Hello Paloma,
I have similar situation. I just get a new computer with Win 11 21H2 installed (OEM). I want to use only my Windows Account password, no PIN, no face recgonition, but the login still asking me to create a face "Hello, and if I choose to skip it, Win 11 ask me to create a PIN, so I close that window and I can finilly login, but on next login, everthing comes back.
I try what you propose above, but I couldn't find the item 4 - "Require Windows Hello Sign In for Microsoft Accounts"
Thank you in advance.
Regards,
Guy
