Hmm, I'm a bit confused here. The question mentions OAuth, but it's not clear to me how that relates to the different options. I'll need to think this through carefully.

Hmm, I'm not totally sure about this one. I know default values are used to display some kind of information, but I'm not confident which specific purpose is correct. I'll have to think this through carefully.
