Mapping Auth0 User Profiles to WordPress User Roles During Sign Up

Apr 30, 2026

Overview

Mapping user roles from an Auth0 profile to a WordPress user during initial sign-up ensures that users receive the correct permissions immediately. To achieve this, administrators can utilize the auth0_create_user_data filter in WordPress to intercept Auth0 data and assign specific roles based on the user's Auth0 profile information.

Applies To

Auth0
WordPress Integration
User Roles
User Profiles

Solution

When a new user signs up in WordPress through an Auth0 login, administrators can modify the user data with the auth0_create_user_data filter. This filter runs once during initial user creation, useful for setting a user role. It allows the functions.php file to intercept the data that Auth0 sends and apply custom logic.

To assign a specific WordPress role based on the user's Auth0 profile information during initial user creation, add a similar PHP snippet to the theme's functions.php file.

function sync_auth0_role_to_wordpress( $user_data, $userinfo ) {
    // Look for the role in the user's app_metadata from Auth0.
    // The namespace (e.g., "https://example.com/roles") should be unique.
    if ( isset( $userinfo->{'https://example.com/roles'}[0] ) ) {
        $user_data['role'] = $userinfo->{'https://example.com/roles'}[0];
    }
    return $user_data;
}
add_filter( 'auth0_create_user_data', 'sync_auth0_role_to_wordpress', 10, 2 );

How do administrators update user roles on subsequent logins?

The auth0_create_user_data filter runs only once when the user account is first created in WordPress. To update a user role on every login and keep it synchronized with changes in Auth0, utilize the auth0_user_login action instead. This action runs every time a user logs in, allowing the integration to check the Auth0 profile and update the WordPress role accordingly.
