How can I get support with my Azure account log in?

Hi everyone,

I have a personal Azure account, but I'm currently unable to sign in. I've been passed around several times by Microsoft chat agents and am still looking for guidance.

When signing into Azure, I receive the message:

More information required

Your organization needs more information to keep your account secure. Before making changes to your security info you must complete multifactor authentication.

I click Next and then receive:

You are required to register an authentication method to continue but none have been enabled for this account. Contact your admin for help

I'm not part of an "organization" - I'm the sole admin and user in my Azure subscription, and I have two-factor authentication enabled for my Microsoft Account, and I have passkey enabled. I must have made a mistake somewhere when multifactor authentication became required in Azure, but I can't get into Azure/Entra to figure out what it is, and I can't submit an Azure Support ticket without being able to sign into Azure.

I've tried talking to Microsoft support, but they keep referring me to Azure Sales. I know technical support is only available for non-consumers. This doesn't seem like a technical question with Azure, I've screwed something up login-wise as the Admin of my own subscription and can't get in.

Anyone have any ideas how I can move forward?
