A lot of websites these days (including this one) offer Facebook, Twitter, and/or Google login. Usually there's also an option to use old-style username/password credentials. I'm never sure which option to select. I use my real name on Facebook and Twitter. On some sites, I'd rather be anonymous.
Not so much Stack Exchange, but the privileges requested by some other sites seem outrageous. For example, I recently went to sign up for weheartit.com and here's the Twitter "OK" page...
Are they seriously saying they're going to follow people and post tweets using my account without my intervention?
Who would agree to that?
Or do they mean "we'll do those things on a case-by-case basis if you allow it?"
I feel as though there's something I'm not understanding here.
My dilemma is that 3rd party login seems convenient and I could see the advantages of having one consolidated identity across the social landscape, but the privileges they ask for always seem so over the top.
If anyone could explain to me some context or details of how this sort of thing works I'd really appreciate it.
