Something I've seen on other web-based gaming sites is the option to assign somebody as account sitter.
Within your settings, you would assign a player to sit your account. That player would then log into the site with your username, but their own account password.
And then they would have the ability to play your games as we do now when we ask somebody to log in as us.
But, the big thing is that the sitter never gets your password, and it's all official through the game itself.
