I can't access my student/business account

Question

I recently lost access to the device where I had Microsoft Authenticator installed and configured for my business account. With a new device in hand, I tried to configure this account again on this new device, and then the problems started. I can no longer access this account, either via the web (PC, laptop...), or through the app. In general, the steps I follow are:

*** The email address has been removed for privacy purposes ***

• I enter the password (which was also requested to be changed)

• and the message "Approve entry request" appears, along with the number that must be chosen in Microsoft Authenticator

But the code does not appear

Hi @Eduardo S.Ferreira

Thank you for posting your issue on Microsoft Q&A.

I understand that you are not receiving authenticator code when trying to sign in azure portal.

Microsoft authenticator code will be sent to old phone. To get authenticator code in new phone you should need to register account in new phone.

Contact your global administrator to Re-register MFA. Follow the below steps: 

1.Sign in to the Microsoft Entra admin center

2.Click on “Users” in the Microsoft Entra ID pane > Select the user.

3.In the user profile pane, select Authentication methods”. 

4.Look for the option “Require re-register MFA.” 

For more information: https://learn.microsoft.com/en-us/entra/identity/authentication/howto-mfa-userdevicesettings#manage-user-authentication-options

When you sign in again, user will be prompted to set up your MFA. Follow the prompts to add the Microsoft Authenticator app again in your new phone and sign in account you will receive code.
