How to Fix Power BI Sign-In Loop After Losing Microsoft Authenticator Access
Question details
The user is trapped in an infinite sign-in loop when trying to log into Power BI because they lost access to the Microsoft Authenticator app after resetting their phone, with no backup codes available.
- Product
- Microsoft Power BI
- Device & OS
- not provided
- Scenario
- Attempting to log into a Power BI account as the sole Global Administrator without Microsoft Authenticator access or alternative verification methods.
- Observed behavior
- The sign-in process repeatedly prompts for authenticator app approval, causing a loop that entirely blocks access to the account.
Double-check if there is another Global Administrator within your organization's tenant who can easily reset your multi-factor authentication (MFA) settings from the Azure portal before you proceed.
Contact Microsoft Phone Support for Tenant Access Recovery
Because you are the sole Global Administrator and have no backup codes, you must work directly with Microsoft's Data Protection Team to verify your identity and restore access securely.
Since this issue involves sensitive organizational security and tenant access, it cannot be resolved through public forums or self-service password resets. Microsoft requires strict verification to protect your organization's data.
Visit the official Microsoft Support website and locate the customer service telephone number specific to your country or region.
Call the support line and explicitly request the representative to create a service request for a 'Global Administrator account lockout' and an 'MFA reset'.
Wait for the Microsoft Data Protection Team to contact you through a private, secure channel. You will need to provide proof of domain ownership, such as billing details or DNS records, to regain access.

Frequently Asked Questions
Can I reset my Microsoft Authenticator app without my old phone?
If you are a standard user, you can ask your IT administrator to require re-registration for MFA on your account. If you are the only Global Administrator, you cannot reset it yourself and must contact Microsoft Support.
Why am I stuck in a sign-in loop even with the correct password?
The loop occurs because Azure Active Directory strictly requires MFA approval for your account level. Since the Authenticator app is unavailable, the system fails to advance past the secondary authentication prompt, looping back to the start.
Are there backup alternatives to using Microsoft Authenticator for Power BI?
Yes, administrators can configure alternative MFA methods in Azure Active Directory, such as SMS text messages, phone call verification, or hardware security keys (FIDO2), to prevent future lockouts.
How long does it take for Microsoft Data Protection to unlock an admin account?
Depending on the complexity of verifying your identity and domain ownership, the process can take anywhere from a few days to a couple of weeks. Microsoft prioritizes security over speed in these scenarios.
