This leaves the accounts in an 'out-of-sync' state where the local user account still accepts the old password until the Microsoft account, not the pin or picture password, is used to log in to the system locally. If the user then switches to using a pin or picture password at the local console, the credentials do not get updated locally, even if the user changes the password on the Microsoft website, the 'Manage Microsoft Account' link in Settings, or the 'Change Password' utility in Sign-in Options. What is happening: When a Microsoft account is linked to a user account in Windows 10, the credentials are cached locally to facilitate offline logins. This can happen even if the user changes the password on the Microsoft site. This happens when users only use a pin or picture password when logging in at the local console. When using Remote Desktop on Windows 10 and using a Microsoft account to authenticate, the login will sometimes fail if the credentials have not been updated locally.
