I am trying to authorize my clients Twitter widget which requires me to login to their account. I have signed into their twitter account successfully but when I try to login to Twitter developers with the same username and password I get this error: “Sorry, we couldn’t log you in with this Twitter account. Double check your credentials, and be sure your email address is confirmed!”.
I have even tried to use his email in replace of the username.
Is there anything I can do to login successfully?
