check that there are no typos or extra spaces in the code.

If none of these solutions work, please provide more information about your setup and any error messages that you are seeing.
