Windows 8 – Use Windows Live ID but Login with a Different Password

Windows caches the password locally. This makes it possible to login without connection.
Would you be happy if Windows doesn't allow you to login and use your computer when you have no Wi-Fi connection?

It will deny login if the passwords do not match.

I guess it works similar to domain logons: if the domain controller is not available but the entered password matches the locally stored one, Windows allows logon. Even more, Windows does not contact the domain controller right away if the cached password matches, but it will validate the password on the domain if it doesn't, in case you changed it.

Of course, you have to be connected when you log in for the first time.

I've found a couple of options, neither ideal:

1. Use a picture password
2. Use a PIN

Frustratingly, PINs are limited to 4 digits. It's a shame (in my opinion) that Microsoft didn't add a 'Use a simple password' option too for exactly my scenario - but I assume that having two passwords would be too confusing.
