In other words, if Facebook or Reddit suffers a widespread data breach (and your credentials are included), the Password Checkup tool will automatically help you take action. After the warning users can change their password in order to prevent their account from hacking.
Google is making it very clear that using Password Checkup does not share any identifying information about users, their accounts, passwords, or devices.
It can be noted that Google does not get any access to the user details, but will only offer information that a security breach has happened and also inform if your account details are compromised or not. "This is where the new Password CheckupChrome extension can help". With this new Chrome extension the company aims to keep the Google Accounts safe by proactively detecting and responding to security threats.
Ever since digital big leaguers like Facebook - and even its own Google+ - were hobbled by data privacy gaffes that exposed the personal data of its users, Google has been on a mission to make sure it covers his rear end the best it can. Once installed, it will check every time you sign in to an account using a username and password. Password Checkup addresses all of these requirements by using multiple rounds of hashing, k-anonymity, private information retrieval, and a technique called blinding.
"We want to help you stay safe not just on Google, but elsewhere on the web as well", Google said today. If users have the Cross Account Protection implemented, they will be notified if a Google account has been compromised. While the Google account itself has had added protections to deal with attackers and malicious parties, it is the first time the company is improving the security of Google sign-in for third-party platforms. This is why the company has created its new Cross Account Protection feature.
