[help] Locked out of M365 admin account - Authenticator not working after switching to new iPhone - Microsoft support not responding
I got a new iPhone yesterday and my Microsoft Authenticator app stopped working. I am now completely locked out of my Microsoft 365 account and cannot access email, SharePoint, or Power Automate.
I am the sole admin of my tenant and the only employee of my business. Everything is shut down until this is resolved.
What I've tried:
- Reinstalled Authenticator
- Tried all alternate sign-in options — none registered
- Accessed Entra admin center and clicked "Require re-register MFA" and "Revoke sessions" — this locked me out of Entra too
- Submitted Microsoft support ticket (2605180010000159) last night with no response
- Sent two escalation emails with no response
Is there any way to escalate this or a direct contact at Microsoft who can help? Or any workaround I'm missing?
