To check if your password or email has been exposed. Google has launched Password Checkup, an extension that proactively and silently notifies us when we log in with a username or password that has been exposed.
check if you are a victim by sending your (encrypted) password to Google
Google promotes Password Checkup as a tool to help you know which accounts to protect after a given breach, and you’ll get a visual warning when you sign in if Google knows your username and password are in a known security breach.
To do this, they need to receive your password, although they ensure that they will never record information about accounts, passwords or devices. In that sense, Google’s promise is that Password Checkup sends all your data anonymously, encrypted and hashed, so that, as they say, they can’t see your data.
The extension accesses a database, but the warnings Checkup gives you happen locally. That is, Google does not have to know that your specific passwords have been exposed. There are, as we have said, other services that are worth knowing these same details, but the way in which this extension works is very close to a large number of users who will not be aware of the alternatives.
Therefore, it would be ideal for Chrome to arrive with this extension pre-installed or as part of the browser, as is the case with the password generator. Still, no matter how much use is made of these Google solutions, always remember to use strong passwords and a trusted password manager.
