TryHackMe JWT Security - Full Walkthrough | TryHackMe Walkthrough on Token-Based Authentication

Master JWTs & Token Security | TryHackMe Room Guide

🏷️🏷️ Room Link: https://tryhackme.com/r/room/jwtsecurity

In this room, you will learn about JSON Web Tokens (JWTs) and the security associated with them. With the rise of APIs, token-based authentication has become a lot more popular, and of these, JWTs remain one of the most popular implementations. However, with JWTs, ensuring the implementation is done securely is incredibly important. Insecure implementations can lead to serious vulnerabilities, with threat actors having the ability to forge tokens and hijack user sessions!
