pam_timestamp - Authenticate using cached successful authentication attempts
pam_timestamp.so [timestamp_timeout=number] [verbose] [debug]
In a nutshell, pam_timestamp caches successful authentication attempts, and allows you to
use a recent successful attempt as the basis for authentication. This is similar mechanism
which is used in sudo.
When an application opens a session using pam_timestamp, a timestamp file is created in
the timestampdir directory for the user. When an application attempts to authenticate the
user, a pam_timestamp will treat a sufficiently recent timestamp file as grounds for
How long should pam_timestamp treat timestamp as valid after their last modification
date (in seconds). Default is 300 seconds.
Attempt to inform the user when access is granted.
Turns on debugging messages sent to syslog(3).
