DuckDuckGo was originally just a search engine, the main feature is to protect user privacy, promise not to track or record user searches, and behavior when searching. After that, DuckDuckGo expanded its product lineup, successively launching extensions for browsers such as Chrome and Firefox, as well as its own browser (currently available in iOS, Android and Mac versions), all of which emphasize the protection of user privacy by these products.

Recently, DuckDuckGo AnnounceGoogle sign-in prompts on websites will be actively blocked in Chrome, Firefox, Brave, and Microsoft Edge apps and browser extensions, citinguser use One-click Google accountLogged-in websites and apps may be tracked by Google.

Despite Google’s explicit statement that “data from Sign In With Google will not be used for advertising or other non-security purposes,” DuckDuckGo says their tests prove that Google is still collecting data.

The test revealed that Google is collecting data on websites when signing in with Google. For example, on investing.com many requests are sent to https://securepubads.g.doubleclick.net/gampad/ads? ,Include the full page url in the request parameters.

In testing, the DSID cookie sent with these requests had a value of NO_DATA if we were not logging into the site through Google. If we log into the site via Google, the DSID cookie sent with these requests has a long hexadecimal value.

DuckDuckGo considers these to be privacy risks and takes a rather aggressive approach: blocking all Google login prompts and pop-ups, giving users no choice.
