Recently I have been troubleshooting a nasty Windows Hello for Business problem which prevented all users in a tenant from resetting their Windows Hello for Business PIN’s on Azure AD joined devices while getting the error CAA20004.

To do this in Windows 10, go to Settings and then Accounts. Select the entry for Sign-in Options. In the PIN section for Windows Hello, click the Change button (Figure A). If you’re tired of having to remember or reset your password, try using Windows Hello or a FIDO 2–compliant security key to sign in to your Microsoft account instead. All you’ll need is a device running Windows 10 Version 1809 or later and the Microsoft Edge browser.

The error indicates that an application registration is missing in the tenant for the application “Microsoft Pin Reset Client Production”

Solution

After a short search I found a matching Microsoft docs article. Instead of reading through the whole article the only thing I needed to do was consenthing to the: Microsoft PIN Reset Service production application and also for the Microsoft PIN Reset Client production

(just klick on the links in order to consent to the app registrations) as tenant admin. Although in some tenants I have only seen the “Microsoft PIN Reset Service production” and PIN resets are working without the “Microsoft PIN Reset Client production”.

When checking the registered enterprise applications in Azure AD the “Microsoft Pin Reset Client Production” was visible:

… and resetting Windows Hello for Business PIN’s is from now on possible and works like a charm.

Final words

Did you encounter the same difficulties? Or do you know why some tenants only have the “Microsoft PIN Reset Service production” and not the “Microsoft PIN Reset Client production” registered? I am curious to read your experiences in the comments.
