Admin lockout on Microsoft Authenticator after phone change.

Hello @RB

I understand that you are having trouble logging into the azure portal due to the authenticatior issues. If there is another admin, they can help you to reregister your MFA.

If you are the only admin in your tenant, this qualifies as a tenant lockout scenario. To resolve this, we need to engage the Data Protection team via a support ticket to unblock your access.

To proceed, I will need a few details from you. As this information contains Personally Identifiable Information (PII), please share the following details via private message:

• Contact phone number (add +Country code)
• Contact email address
• Global admin email address (affected account)
• Tenant Name
• Country
• Time Zone
• Tenant id/ Domain Name

Please send me the details via private message.

Thanks
