sshd auth required pam_permission file=/etc/security/access.conffound=allow
sshd auth required pam_pmfa /etc/security/pmfa/pam_pmfa.conf

Check Contents

Verify SSH is configured to use multi factor authentication:

# grep ^sshd /etc/pam.conf | head -3

sshd auth required pam_ckfile
sshd auth required pam_permission file=/etc/security/access.conf found=allow
sshd auth required pam_pmfa /etc/security/pmfa/pam_pmfa.conf
