Two Factor Authentication with Nexmo Verify

A Rails (Ruby) app showing how to implement two-factor authentication using the Nexmo Verify API.

Prerequisites

• A Nexmo account
• Ruby 2.1+ and Bundler installed
• Rails 5+ installed

Getting started

# clone this repository
git clone git@github.com:Nexmo/ruby-2fa.git

Next you will need to sign up for a Nexmo account and get your API credentials from the API dashboard and put them in your .env file.

Finally all that's left is to start the server.

rails server
