Disable Login with Google

Question

Even if you disable Chrome's automatic sign-in in the browser's settings:

Google seems to follow you when a website offers Login with Google:

Is there a way to disable Login with Google at all for external websites?

Answer 1

This feature is called one-tap. Its documentation seems to be gone from the website, but StackOverflow has some points. The script in charge is https://smartlock.google.com/client. If you have an adblock extension or something like Greasemonkey, you can block it.

If you want to get rid of the button too, you can block https://apis.google.com/js/platform.js.

Answer 2

Not really sure if this is what you're referring, but I have had similar issues with inconsistencies when signing to sites with Google account, so I disabled the cookie jar/browser consistency.

I reckon perhaps this has to do with a flag in Chrome's settings - #account-consistency

Do the following to resolve:

• Load chrome://flags/#account-consistency in the browser's address bar. Google Chrome should display the flag Identity consistency between browser and cookie jar at the top.

• Set the flag to disabled with a click on the menu and selecting disabled from the context menu.

• Restart the Chrome browser.
