Provide arguments for Auth0 registration

Incorporating Auth0's provided login and sign-up screen (check it out at https://auth0.com/docs/quickstart/webapp/nextjs/01-login#add-login-to-your-application) into my application has been a seamless process. Upon signup, I have implemented a callback function that creates a profile in my database using the email as the primary key.

However, I've encountered an obstacle on my home screen where there are two buttons: one for "Sign up as admin" and another for "Sign up as a user". My question is, How can I pass information to the Auth0 sign-up screen indicating whether the user clicked "user" or "admin", so that in the callback function I can appropriately create the profile as either "user" or "admin"?

Answer №1

To preserve data between a request and callback, consider including a state parameter in the /authorize request.

If you want to differentiate between "user" and "admin" roles using Auth0, extract the state parameter from the context object (specifically context.request) included in the /authorize request - check out the available context object properties for Auth0 rules here.

The determination of whether to sign up as an admin or user is not done on the front end, but rather in the backend. In terms of auth0 authentication, you can incorporate rules within the auth0 dashboard. Upon signing into auth0, you have the option to choose a rule template or generate your own:

Here is an example of a script:

function (user, context, callback) {
  user.app_metadata = user.app_metadata || {};
  // You can assign roles based on your preference
  // In this scenario, email is used for verification
  //***** ADMINS ARE DECIDED HERE *******
  var addRolesToUser = function(user, cb) {
    if (user.email === "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="c580a8a4aca985a0a8a4aca9eba6aaa8">[email protected]</a>") {
      cb(null, ['admin']);
    } else {
      cb(null, ['guest']);
    }
  };

  addRolesToUser(user, function(err, roles) {
    if (err) {
      callback(err);
    } else {
      user.app_metadata.roles = roles;
      auth0.users.updateAppMetadata(user.user_id, user.app_metadata)
        .then(function(){
          context.idToken[NAMESPACE] = user.app_metadata.roles;
          context.accessToken[NAMESPACE] = user.app_metadata.roles;
          callback(null, user, context);
        })
        .catch(function(err){
          callback(err);
        });
    }
  });
}
