Best practices: retaining control of the Google accounts which manage your Android Enterprise organisation

Hello Lizzy,

The provided solutions and best practices doesn't work:

• Additional account owners/admin .

After adding a second owner/ admin and inviting him, the second admin is asked for creating a Google account and at the last step the error message "Something went wrong, try again" appears.
We have tried this with multiple MPS accounts on different browsers/ computers/ networks and are facing the same error message, over and over again.

• Stay informed with notifications: add a recovery email or contact information to your Google Account(s), so you are notified of any changes with your account.

Adding recovery emails doesn't prevent anything. We have our IT Supportdesk email added as recovery email address to all our customers Google accounts but never got a warning.
Only the final e-mail that's informing the account has been deleted due to violating of terms!

• 2-step verification: add an additional layer of security to your account.
I don't get in what way this step will prevent Google accounts from getting deleted? Besides that, Google limits the number of accounts that can be verified with a single phone number. It's not realistic to ask IT Organizations who are managing different MPS accounts for their customers,to use dozens of different phone numbers for 2-step verification.
