I have my personal outlook email id as Azure Login id, and since when Azure made 2FA compulsory, I setup the Authenticator App in my phone. (Remember I already had account setup with Microsoft Authenticator for my outlook id, now a new account setup for the Azure account in the Authenticator app) and I have lost access to that app now. However, I somehow got my outlook account authenticator app working in my new phone, but not having Azure account in it.
Now whenever I try to sign in to portal.azure.com it asks for the verification code, no other option.
What to do?
Additional context: The user is the only Global Administrator for their personal Azure account (personal learning purpose).
Lost accès to Azure Authenticator App
Re: Lost accès to Azure Authenticator App
**Because the Azure sign-in is protected only by Microsoft Authenticator and that method is no longer available on the current phone, the account's MFA registration must be reset from outside the locked account.**
### Solution for Single Global Administrator (Your Situation)
Since you are the only Global Administrator and this is the only admin account, this is a **tenant recovery case**:
1. **Contact Microsoft Support** via the Microsoft 365/Azure support channel (phone or web) using any account that can open a support request for the tenant (for example, the billing or original signup account).
2. **Clearly state:**
- The only Global Administrator is locked out due to lost Microsoft Authenticator
- No other MFA methods are configured
3. **What Microsoft will do:**
- The case will be escalated to the **Data Protection / Tenant Recovery** team
- They will verify tenant ownership (using contact details, billing, domain, etc.)
- They will reset MFA on your admin account so you can register a new Authenticator and configure additional methods
### After Access is Restored
Once you regain access, add **multiple MFA methods** to prevent this situation in the future:
- Microsoft Authenticator
- Phone number (SMS)
- Email verification
- Security key
