I'm working in a free trial account.
I've created a user in the default directory and made that user a co-administrator. I want to login to Azure with those credentials (so I can change the temporary password, for one thing) but I don't know how to do this. The id I want to login with looks like aadadmin@myLiveAccount.onmicrosoft.com.
I can't find a way to login to my Azure subscription with anything but my Live account.
Surely this question is low-hanging fruit for someone out there.
