Why is the xbox app asking for a pin when I try to log onto it with a new device?

Hi RhysHow! My name is Ricardo an independent advisor ready to help you with this situation!

Could you please share a screenshot of the pin request, to confirm which pin is being asked

Usually what you get requested is a verification code that you will receive on the email you have set as contact method or on the Microsoft authenticator app

Hi, thank you for the advice but it specifically is not asking for an Xbox pin, and will not let me enter more than four digits when prompted for my non-existent pin. Whenever it says my pin is incorrect, it explicitly tells me to change my pin through Windows Hello. Everything that is going on here is all on Windows computers. No consoles are involved. I can't get a screenshot at the moment as the computer that's been having the error is currently in use and I cannot get access to it, I will edit this post or reply to it with a screenshot when I am able to get to it. A quick rundown of the situation is as follows:

There are two computers upstairs, one with Gamepass Ultimate, one without

We are trying to put the Gamepass Ultimate account onto the computer that does not have it.

When trying to sign in, the Xbox PC app asks for a Windows Hello Pin that does not exist

There is no possible way to bypass this pin, and no pins work, as no pin exists.

We try logging a different account onto the computer, it asks for another pin that does not exist.

App thinks its a dictionary attack and locks us out of the Xbox PC app

We just want to get my account onto a new computer, that's all we want, but it's asking for login info that doesn't exist

When it asks for a pin is this because it is trying to set up "Windows Hello"? If so I have this issue where logging into my work device with the Xbox App it tries to setup Windows Hello and askes for my PIN which is rejected despite it being correct.
The irony is my work device doesn't support windows hello. So far been unable to get it working

So, I figured it out ...

When logging in to the XBox app on the family laptop, it did the following:

Asked for MY XBox/Microsoft login (not associated with laptop)

Asked for MY password (not associated with laptop)

Asked for PIN (which I assumed was MY PIN, since it's MY account)

On a whim, we tried using my child's PIN who was logged into Windows on the Laptop.

It worked.

IMHO, this is a horrible system. Why would an app ask for login information multiple times for 1 person associated with an APP, but have the last item needed be the login info for a 1 person associated with a OS, and then NOT tell you what it's actually asking for? Who in their right mind would assume that after TWO prompts for info that it would be a THIRD prompt for somebody ELSE?

Ridiculous.

Thank you, Lucas, for trying to help.

I was able to resolve this issue by logging onto my Xbox 360 and deleting pins. They were maxed out at 200. Deleted all pins and now I can pin from anywhere including the console and Xbox app.
