Sole admin of tenant, have lost access to the authenticator app and unable to login azure portal


I created one tenant in azure account and using that for my work. I am the sole admin of that tenant. The only 2FA options I have to log in are via the authenticator app, which I now can't do. Even i am not able to change tenant for the subscription. Please help me to resolve this issue.

I created tenant other than default one. So dont able to switch to that directory. If I do it is directly going to 2fa authentication page.

Hi @NandhiniVelu-5229 · Welcome to QnA platform and thank you for reaching out.

The recommendation is to always keep break-glass admin account, by excluding one or more global admins so that you can revert the settings. However, if you forgot to keep a breakglass account, the only option is to open a support ticket to get Microsoft Data Protection team engaged for this issue. If you are unable to sign into your tenant, you can use any other tenant or signup for a new one to open a support ticket.

After providing required information and evidence to prove the company ownership on the subscription, they can help you with providing admin access to your tenant.
