Simultaneous login with instagram and twitter

Hi guys,
I am using meteor accounts-ui to login with twitter and instagram. I want the user to be logged in with both accounts, so that I can make api calls. Is that possible, and if so, how?
I want the users to login with both accounts and then do, well, stuff :smile: Right now, the only way to do this is by first login in to twitter, that logging out and then login in with instagram, so that twitter has an application access_token and instagram has a user access_token. Itā€™s not quite intuitiveā€¦

I did. But that is mainly for -letā€™s say- ā€œre-loginsā€ā€¦ I want the user to be logged in at the same time.
