Add multi-factor authentication to a ruby on rails websites

Job ID: 33096845

Budget: $15 – $25 USD

We have a small web application with about 50 paying users and want to add multi-factor authentication. The app is built on ruby on rails and currently runs on Heroku with integration from Github.

We currently have 2-factor authentication via the email that users sign up with but would like to add text and app-based options for users. Ideally, we would want a free option given our small size. Google Cloud Identity Platform could work.
