Is it possible to get accessible information from Facebook and insert it into labels?

Question

Facebook

To begin with, he is interested in general, is it realizable? For example, I have a Questionnaire (let there be registration). Add a Facebook button there, which does not authorize you from your FB profile, but gets (if exist) all the data - transferring them to the registration fields.
If this is possible to implement, I will be very grateful for any useful information) I just never dealt with such things. Guides, tips, whatever :)
ps The whole project is based on asp.net and c#

Answer 1

There, when authorizing through OAuth, you can get enough information, unless of course the user allows access.

Answer 2

In any case, user authorization on Facebook is needed, but you need to know which account to pull data from.
