Chrome has built in syncing. Options for setup are in the options panel, at the top of the "personal stuff" tab.

I didn't know about it, it's really great. It's sort of a synchronized keepass with better browser integration. Thanks.

I use Roboform--it's cross platform/cross browser. Works well. Not free, however, if you have a lot of passwords (most geeks will cross into their paid territory pretty fast.)
