Restrict JWT Token with IP Address using Laravel
Authentication is one of the most important parts of any web application. Handling authentication between mobile application and server side can be tricky and demand more secure approach. One of the best approach is using JSON Web Token (JWT).
The structure of a JWT token consists of header, payload, and signature. Basically, server side just create the token with existing claims and the Front-end like VueJS use as authorization of any API request. Server side just validate whether valid token from issuer or not. Enough talk, here the question :-
Are JWT tokens secure?
By default JWT are not encrypted and the token is simply a base64 encoded that can be easily decoded to see the plain JSON content that the token carries.
So the response to the question is ‘It depends’. JWT depends heavily on a good configuration when issuing the tokens and in a correct use and proper validation of the consumed tokens.
For best practice, you may refer here. The best practice covers on how you can secure JWT. But, none of it mention on how to restrict the JWT token based on IP Address, or etc…
