A new system that securely checks whether your passwords have been made public in known data breaches has been integrated into the widely used password manager, 1Password. This new tool lets customers find out if their passwords have been leaked without ever transmitting full credentials to a server.

Security researcher Troy Hunt this week announced his new version of "Pwned Passwords," a search tool and list of more than 500 million passwords that have been leaked in data breaches. Users can access it online and developers can connect applications to it via an API.

Within a day, the company AgileBits had integrated Hunt's new tool into the 1Password password manager. AgileBits' announcement describes how it works:

Troy's new service allows us to check your passwords while keeping them safe and secure. They're never sent to us or his service.

First, 1Password hashes your password using SHA-1. But sending that full SHA-1 hash to the server would provide too much information and could allow someone to reconstruct your original password. Instead, Troy's new service only requires the first five characters of the 40-character hash.

To complete the process, the server sends back a list of leaked password hashes that start with those same five characters. 1Password then compares this list locally to see if it contains the full hash of your password. If there is a match then we know this password is known and should be changed.

    Not my nephew Fred III, he went into real estate. And always had big problems with his health. The cerebral palsy, very expensive. Very sad, it was going to bankrupt the whole family, big lawsuit. But we settled that one very amicably. That's why I promised the American people, we’re going to have insurance for everybody. There was a philosophy in some circles that if you can’t pay for it, you don’t get it. That’s not going to happen with us.

    My little brother Robert went into cyber, into the cyber games. You've heard of the Id games, right? He bought that one, it's ZeniMax now.

    But my son, my youngest son, Bannon, he's the master of it. So good with computer! And he explains it so well. Much better than our Fake News MSM!
