You can also add in KeepassHttp + PassIFox. But I wonder if these might have similar vulnerabilities as they too would be handling decrypted passwords.
I've been looking for a alternative with somewhat parity with lastpass with a better security policy.
Cons: NOT open-source, paid cellphone apps.
So a slew is not necessarily accurate. But I take you're point, it's definitely a similar weak point that LastPass has.
