In the previous part of this tutorial series, we built a clean foundation for JWT authentication in Laravel — completely from scratch and fully under our control.
Now it’s time to put that foundation into action.

In Part 2, we move from theory and token generation into real authentication flow: logging users in, validating tokens, binding authenticated users to requests, and protecting API routes the clean and modern way. This is where your API stops being just “JWT-capable” and becomes a complete, stateless authentication system.

As always, my goal is to keep things simple while still going deep enough that you understand every step and can adapt the logic to real-world applications. Whether you’re a backend developer in PHP or any other language — or even a frontend/mobile developer curious about how JWT authentication works behind the scenes — this part will give you the clarity you need.

Just like Part 1, I’ve published the full tutorial on Medium to make it accessible for a wider community.
