How to Block Third-Party Sign-In Prompts in Google Chrome

The Intrusive Identity Prompt

Google operates a massive “Sign in with Google” API that is embedded across millions of independent websites (like Reddit, Pinterest, or local news blogs). If you are signed into your Google account in Chrome, the moment you visit one of these third-party websites, a massive “Sign in” pop-up slides down from the top right corner of the screen, aggressively demanding that you link your Google identity to the site. This prompt completely obscures the content you are trying to read and requires manual dismissal on nearly every single website you visit. You must completely paralyze this identity federation protocol.

How to Block Third-Party Sign-In Prompts

You can permanently sever the browser’s ability to inject these login banners via the Site Settings.

  1. Open the Google Chrome desktop browser.
  2. Click the three vertical dots (â‹®) in the top right corner and select Settings.
  3. In the left-hand sidebar, click on Privacy and security.
  4. In the main window, click on Site settings.
  5. Scroll down to the “Content” heading and click to expand Additional content settings.
  6. Click on Third-party sign-in.
  7. Under the “Default behavior” heading, select the radio button for “Block sign-in prompts from identity services.”

A Frictionless Web

The change takes effect instantly. Google Chrome will completely sever its internal connection to the identity federation API. The browser will instantly auto-reject the background scripts that trigger the slide-down Google login banner on third-party websites. You can now browse the internet smoothly and read articles without constantly fighting off aggressive demands to link your personal Google account to random forums and blogs.
