How it works
Festival registration portal uses nexmo for for double verification via email and nexmo-verify api.
Signup page - input festival details On submit - email sent On email verification page - ask for phone verify (via sms / phone call) On Nexmo verification done - Registration - done.
Same flow for , Change password for the festival.
Challenges I ran into
Nexmo Limitation with voip phones which needs a paid a/c to test, And we don't have many phone accounts to test.
