rminal name on which the last login was attempted.
nohost

  Don't indicate from which host the last login was attempted.

nowtmp

  Don't update the wtmp entry.

noupdate

  Don't update any file.

showfailed

  Display number of failed login attempts and the date of the last failed attempt from btmp. The date is not displayed when `nodate` is specified.

inactive=<days>

  This option is specific for the auth or account phase. It specifies the number of days after the last login of the user when the user will be locked out by the module. The default value is 90.

unlimited

  If the fsize limit is set, this option can be used to override it, preventing failures on systems with large UID values that lead lastlog to become a huge sparse file.

### 6.15.3. MODULE TYPES PROVIDED

The `auth` and `account` module type allows one to lock out users who did not login recently enough. The `session` module type is provided for displaying the information about the last login and/or updating the lastlog and wtmp files.

### 6.15.4. RETURN VALUES

PAM_SUCCESS

  Everything was successful.

PAM_SERVICE_ERR

  Internal service module error.

PAM_USER_UNKNOWN

  User not known.

PAM_AUTH_ERR

  User locked out in the auth or account phase due to inactivity.

PAM_IGNORE

  There was an error during reading the lastlog file in the auth or account phase and thus inactivity of the user cannot be determined.

### 6.15.5. EXAMPLES

Add the following line to `/etc/pam.d/login` to display the last login time of a user:

        session  required  pam_lastlog.so nowtmp

To reject users if they did not login during the previous 50 days the following line can be used:

        auth  required  pam_lastlog.so inactive=50
