Greetings, Henry S. Thompson!

> Running cygwin 3.2.0-1 on Windows 10 Pro 21H1

> Since changing my login from local User to Windows Hello PIN, I can't
> ssh in to my machine using a password:  neither the PIN nor my old
> password work:

>   1) If from my machine I do
>           ssh -o PreferredAuthentications=password localhost
>      or
>           ssh -o PreferredAuthentications=password [me]@[host]
>      or
>           ssh -o PreferredAuthentications=password U-[HOST]\\[me]@[host]

>      I get "permission denied".

>   2) If I try any of those from another machine, it hangs (but works
>      w/o the "-o PreferredAuthentications=password", i.e. using a
>      key).  By 'hangs' I mean that having typed the PIN and Enter,
>      nothing happens, including no output if I include -v -v -v.

>      Weirder still, if I try using strace, communication happens and I
>      get "permission denied"

> I have reinstalled openssh, removed the cygsshd service, re-run
> ssh-host-config and restarted the service to no avail.

> I only need password login to install new keys, and obviously there
> are workarounds for that, but if there's just something I'm missing
> I'd like to fix it.

> Are there other things I need to worry about having switched to using
> a PIN?

Did you try to `passwd -R` as explained in
https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-setuid-overview ?
