Ruby SDK for Userbin

Userbin provides an additional security layer to your application by adding user activity monitoring, real-time threat protection and two-factor authentication in a white-label package. Your users do not need to be signed up or registered for Userbin before using the service and there's no need for them to download any proprietary apps. Also, Userbin requires no modification of your current database schema as it uses your local user IDs.

Getting started

Add the userbin gem to your Gemfile

gem "userbin"

Install the gem

bundle install

Load and configure the library with your Userbin API secret.

require 'userbin'
Userbin.api_secret = "YOUR_API_SECRET"

Monitor a user

First you'll need to initialize a Userbin client for every incoming HTTP request and add it to the environment so that it's accessible during the request lifetime.

To monitor a logged in user, simply call authorize! on the Userbin object. You need to pass the user id, and optionally a hash of user properties, preferrable including at least email. This call only result in an HTTP request once every 5 minutes.

Full example

class MyController < ApplicationController
  # Define a before filter
  before_filter :initialize_userbin

  # Your controller code here

  private
  def initialize_userbin
    # initialize Userbin and add it to the request environment
    env['userbin'] = Userbin::Client.new(request)

    if user_signed_in?
      user_properties = {
        email: current_user.email,
        name: current_user.name # optional
      }

      begin
        env['userbin'].authorize!(current_user.id, user_properties)
      rescue Userbin::Error
        # logged out from Userbin; clear your current_user and logout
      end
    end
  end
end

As a last step, you'll need to clear the Usebin session when the user logs out from your application.

  env['userbin'].logout

Done! Now log in to your application and watch the user appear in your Userbin dashboard.

Add a link to the user's security settings

Create a new route where you redirect the user to its security settings page, where they can configure two-factor authentication, revoke suspicious sessions and set up notifications.

redirect_to env['userbin'].security_settings_url

Two-factor authentication

If the user has enabled two-factor authentication, two_factor_authenticate! will return the second factor that is used to authenticate. If SMS is used, this call will also send out an SMS to the user's registered phone number.

factor = env['userbin'].two_factor_authenticate!

case factor
when :authenticator then render 'authenticator_form'
when :sms then render 'sms_form'
end

The user enters the authentication code in the form and posts it to your handler.
