I've implemented sign in with Twitter such that users can log in and I store user's credentials. However, on their tutorial page it says:
Signed in and approved: If the user is signed in on twitter.com and has already approved the calling application, they will be immediately authenticated and returned to the callback URL with a valid OAuth request token. The redirect to twitter.com is not obvious to the user.
In the diagram, my app never redirects transparently, it always asks users to grant access:
Is there something I have to do to make my app redirect transparently? My website is over https if that has anything to do with it.
