Matthew,
This doesn't actually answer the question.
I, too, am getting MSAA auth request (on my iPhone) but I have removed the accounts they belong as I worked as a consultant for many orgs. Now my account is being used by one of them, and I need to find out which one. There is no logging onto any tenants, I need to find out the Tenant from my iPhone.
