And quite honestly I don't think that the bulk of our users have considered the privacy concerns or are aware that we've done things the hard way to protect their privacy. This is a lot more work than the easy way. So your lookup of some domain was only querying data on your own machine. So what we did was to create a very paired down version of the Watchtower database and deliver that whole thing to the clients. Even if we didn't log or record that information, we did not want that information transmitted to us. The problem with that is that we would learn the IP addresses of the users along with all of their websites. The easy (but privacy violating) way of doing so would have been to have a service that we host that 1Password clients would query with various URLs. We first introduced Watchtower before our service (we initially did it in response to Heartbleed). And so when we launched our service (needed to offer secure sharing features, fairer pricing, and more secure synching among other things), we wanted to keep the same principles, and so built the system so that we have as little information about you as possible. We, famously, bragged about not knowing anything about our customers. Whether they retain that information is a separate question, but such systems were receiving that information. This meant that the service operators not only had access to what sites and services a user had logins for, but they would even learn when the user looked up such items. Those may have been obfuscated, but they certainly weren't encrypted. As a consequence, systems of that nature would send unencrypted URLs to the password manager. Systems like LastPass faced the same problem of having to match items to user web pages and prevent a reasonable display of matches, but they stored data on their servers and queries were made that way. (With the introduction OPVault in late 2012.) This was so that the browser extension (which only talked to 1Password on your local machine) could query to find the appropriate item for the page it was on and to display titles for you before you entered your Master Password. As a consequence, from those early days, we had zero information about any 1Password user beyond a record of their license purchase if they purchased through us.Īt the same time, in these early days, our data format (Agile Keychain Format) did not encrypt things like item titles and URLs. 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. 1Password does not mix any element of the browser extension with the web interface.Watchtower does not present a URL (other than as saved by the user) for the user to change his password.1Password's extension does not have transmit any invertible encryption keys to the server.There is also an issue with the breach notifications that LastPass provide.įrankly I'm not bothered about the issues affecting LastPass because I'm a 1Password customer but I would like confirmation that: This has still not been rectified according to the author. Part of Wladimir Palant's evaluation showed that the browser extension requests your local encryption key which, if their servers were compromised, would comprehensively defeat the encryption. This is new research and not related to the extensively discussed (and sensationalised) ISE research. 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.
