This is also related to #460. Generally, there are a lot of comments in the Rocket.chat community and issues in the main Rocket.chat website about iframe authentication or logins, so there's a lot of interest in the issue and discussion, but I cannot find a proper documentation or some code that helps in this. I personally need to know how to do this in Meteor... thanks for opening the issue, it's very important for me!
