Consider the following scenario:
- You're a global admin who has Microsoft Azure AD Multi-Factor Authentication (MFA) enabled
- You don't receive the text message or voice call that contains your verification code.
In this scenario, you can't sign in to your work or school account, such as Office 365, Azure, or Microsoft Intune.
To fix this problem, follow these steps:
- If you have set up other options for security verification, select Other verification options, and then try again by selecting a different option. Also, make sure that your phone numbers are correct in your user account settings.
- Ask another global admin to confirm whether your phone numbers are set correctly in your user settings.
If steps 1 and 2 don't resolve the problem, your user account may be blocked from using Azure AD MFA. To check whether your user account is blocked, ask a global admin for your Microsoft cloud service to perform the following steps:
If you have an Azure AD MFA or Azure Active Directory Premium subscription
- Go to the Azure portal, and then open Azure Active Directory.
- If you want to change the default active directory, click Manage tenants, choose the active directory, and then click Switch.
- Choose Users, open the profile of the user that has the problem.
- Check whether the Block sign in is enabled. If yes, disable the option.
If you have Office 365 and don't have an Azure AD MFA or Azure Active Directory Premium subscription, contact Office 365 Support.
