pam_wtmpdb

PAM module to record login and logout times of users

pam_wtmpdb.so [debug] [silent] [skip_if=<services>] [database=<file>]

pam_wtmpdb is a PAM module to record the login and logout information of the user. The module uses /var/log/wtmp.db as database file to store all information.

Compared to some wtmp(5) implementations this PAM module is Y2038 safe and uses sqlite3 to store the information.
