Is McAfee SafeKey safe?

Low risk

McAfee SafeKey fetches server-controlled JavaScript from its vendor and executes it in every page's DOM.

The extension retrieves account data and per-domain configuration from safekey.mcafee.com on login, including custom_js fields for individual sites. When a page loads, the content script injects that server-sourced code as a script element into the page's document body, running it in the page's origin context across all HTTP and HTTPS frames. Additionally, when enterprise login-logging is enabled by the server response, the extension transmits the visited site URL, site name, and decrypted username to safekey.mcafee.com after each autofill.

Where it sends data
