How Does Chrome Know About Compromised Passwords?

Chrome is able to detect compromised passwords through its built-in security feature called "Password Checkup". This feature monitors your saved passwords and compares them against a constantly updated list of compromised credentials known to hackers. If any of your passwords match those on the list, Chrome will alert you to take action and change that specific password to secure your account.

Another way Chrome knows about compromised passwords is through data breaches. When a website or service you use is involved in a data breach, hackers may obtain user credentials, including passwords. Chrome can access databases of leaked credentials and cross-reference them with user accounts to determine if any passwords have been compromised.

By leveraging these methods, Chrome helps users stay informed about potential security risks and prompts them to take proactive measures to protect their online accounts.
