pam_rps(8) -- Linux man page
NAMEpam_rps - challenge-response authentication
SYNOPSISauth sufficient pam_rps.so
DESCRIPTIONpam_rps.so is designed to provide a true challenge-response authentication mechanism for PAM-enabled applications.
Without pam_rps, successful authentication can only occur for a user if the user has previously established an authentication token for use with the server. Using pam_rps removes this limitation.
- Enable module debugging. The module will log its progress to syslog.
The challenge issued to the user is derived from a random number. This
argument allows the administrator to control which challenge will be presented
to the user. This argument is meant for use only when debugging.
NOTESNever use this module.
