Fix Recommendation

Configure Ubuntu 24.04 LTS to use multifactor authentication for access to accounts.

Add or update "pam_pkcs11.so" in "/etc/pam.d/common-auth" to match the following line:

auth [success=2 default=ignore] pam_pkcs11.so

Check Contents

Verify that the "pam_pkcs11.so" module is configured with the following command:

$ grep -r pam_pkcs11.so /etc/pam.d/common-auth
auth [success=2 default=ignore] pam_pkcs11.so

If the module is not configured, is missing, or commented out, this is a finding.
