Avoiding email while registering a user in Authy

Question

I am creating a sign up route where I will ask for phone number first and then, after verification, I will get the other information. I am using twilio Authy for that purpose. From the documents, i have noticed that email address is a required field while registering a user. Is there any way by which I can register a user without email address or can i use a default email address for every user?

You can add an Authy user without taking personally identifiable information following the process in the documentation here. Note that the user will have to be using the Authy app.

To do so, you need to create a JWT containing the following information:

{
  "iss": "{authy_app_name}",
  "iat": {issue date in NumericDate},
  "exp": {expiration date in NumericDate},
  "context": {
    "custom_user_id": "{custom_user_id}",
    "authy_app_id": "{app_authy_id}"
  }
}

Then add the JWT to a URL that you turn into a QR code. The URL format should be:

authy://account?token={JWT}

You can then poll or set up to receive a webhook to get notified of the user's authy_id once they have scanned the QR code. You can read more on this in the documentation.

Let me know if that helps at all.
