When you sign in to 1Password, your information is further protected by a unique communication system that ensures neither your account password nor Secret Key are ever sent over the network. End-to-end encryption keeps your information safe And, like your account password, your Secret Key is never sent to our servers. Secret Keys are impossible to guess they’re generated from a range of 2^128 possibilities. Only you possess it, and it’s stored solely on the devices you choose. The Secret Key is an account-specific, 26 character, 128-bit strong encryption ingredient generated on your device when you first create your account. You don’t need to memorize this key, nor do you need to enter it every time you unlock a trusted device. When you sign in to 1Password on a new device, you’ll also need your Secret Key. No matter how you create it, your account password is never visible to us. Plus, suggested passwords are generated entirely on your device. Suggestions are drawn from a pool of 18,000 words, so a four-word suggested password is one of about 100 million billion possible combinations. If you need inspiration, you can use our password generator when you set up your account. Make sure to use something long, unique, and memorable. Your account password is the only one you need to remember. Only the encrypted vault data lives on our servers, so neither 1Password nor an attacker who somehow manages to guess or steal your account password would be able to access your vaults – or what’s inside them. The two are combined on-device to encrypt your vault data and are never sent to 1Password. Only you know your account password, and your Secret Key is generated locally during setup. Three things are needed to decrypt your information: the encrypted data itself, your account password, and your Secret Key. Here’s why your information is safe in 1Password, and why you don’t need to worry about your passwords being exposed if our servers were to be attacked. In fact, it’s a question we asked ourselves when we designed 1Password’s security model. So a question like, “What happens if 1Password gets hacked?” is completely reasonable. You trust us with some of your most valuable data: confidential logins, bank information, secure notes, and more. You don’t need to share secrets to confirm your identity ContentsĮnd-to-end encryption keeps your information safe But even if it was, we’ve designed our systems to make sure your passwords and information would still be safe. Those are very different threat models, and always worth assessing them separately.ĭisclaimer: I've been a long time user of 1Password, but the recent breaches indeed got me a bit worried about what would happen if AgileBits were ever in the same situation.We’ve been protecting our customers' data for over fifteen years, and in all that time 1Password has never been hacked. The last paragraph is also great: the point of longer passwords is not as much to protect from a breach on their side, but to protect in case your own machine is breached*. It also made me appreciate even more 1Password's architecture, and a deeper understanding of the (mildly annoying) secret keys. I think the article also does a good job explaining why the claim that " you're safe because of 100,100 iterations of PBKDF2" is pure marketing BS, and LastPass is either being dishonest or intentionally misleading users. This means that using a combination of rules and dictionary-based attacks could indeed significantly reduce the search space. However, if you were able to breach LastPass and got a database containing hundreds of thousands or millions of users, you could safely assume that many would have average-length passwords, with lower entropy than machine-generated passwords. If you are an attacker and targeting a specific user, then yes - you wouldn't know the password length.
