Hello,
I've come across several methods that could prove helpful for you:
- You may resolve the issue by creating a local account first. Logged in with a local account and later linked to Microsoft account
- The absence of password synchronization between the machine and Microsoft account can be addressed by logging in once with the complete password on the remote computer.
- Try signing in with the full password of the Microsoft account at least once instead of using the PIN.
