NAME

       pam_google_authenticator - PAM module for two-step verification

SYNOPSIS

       pam_google_authenticator.so

CAVEATS

       The  current  version requires the existance of ~/.google-authenticator.  If the file does
       not exist for a user, the authentication module will fail.  Each user  MUST  create  their
       secret key with google-authenticator(1) PRIOR TO enabling this module.

       When used with sshd remember to edit sshd_config:
         ChallengeResponseAuthentication yes

EXAMPLES

       Add this line to /etc/pam.d/<FAVORITESERVICE>:

       auth required pam_google_authenticator.so

       If needed only for a certain group:

       auth [default=1 success=ignore] pam_succeed_if.so quiet user ingroup <group>

       auth required pam_google_authenticator.so
