It seems to me (hence this question), that storing all your passwords online and accessing them with a single “unlock” password would be extremely dangerous. If the locker service is itself hacked, then the hackers will have ALL your passwords for the price of getting one password.

Why these are secure is somewhat complicated.
Firstly, the locker storing your passwords is no more secure than good security of passwords at your bank, or other best-practice following web apps. And…putting your password in the locker never makes it more secure than how it’s stored at some site. In fact, it ALWAYS makes it less secure – you’ve added a second vector for exploit, attack, poor management, etc.
What it IS more secure than is the real-world crap people do to keep track of passwords in a world that requires them to have so many. It’s more secure than having a cheat sheet on your computer, a post-it in your desk, a little note in your wallet. So…to understand the security of adding a second location for passwords – and one that stores all your important ones – you have to understand the alternative methods for storing lots of passwords.
If you can keep it all in your head, then that is more secure than a password locker.
