otk key meaning about tcexam HOT 2 CLOSED

Please note that the OTP Key is not present on the user registration page but on the user administration page.
This key is automatically assigned to a user during the registration if the constant K_OTP_LOGIN on shared/config/tce_config.php is set to true.

When this constant is set to true, TCExam uses a 2-step verification process that requires you to enter two pieces of information before you can access the system. The required information is the standard TCExam password and the verification code generated by your smartphone. This prevents hackers from accessing your account if they only have your password or phone. However, it also means that you will always need to have your phone at hand whenever you want to login to your TCExam Account. To use this system you must download and install the Google Authenticator app on your smartphone.
