FIDO2-Demo-App | demo Ruby on Rails application featuring FIDO2 password | Application Framework library

To fully set up this web application you will need a domain name and an SSL certificate. Prepare your Ubuntu system by installing Ruby, NodeJs, Yarn, Rails and dependencies. Enter the folder where you want to place the app's folder (e.g. cd ~/Downloads/) and clone this GitHub repo. Initialize the dependencies of the app, re-build database and insert test user (username: test, password: test). Configure application for localhost usage. WebAuthn works on localhost, you will need to have a FIDO2 or FIDO U2F authenticator on the host machine. To deploy the application and test it to your phone, you will need to set it up on a server with a domain and an SSL certificate, due to the fact that WebAuthn only works under HTTPS and an domain. Also, you can create a self singed certificate but still, the application will have to be served from a domain. At the commands below, change the your.domain.com to your domain name. You can delete the test user by running echo 'User.delete_by(email: "test@test.com")' | bundle exec rails c. You can use an Apache web server as a proxy to serve the web application and handle both the domain and the SSL certificate. Here is an example configuration of Apache with a Let's Encrypt certificate that proxies the requests to the server that runs the FIDO application. (change the example.domain.com to your domain and the 192.168.99.99 to the application server's IP).
