Maybe call this ...Fragment? (You could shorten "Reauthentication" to "Reauth"
or something if the class name becomes unwieldy).

Done.

hahaha, sorry, used that to test something and forgot to remove

Add a Javadoc comment. It would also make sense to rename this to be more
descriptive in what the actual effect is, i.e. something like
preventLockingForTesting().

[dozsa, 2016/08/17 10:40:27]

Done.
