Javascript Rule-Based Authentication

Add attributes to a user for specific connection

How it works?

This rule will add an attribute to the user only for the login transaction (i.e. they won't be persisted to the user). This is useful for cases where you want to enrich the user information for a specific application.

How do I use it?

Just create a new rule in the Auth0 dashboard, and copy the following code replacing the placeholders with the appropriate values.

What is Rule-Based Authentication?

A rule is arbitrary JavaScript code that can be used to extend Auth0s default behavior when authenticating a user. Enabled rules will be executed in the order shown below for all users and applications as the final step of the authentication process.

Rules can be used to enrich and transform the user profile, deny access to specific users under certain conditions, retrieve information from external services and much more. For more information about rules, please check the documentation
