And with a 20 character we're looking at a universe of passwords about 14 million times (62 x 62 x 62 x 62) larger. For just 16 characters you could give every person on earth a billion passwords and still have enough unique passwords left over to do this a billion more times. I recently played with some math for passwords of 16 characters and the exponential nature makes things get crazy big incredibly fast. If a website requires a short password, we don't want to remember the attributes required by that site.Īnother way to look at this is there are attributes, not preferences, so we default to what's best for this website.īy the way, the amount of entropy in a random 20 character password with mixed case and numbers is incredibly high. I expect many people will crank the password length up to 50 and if we preserved that we would run the very real risk of passwords being created that would appear to work and then stop working in the future. We've seen many websites silently truncate longer passwords to make them fit within their database, which leads to lots of confusion as passwords that work in one place won't work in others. For the random character based passwords we went with a length of 20 as it was a great balance between security and website compatibility. We made the conscious decision to always default to what we believe is the best possible password for most situations. You're right, we don't restore password attributes after they have been changed. It was a lot of fun to create but seeing folks using it is even more so. I'm glad to see you playing with our new password generator. More from Dave (one of our founders) on this: We made the choice to have the password generator revert to 20 random characters without symbols because we've found that that setting combines strong enough security with the greatest possible website compatibility. We'll always be marked by an official flair, and will always love both 1Password and you. You'll see some friendly people from the 1Password team ready to help you - keep an eye out for /u/1PasswordCS-Blake, /u/agben, u/Zatara214, and more of us!
