I've been using LastPass for years. Of course, there's no way to be completely safe using a cloud-based service and closed-source code, but so far they've conducted themselves in a trustworthy manner, and the system they've built has safeguards against remote security failures.
Their cross-platform support is great as well. The only thing that's missing is a solid way to retrieve passwords on Android. The LastPass "keyboard" is abysmal, and switching between their app and the one you want to enter the username/password in can be painful. I'm not sure if there's an easy way to solve this problem, though, given the sandboxed nature of mobile apps.
