   -> ... in a new terminal window:

   composer card export -c admin@trustfabric-perfect -f admin-plus-cert.card

   -> in browser window go to the following address to authenticate: http://localhost:3000/auth/github (Sign in to your GitHub account. Since the application has not been started yet, a message will appear informing you that a connection to the server at localhost:4200 was not possible.)
