I finally managed to convince my mother to start using LastPass recently; if I'd had to convince her to use two "master" passwords-- one for the encryption key, one for the service-- I'm fairly sure she'd still be using Google Contacts to store her secrets. :-\

Exactly. Why is why I entirely understand LastPass's reasoning for not doing that by default. But it would be a nice "advanced user" option (like 2F and all the other toys hidden in the account settings advanced tab).
