Windows 10: Sudden PIN requirement

We have a 4-year old laptop. We have suddenly encountered a demand that we enter a PIN to access our computer upon start-up. We're relatively ignorant regarding tech so if someone could explain how to rectify this without a lot of technical jargon, we'd appreciate it.

Windows 10 not accepting PIN all of a sudden.....

Hi all,

Hope someone can assist....

My father's Windows 10 machine stopped accepting his PIN all of a sudden. There is no other sign-in option. I read that there's a way to get them back but since he only ever logs in with his PIN he has no idea what the password is (if any).

When clicking on forgot my PIN the email address listed is a really old one that he longer uses nor can get into. Started filling in the form to try and regain access but after Microsoft's verification it has been unsuccessful....

Is there any other way I can somehow fix it for him? Any help would be greatly appreciated.

Also why would this happen all of a sudden? He's been using the same PIN forever and it stopped working all of a sudden?

 

Clear "Pin suggested" list in People Bar

Does anybody know how to clear the "Pin suggested" list on the "People bar"?

Contacts are added to the "Pin suggested" list once you've pinned and unpinned them. But there seems to be no obvious way to remove them from that list.

After playing around with this feature and pinning and unpinning many dummy contacts, it's rather annoying to see them in the "Pin suggested" list when you click on the "My People" icon in the taskbar.
