If I log in using my personal computer and choose [Remember password], but one day I'm using a public computer so I have to use [Log out] before leaving, my "password" saved on my personal computer is forgotten and I have to log in again.
This works correctly in MediaWiki, but CentralAuth removes MediaWiki's token and changes its token on logout, so it invalidates other sessions.
