Problems Logging In Due to Multi-Factor Authentication

[Vincent_Rothlaender]

At the moment, I am unable to log in to Azure with my account (Global Administrator). Although I am also a Microsoft Partner and have 10 credits for support requests, I cannot create a support request here. Therefore, I have to post in this forum. I can log in to Office 365, PowerApps, Power Automate, and other services with MFA without any issues. However, when I log in to portal.azure.com, I am prompted for authentication again immediately after logging in, and I cannot proceed further from there.

I have created two tickets with Office 365 and Microsoft Entra ID, but neither ticket has successfully resolved the issue. Here is what we have tried so far:

1. Disabled MFA, but MFA still appears.
2. Successfully removed my guest account from other organizations.

The problem still persists. What can I do here? Can Microsoft Azure contact me since I still have 10 credits?

See whether this can help:

I faced a similar issue where I couldn't log in to Azure due to MFA, despite accessing other Microsoft services without problems. I wanted to share what worked and what to check if you're facing the same issue.

• Check Conditional Access Policies: Make sure no policies are forcing MFA in Azure AD > Security > Conditional Access.
• Verify MFA Status - Ensure MFA is fully disabled in Azure AD or using PowerShell:
  Get-MsolUser -UserPrincipalName email address removed for privacy reasons | Select-Object DisplayName,UserPrincipalName,@{Name="StrongAuthenticationRequirements";Expression={$_.StrongAuthenticationRequirements}}
• Clear Browser Cache - Try clearing cache or using incognito mode.
• Guest Accounts - Remove external guest accounts from other organizations.
• Security Defaults - Check if Security Defaults are enabled in Azure AD and consider disabling them.
• Use PowerShell/CLI - Log in using Azure CLI or PowerShell with:
  az login
• Leverage Partner Support - Use your Partner Center credits to raise a support ticket or contact Microsoft directly for help.

Thank you, I have already tried this with both Microsoft supports. I think I have found the cause, but I can no longer solve it. Yes, I have 10 credits from Microsoft, but I somehow can't redeem them to get support. The possible cause is that I have two tenants in the Azure Portal. There is a default directory that I can no longer access. My global account with Vincent is also there, and at the moment I can only work with a current tenant. As soon as I try to switch to the default directory, I can no longer get in. I also tried with az and I can't access my tenant.

Please try these, this should help you to narrow down the issue.

• Check Tenant Access - Ensure you have the right permissions in your default directory. If possible, contact someone with admin access to regain entry.
• Use Azure CLI - If you can access the CLI, try logging in with the command:
  az login --tenant <your-tenant-id>
  This may help you switch tenants.
• Access with Another Account - If you have access to another account that can access the default directory, use that account to check permissions.
• Check Subscription Eligibility - Ensure your current subscription is eligible for support credits.
• Contact Microsoft Support - If you can’t redeem your credits, reach out to Microsoft Support directly. Explain your situation about having multiple tenants, and they might assist you in transferring credits.
