Authenticator & Git Hub

Hi everyone,

While signing up / managing authentication on Microsoft properties, I noticed an option connecting to a GitHub organization/account named ⁠Microsoft-corp⁠ rather than the official ⁠Microsoft⁠ organization.

Upon checking, the ⁠Microsoft-corp⁠ profile on GitHub has very few followers and looks distinctly different from the primary ⁠microsoft⁠ GitHub organization.

A couple of questions for the community or team:

  1. Is ⁠Microsoft-corp⁠ an internal/legacy OAuth app or enterprise tenant placeholder managed by Microsoft?
  2. Or is this an unauthorized/spoofed GitHub organization attempting to masquerade during third-party auth flows?

If anyone from the Microsoft team or community security folks can clarify whether this identity is legitimate, it would be greatly appreciated!
