Good idea to automatically give your email, name, photo and other details to _every_ site your visit, really? Of course the login should be a voluntary action by the user.

Btw luckily what reported doesn't work for me, the site ask to login. It should not be even possibile, at least without exploting a bug/vulnerability.

Hmm, maybe it's an A/B test.

This is actually very much possible. I just learned that it's implemented using Google One Tap for Web. [1] That's the web version of One Tap, which lets Android app developers add single-click login using a Google account.

Apparently one of the features of the SDK is automatic sign-in [2], without any user interaction, which Quora seems to be using. In contrast, LinkedIn and Medium also use the same SDK but only suggest logging in with Google in a pop-up. [3]

Edit:

There's a way to turn it off. Disable "Google Account sign-in prompts" setting in Google account permissions [4].

This sounds like a dream come true for any government, online marketer, or malicious hacker.
