Hello @Lane Williams
Based on your description seems like you have been restricted to access resources.
In addition to the @Michele Ariis.
It's important to understand that the error message you're seeing doesn’t necessarily mean that someone has “hacked” your computer. Instead, it likely means that the machine you're trying to access is attempting to authenticate with an Entra ID service that has restricted permissions.
Here are some common causes that could explain this
1.If you're trying to sign in to a service or app (like Microsoft Teams, Office 365, or another Entra ID-integrated service), your account might be linked to an organization’s Entra ID system. It could be that you are trying to access something that’s controlled by a company or organization that uses Entra ID.
2.The administrator of the Entra ID tenant (msazurecloud.onmicrosoft.com) has placed restrictions on which accounts or users can access the tenant's resources. The error you're seeing indicates that your account is not authorized to access certain resources.
