The TWiki Admin User has been added to TWiki 4.2.0 to make it possible to login without needing to create a TWiki User, or to temporarily login as TWiki Admin User, and then log back out to the same User and Group as before.
This means it is no longer necessary to add yourself to the TWiki Admin Group, and you will be able to quicky change to Admin (and back to your user) only when you need to.
