How to implement 'Token Based Authentication' securely in PHPFox?

Here is a general outline of how to implement token-based authentication in PHPFox:

1. Create a login endpoint for users to submit their credentials.
2. Verify the credentials and, if valid, generate a JSON Web Token (JWT) that contains the user's information and a secret key.
3. Send the JWT to the client, who should store it in a secure way (e.g. in an HTTP-only, secure cookie).
4. On subsequent requests, the client should include the JWT in the Authorization header of the request.
5. The server should validate the JWT by checking its signature and expiration time. If the JWT is valid, allow the user to access the requested resource.

It's important to use a secure method for storing the JWT on the client side, such as an HTTP-only, secure cookie. Also, you should use a secure method for storing the secret key used to sign the JWT on the server side. Additionally, it is recommended to validate the token on every request, and also check the token expiration time, and invalidate the token after a certain amount of time.

You can use a library such as firebase/php-jwt to handle the JWT generation and validation in PHP, and use the built-in session management features of PHPFox to store and retrieve the JWT.
