Link several Twitter accounts to a Meteor app


I am building a Meteor app where the user can link several Twitter accounts to post on their behalf.

I manage to make it work fine with one account (user the twitter package). Now, the problem is that whenever I want to authenticate the app with Twitter again, the Twitter popup doesn’t allow me to enter a new username/password which would be needed to link a new account.

So my question is: how do I ‘force’ Twitter to let me enter new credentials in the popup? Thanks!
