I received a question from a customer asking me for a way to create MFA-enabled administrator accounts on all Microsoft 365 tenants managed through the Partner portal, without having to manually go to each tenant and creating them. To solve this, I threw together a quick script that imports a .CSV file containing the DisplayName, UserPrincipalName and Password and then goes through every managed tenant to create the accounts and enables MFA on the newly created accounts.

As an extra bonus, I’ve also provided a script that could be used to remove the accounts on all managed tenants.

Enjoy!
