The number of days that a user's password is good for.
After this number of days, the user will be prompted to change their password every time they log in.
After an additional period defined by
$wgPasswordExpireGrace, the user will be forced to change their password the next time they log in.
This setting is false by default, meaning that passwords do not expire.
