Lost access to Authenticator app and can’t reset password

@Sridevi Machavarapu Thanks for such a prompt response! I have multiple issues to detail.my password to this account I am logged on on will expire in 9 days. If tried resetting but the Authenticator app does not receive or generate the required codes. That’s the only option I have as admin for 365 business did not add my mobile

Our company admin has left the business and we now have no access to the admin accounts. That is also a problem as we can’t reset the password that way.

i believe I need to contact the data protection team to get you some evidence etc.:.. I have tried over the phone but just get stuck in a loop. Can you help me access the admin and reset my password? The password is most pressing due to the timescales imposed. Thanks

    Hello Dougie McGill,

    Thanks for sharing the requested details in Private messages tab.

    The issue pertains to a tenant lockout, where no other global admin in the tenant has the necessary permissions to login and make changes in your tenant.

    To resolve this, we have engaged our Data Protection team through a support ticket. They will reach out to you via email or phone to help restore access to the tenant and assist in resolving the issue.
