We started out as purely local (and supporting using handling their own synching via a third party such as Dropbox). Many of the differences between how 1Password works and (my limited understanding of) how LastPass works arise from our very different histories. I have not carefully analyzed LastPass's behavior. Everything I might say about them could be mistaken. (See further below for where web-apps are used in perhaps surprising places.) Longer answersĭisclaimer: First, I need to disclaim any expertise or authority in speaking about LastPass's security architecture and specifics. 1Password does not mix any element of the browser extension with the web interface.Ĭonfirmed for our browser extensions.

The most serious flaws, allowing the encryption to be subverted, have now been fixed.

I came across this blog post in which the author discusses a vulnerability in the LastPass.
