I'm working on a project that involves social integration with Facebook, Twitter, YouTube, and Instagram. I authenticated them all with webAuthenticationBroker and implement the un-authenticate functions.
For Facebook, Twitter, and YouTube, they are easy work just remove stored access tokens and all authentication data. And when I launch the webAuthenticationBroker again, it asks me to fill username and password again, as it should be.
But for Instagram, I did the same with un-authentication and then try to re-authenticate using webAuthenticationBroker again with different username. This time the broker did not ask me anything, only it show a pop-up and a spinning progress ring. One time to
get auth code, another time to get access token. Then it log me in with same old user that just logged out.
Is there anything like cache or cookies or something beyond my knowledge that I can clear them just to make it forget my authentication data and allow me to authenticate with another user?
Thank you.
