How to Fix Missing QR Code for Microsoft Authenticator Setup
Question details
The user is unable to generate or view the QR code required to set up Microsoft Authenticator, preventing them from securely logging into their account.
- Product
- Microsoft 365 / Microsoft Authenticator
- Device & OS
- not provided
- Scenario
- Attempting to set up Microsoft Authenticator for multifactor authentication but experiencing a sign-in verification loop.
- Observed behavior
- The sign-in verification loops endlessly after selecting an alternative sign-in method. Microsoft Authenticator fails to add the account, and the expected QR code does not display, even when multifactor authentication appears disabled.
Determine whether you are using a Microsoft 365 Business/Education account or a personal Microsoft account, as the recovery steps differ significantly based on the account type.
Request an Authentication Reset from Your Administrator
This is the best solution for users on a Microsoft 365 business or school account who are locked out of their MFA setup.
If you are using a work or school account, your organization's IT administrator controls your multifactor authentication settings. You will need their assistance to clear your old MFA sessions and force the system to generate a new QR code.
Reach out to your organization's IT administrator or internal helpdesk support team.
Ask the administrator to navigate to the Azure Active Directory (Entra ID) admin center, locate your user profile, and click 'Require re-register MFA' for your account.
Once the admin has cleared your old authentication methods, sign in to your Microsoft 365 account on a computer. You will be prompted to provide more information, and the new setup QR code will be displayed.
Contact Microsoft Support for Sole Administrators
Use this method if you are the only global administrator for your organization's Microsoft 365 tenant and are locked out by the verification loop.
Troubleshoot Personal Accounts via Microsoft Support
If you are using a personal Microsoft account (such as Outlook.com or Xbox), use the official recovery resources and community guides.

Frequently Asked Questions
Why is Microsoft Authenticator looping without showing a QR code?
This usually happens when an older authentication method is stuck in the system cache, or when another sign-in method conflicts with your MFA setup. For business accounts, your IT administrator must clear the old methods to force the system to generate a new QR code.
Can I set up Microsoft Authenticator without scanning a QR code?
Yes. If the QR code is missing or cannot be scanned, you can manually enter a 9-digit code and a specific URL provided by your organization on the Authenticator app's setup screen to link it to your account.
What should I do if I am the only administrator and get locked out by an MFA loop?
If you are the sole global administrator for your Microsoft 365 tenant and get locked out, you cannot reset it yourself. You must contact the Microsoft Data Protection support team by phone to verify your identity and have them manually reset the MFA requirement for your tenant.
