One popular solution in the Next.js ecosystem is NextAuthJS. Developers frequently encounter challenges when trying to pass user data, especially when using the CredentialsProvider for authentication. This guide will walk you through an effective solution to capture all user variables in your session instead of just the email address. The Challenge You may have encountered an issue where, despite implementing the CredentialsProvider, the authorize function only retrieves the email variable from your API endpoint. This can be frustrating, especially when you need to access additional user data, such as roles or permissions, during the user session. The good news is there’s a straightforward way to tackle this problem! Here’s a typical implementation of the authorize function: [[See Video to Reveal this Text or Code Snippet]] In this setup, while you’re able to fetch user information, NextAuthJS only saves limited information to the session. Let's discuss how to enhance your session data. The Solution To extend the session and include all necessary user variables, you'll need to override the jwt and session callbacks in the NextAuthJS configuration. Below are the steps and code snippets you can use to achieve this: Step 1: Override the jwt Callback The jwt callback allows you to customize the JWT token that is issued when the user logs in.

This provides a more robust authentication experience, allowing your Next.js application to capture all relevant user variables seamlessly.
