According to Google, technology developed in partnership with researchers at Stanford University allows the system to track possible leaked passwords without storing the data. Your personal access codes would therefore always remain private. Here's how to use the feature to protect passwords from any website on your computer.
Step 2. Make sure you're signed in to your Google Account. To do this, click on your photo in the browser bar and make sure sync is on.
Step 3. Then keep an eye on the extension icon in the browser. If a recently used password is in a public database of leaked data, the plugin will issue an alert and recommend the immediate change of the code on the corresponding site.
