This initial setup worked well for local development and prototyping. However, as I considered sharing the app with friends or making it publicly accessible, I wanted to experiment with securing user data. Authentication quickly became the next logical step — ensuring that only authorized users can access, modify, or view their own financial records Thanks for reading Logs of a Data Engineer!

In this post, I’ll walk you through how I added secure, JWT-based API authentication to the finance tracker — turning a working prototype into a more secure and production-ready application. Note: I’m not a security expert, and this project is primarily for learning purposes — so some areas may still need improvement or corrections :) This is a Next.js project bootstrapped with create-next-app. This project utilizes Plaid and OpenAI technologies as well as shadcn to unlock insights into your spending and transactions. Simply clone and deploy with your own Plaid Developer API Key to host a private Mint App clone, boosted with Vercel AI SDK & Generative UI. Take it forward, contribute or commercialize - go nuts.
