Documentation mentions editing files such as /etc/pam.d/gdm for the u2f module. However, Fedora 42 seems to have a split configuration for gdm. Files appear in /etc/pam.d as:

• gdm-autologin
• gdm-fingerprint
• gdm-launch-environment
• gdm-password
• gdm-smartcard

Could the directions be clarified to indicate which one is appropriate for the yubikey u2f usage?
