This is why I prefer to keep my passwords in an offline password manager, namely KeePassX.
I think this discussion came up once before, and Scott Schmitt asked me why I thought KeePass was better than LastPass — I didn’t have an example to point to at the time, but this is why. The fewer people that can even see my database file, let alone decrypt it, the better I feel about it.
Adoption of poorly secured password managers opens a single point of failure.
