Processos no Microsoft 365 para configurar aplicativos do Office, resgatar chaves de produto e ativar licenças.
Hi NILTINSF,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
Based on your description, allow me to provide you with the information.
This issue is caused by a disconnection between the authenticator app data and the device that you register the MFA with.
To fix the issue, you can review these following methods:
Method 1:
If your bowser cache can still login to your account.
Go to mysignins.microsoft.com/security-info on your computer and sign in with your Entra ID.
- Select Add sign-in method.
- Select from the list of sign-in methods available and supported by your organization (authenticator app).
- Connect your new iPhone to the authenticator.
Method 2:
You can make a Temporally Admin account and reset the MFA on your primary account by following these instructions if you can still access Microsoft 365 Admin Center through the cache of your browser. As an alternative, you can follow the identical instructions below to request that the administrator reset your authentication method.
1 – Navigate to Microsoft 365 Admin Center, you can click Identity at the sidebar
Microsoft 365 Admin Center website: admin.microsoft.com
It will lead you to Microsoft Entra Admin Center (entra.microsoft.com)
Select Users
Click All users
Click on to the affected account name (your account)
For example
2 – Select "Authentication Methods"
3 – Click "Require re-register multifactor authentication"
Next time the user sign in, the system will require them to set up a new authentication method. By using this, the affected user can re-set up the right authentication method
In case if you are the only admin of your company, please reach out to our Global Customer Service phone to raise a request for resetting your authentication method: Customer service phone numbers - Microsoft Support
Please let me know if you have any questions or concerns in the meantime.
