> I've got to say, I really wish there were a way to know whether I already used Facebook, Google, or Apple to log into a site or app before.

Bookwalker (from Japan) draws a big red box around the login you used last on a given device. Presumably they store a cookie/sharedpreferences with it. It doesn't look pretty, but it helps.

That's useful, but on any device of mine I'm usually logged in anyways. What would be really useful is knowing this when I log into a new computer.
