Why JWT isn't enough to secure your app
When I first started building authentication systems, I thought:
"If I'm using JWT, my app is secure."
I was wrong.
JWT solves authentication—it tells your server who the user is.
It doesn't automatically solve:
Authorization (What is the user allowed to do?)  Token theft Token revocation after logout XSS or CSRF attacks Rate limiting Input validation Secure storage of tokens
A secure application is built with layers, not a single technology.
Here's what I consider a solid authentication stack:
Short-lived access tokens
Refresh token rotation
HttpOnly & Secure cookies
Role-Based Access Control (RBAC)
Input validation and sanitization
Rate limiting
Security headers
Continuous logging and monitoring
One lesson I've learned:
Security isn't something you add after your app works. It's something you design into every feature from the beginning.
JWT is one piece of the puzzle—not the whole picture.
What's one security practice you think every full-stack developer should implement by default?
