How do know if a user is logged in at server, and iron-router level?

I’m building a prototype in Meteor for a social app. I’m built a rest endpoint with the package restivus for Swift in Mobile with UIWebView to manage login (through the hashedToken in loginTokens. I’ve created a social login that works fine, and it works across the web and mobile, What interesting is the login state of the user is not shared between both the web and mobile (UIView) app that I’ve made. Is there a manual way to log the user with a server method? Is there a simple is Logged in property?
