For go links. go.rocket.chat we need to be able to pass ?userId=id&token=blablah and have it login.

It doesn't have to be this exact query param, but something to allow us to pass them to login. Could even do hash based so it won't be sent in load balancer logs. Something like /#/?userId=id&token=blablah would keep it out of the logs

On iOS/Android this already works. On web we need to detect these and do: meteor.loginWithToken
