Other Intune-related topics, including unsupported scenarios and platform-specific behaviors
@Chris Pothecary Thanks for posting in our Q&A.
For our issue, I have done some tests, the result shows that after changing the PIN length in the Windows Hello policy, existing users who have logged in can be worked normally, but the next time i log in, it will be prompted that the login failed and the password needs to be reset.
Hope it can help.
