Hey, welcome back. In the next few lessons we'll deal with JSON Web Tokens and authentication bypass for them. If you don't know what JSON Web Tokens are JWTs are, there's a hidden video towards the end of this module. We'll bypass authentication through a password reset and will provide a solution for demonstrating and exploiting JSON Web Tokens and another solution for patching vulnerabilities involved in the Parse Method. I hope you're learning from seeing and hearing the third process. After these screen-casts, you should be able to properly implement authentication methods like JWTs, and practice finding vulnerabilities in a large code base. Remember, these lab is build together and make up your final project. Let's get started.
