I live in Denmark.
In connection with a project I would like to add a "Sign in with Facebook" button to a website. In order to do that I apparently have to register as a Facebook developer on https://developers.facebook.com/.
But during the registration process, they need to confirm my cell phone number by sending me a confirmation code in a text message. I never receive that code. As far as I can tell, Facebook does not support text messages to Denmark. (If you go to https://www.facebook.com/settings?tab=mobile and press "Activate Text Messaging," you will get a list of supported countries. They include countries like Tajikistan and the Democratic Republic of Congo, but not Denmark.)
Facebook support has been less than helpful.
Can anybody suggest what I can possibly do? Do I really need to emigrate just to get a "Sign in with Facebook" button?
