Following the Instagram documentation I'm able to authenticate a user and retrieve an access_token easily
But now I want to change of Instagram account which is impossible since the browser automatically call my callback URL because I'm already signed in with an account (there is no login / authorization form again)
To explain what happen here is the authenticate / authorization flow :
- Open a browser asking user to log and authorize
- User fill up form and submit (this step is skipped when user is already signed in !)
- Browser redirect to callback URL
You see step 2 is skipped so we can't login with another user
Does the Instagram have a parameter to force relogin ?
