Standard protection against websites, downloads, and extensions that are known to be dangerous.

Detects and warns you about dangerous events when they happen

Checks URLs with a list of unsafe sites stored in Chrome. If a site tries to steal your password, or when you download a harmful file, Chrome may also send URLs, including bits of page content, to Safe Browsing.

Help improve security on the web for everyone

Sends URLs of some pages you visit, limited system information, and some page content to Google, to help discover new threats and protect everyone on the web.

Warn you if passwords are exposed in a data breach

Chrome periodically checks your passwords against lists that have been published online. When doing this, your passwords and usernames are encrypted, so they can’t be read by anyone, including Google.
