Google has a tool designed to securely analyze your passwords against a database that is known to be hacked and compromised. The password checker is available as an extension or a web service. Here’s how to use it.
Check your passwords with extension
If you don’t use a third-party password manager or don’t use strong and strong passwords, Google’s password checker extension will help you find out if the password you use for non-Google sites has been exposed.

Whenever you log into your account, the extension checks the password against a database of known violations — hashes and compares the results. If the password you are using is on the list of known violations, it will alert you and prompt you to reset your password.
Launch Chrome and go to the Chrome Web Store for the Password Check Extension. Once there, click «Add to Chrome» to start the download.
Read the permissions for the extension and then click «Add Extension» to add it to your browser.
Once the extension is installed, the icon will appear in the toolbar or Chrome menu. By clicking on it, you will see how many passwords have been analyzed in the last week.
Alternatively, you can enable a Chrome flag that does the same. The difference is that the whole process happens in the background, only alerting you if it detects a cracked password.
You can enable the flag by copying the following address and pasting it into the Chrome Omnibox:
хром: // флаги пароль обнаружение утечки / #
Select «Enabled» from the dropdown list and then click «Restart» to restart the browser.
