If anyone else uses your computer and you care if they can connect using your password, then just enter it each time. If it doesn't matter if they connect using your password, or no one uses your computer, then it doesn't really matter. Just don't use a password that matches important passwords such as passwords to bank accounts. As long as the password is only for the network(s), then it probably doesn't even matter that much if someone else uses it unless they decide to try to get you banned.
