What are the potential security risks of integrating Fido2 login into a PHP script?

One potential security risk of integrating Fido2 login into a PHP script is the possibility of exposing sensitive user data if the authentication process is not properly secured. To mitigate this risk, it is important to ensure that the Fido2 authentication process is implemented securely by using HTTPS to encrypt communication between the client and server, validating user input to prevent injection attacks, and securely storing user credentials.
