LastPass is cheaper at $1 per month (you'll have to pay this if you want access on your mobile, otherwise it too is free) which provides access on just about any OS you want (complete with browser extensions).The software is polished, syncs automatically via Dropbox or iCloud and uses openSSL to encrypt its data.

1Password is relatively expensive, and you'll have to pay a separate fee per platform starting at $17.99 for the iOS version, and $49.99 for the Mac version.

That's not to say it's insecure, but one as one commenter on this LastPass blog entry put it: 'If an enemy knew everything but the password, you system should still be just as secure.' Because there's no source code to dismantle and test, there's no telling quite how secure LastPass really is.

What worries many is proprietary encryption, such as that used by LastPass. 1Password also uses open source (SSL) encryption, so it too is considered transparently secure. KeePass is open source, which means that its security algorithms have stood the test of time so far – if you want to break it, go ahead and give it a go. There are alternatives to LastPass, 1Password and KeePass, but these three are arguably the most popular solutions on the market. Using KeePassX, which itself is removed from the official KeePass project, isn't exactly 'risky' though. Using a paid alternative to KeePass will afford you better compatibility with various devices, more polish when it comes to software and (in some cases) support when things go wrong.
