Seems like Microsoft doesn't like to pay for a bug bounty

I agree that it's weird that they fixed it and didn't consider it a security issue.

For the user it looked like it would provide two-factor authentication since the PIN is requested, while in reality it's not verified. Thus, they only provided one-factor security.
