The PAM 2FA module provides a second factor authentication, which can be combined with the standard PAM-based password authentication to ask for:
pam_ssh_user_auth checks the value of SSH_AUTH_INFO_0 and will return success if is non-empty and failure if it is. It can be used to skip other PAM authentication methods with a configuration like:
auth [success=1 ignore=ignore default=die] pam_ssh_user_auth.so
auth substack password-auth
