Tenant Lockout – Sole Global Admin locked out due to MFA, requesting Data Protection Team escalation

I am locked out of my account. My Authenticator account was producing errors, and I unfortunately did not plan a backup MFA beyond the app and code (which both require Authenticator working). I incorrectly deleted the Authenticator account, thinking that adding it back would solve the problem. I am the sole global administrator.

I am now in a loop where I need to be logged in to set up Authenticator and need Authenticator to be logged in. I called support and fairly quickly had a case number assigned (26<removed PII>).

I was placed in a queue to speak with the Data Protection Team, and waited eleven hours before disconnecting. I communicated via X and also talked to a front line person today that both said waiting for the data protection team is the fastest access to my account. I have now been on hold for that team almost 13 hours today. In total I am over 26 hours on hold -- clearly this approach isn't working.

How do I get back into my account?

Thank you,

Guy Blanchard
