Lost my Office 365 Developer Tenant admin account due to MFA and lost authenticator app

Copper Contributor



I have lost my authenticator app which used to hold the mfa for my o365 developer subscription administrator account. This was the only admin for the tenant, and whenever I try to sign in or add the admin account to another authenticator app, it asks for a response from the old authenticator app (which I don't have)


what can I do? Can I create another admin from somewhere? I can see my subscription and the admin account on my developer dashboard, but I have no option to the change the admin account


Thanks for your help
