I'm diving into web development and building projects for my portfolio, but I've hit a major hurdle: authentication. I'm currently using the PERN stack, and I want to enable user sign-in so that their data is stored in a database. It seems like everyone knows how to implement this, but I'm struggling to grasp it. What's the best way to learn about authentication? It feels complex and a bit intimidating, so I'd really appreciate any advice you can share!

Start simple! Begin by creating an authentication form where you check a plain password against a stored one in your database. Once you grasp that, look into securely hashing passwords (Argon2 is a great option) and how to match hashed passwords. After that, learn how to maintain the authenticated state using cookies. That’ll cover the basics for you!
Honestly, this was super helpful! I was finding tons of complicated stuff everywhere. Thanks for breaking it down!
