It’s hard to explain in words what I’m talking about.

When you open an app on your phone, sometimes it requires you to give a username/email and password credentials. Some applications have an option to “Login with Facebook” and quickly allows the user to login to facebook. By doing this, it gives you a new account by using your facebook information (I guess?).

I know you can do this with my websites too.

My question is what is this called? does facebook devs have a specific name for this? If so, how can I implement it through android, and even through web development?

Thanks!!

UPDATE: For example: When you log into this stackoverflow site. You are able to click on the “login with Facebook” and quickly login without have to fill in information. I know it’s the same way with the stackoverflow android app.
