My friend is trying to transfer over from monolith to Soe but he can't find his master account name and password to transfer it over. Is there anyway he can get it form Monolith?

Vaico,

 

He can contact our support as we can assist with password recovery, if he doesn't know his user name however they aren't going to be able to help much.
