My main concern is that I didn't see it in the Mac OS X App Store, which for me doesn't inspire confidence. If it can't make that cut, why should I or anyone else trust it with their passwords? I know its available for the iPhone and iPad via the App store, so why not the Mac OS X App Store? It looks good and I have seen favorable reviews, but what do you guys think? Do you like any other password managers better? Thanks! Update: I just went to LastPass' site to download and I see it's a browser extension, so I guess that's why it's not in the Mac OS X App Store. I then found it at Apple's Safari Extension Gallary. So my main concern has been addressed, but opinions and suggestions are still welcome!
