Windows Hello for business ask a Microsoft account

Hi,

I have an active directory on Windows server 2016.

I tried to setup Windows hello for business on my clients whth these GPO :

• Use Windows Hello for Business
• Use certificate for on-premises authentication

Windows Hello is then available on clients.

But when i setup a Hello PIN code, it ask a microsoft account.

On another AD in my enterprise it dosen't ask for MS account with the same GPO and i don't get how to replicate this.

Have you an idea ?

Thanks
