If I sign in with Google, won't Google know I have an account on that site? I would consider that a privacy issue.


If you put email account in the login they will know on the first e-mail the site sends to your email


Not if I don't use a Google email address. :)


Yes but then you wouldn't have been able to use Sign in with Google anyway.


Why is Google just knowing you have an account on that site a privacy issue?


I think it's to do with these new 'Signals' they seem to be building profiles of interest based on services.

Oh Google doesn't need to go so far to know you have an account on that site.

A single tracking cookie shared with their one of their many many partners is enough


The can just scan for signup emails and get the same thing


And Here's Why That's a Good Thing
