The "required" control value in the /etc/pam.d/sshd file or any PAM (Pluggable Authentication Modules) configuration means that the module must succeed for authentication to proceed. However, even if a "required" module fails, the rest of the modules in the stack will still be processed, but ultimately, the authentication will fail. This allows for all modules to be checked, which can be useful for logging all failures.
