Google Chrome protects your passwords using multiple layers of security designed to keep your login information safe.
First, Chrome stores saved passwords securely using encryption. Your passwords are encrypted on your device, which helps prevent unauthorized access.
If you are signed in to Chrome and have sync enabled, your passwords are stored in your Google Account and protected by Google Account security. This includes encryption during transfer and storage on Google’s servers.
Chrome also offers a Password Manager. It can generate strong passwords, save them, and autofill them when you log in to websites. This reduces the need to reuse weak or duplicate passwords.
Another important feature is Password Checkup. Chrome can alert you if your saved passwords are compromised in a known data breach, weak, or reused across multiple sites. This helps you take action quickly.
For added protection, Chrome may require authentication before revealing or autofilling passwords. This can include your device password, fingerprint, or face recognition.
Chrome can warn you if the username and password that you use to sign in to a website were involved in a data breach. This setting is turned on by default.
You can also use Chrome to check all of your saved credentials at the same time. Chrome checks your saved passwords and then lets you know if any of them were exposed in a data breach.
To check your credentials, Chrome first encrypts your username and password. Then it sends the encrypted credentials to Google for comparison against an encrypted list of known breached data. If Chrome detects a match between the encrypted sets of data, it displays a warning that prompts you to change your password. Google never learns your usernames or passwords during this process.
You can check if a data breach exposed any of your saved usernames or passwords. You can also choose to get automatic warnings about credentials when you sign in to a site where a data breach was detected.

You can also set a custom sync passphrase. This adds an extra layer of encryption so that only you can access your synced passwords.
Additionally, Chrome integrates with Safe Browsing to warn you about phishing sites that may try to steal your login details.
In summary, Chrome protects your passwords through encryption, account security, breach detection, and authentication measures, helping keep your online accounts secure.
