Is it possible to test out Oauth Login Authentication (Facebook, Twitter, Google) without a domain and hosting?

Question

Is there a way without actual domain name and a hosting ?

Can we use localhost in some way ?

I am using Python and Django !

Answer 1

This is what I have found out :

It can be done, simply by using 127.0.0.1 in the callback/redirect uri

It worked and I am able to test my app on localhost.
