Twitter Authentication 401 Unauthorized - MVC4/5

ASP.NETErrorsWeb Development

Hey everyone,

Just testing out twitter authentication and ran into the following error:

Response Status code does not indicate success: 401 (Unauthorized).
…

To fix this, all you’ve got to do is go to you Twitter App settings and:
– Add a callback url (doesn’t have to be real)
– Check the ExternalLoginConfirmationViewModel checkbox
