Hi all, 

I'm planning of running a closed Alpha for my game by limiting the access to distributed keys. However, I was wondering if it was possible to revoke access to said build after a certain amount of time. For example, I want my Alpha period to only last two weeks, and then after, prevent users from accessing.

If so, would it also be possible in later on to provide the same users new keys for a different build? Ie, I want to give a key to a user for access to a second beta test, even if that user was involved in the first.

Cheers!
