You are probably wondering what this is and why you need it. Read this post to find out.
What is a JWT?
JSON Web Token, more commonly known as JWT, is a lightweight JSON-based security token. It is typically used to securely transmit information between two parties.
Its main objective is to provide three main features: authentication, authorization, and data integrity.
As Web Technology advances, new technologies are created. Instead of a cookie that only has the information that the programmer has wanted to include, the JWT token can have any type of data included in its code.
What are the main advantages of a JWT token?
The main benefit of using the JWT token is that it reduces the transmission of information to its minimum.
This is due to the fact that when transmitting data between applications, the most important thing is to know who wants to access your information and not what he wants to do with it.
Therefore, a JWT token has two parts: an authority part and a payload part. The first one indicates which institution or person has given us permission to access the data; and the second part is where we can see if we really have that permission or not.
This token will be valid for a certain period of time, but if someone is able to intercept it, they will be able to access all the information included because they know the decryption key!
This is why it’s important to use keys that are enough complicated so that only you will be able to decode your tokens and get access to your data.
But don’t worry, there are many platforms that can help you save time and optimize your project at the same time. Here I leave you a Javascript API capable of generating thousands of tokens in just one click! Create your own JWT Tokens in Minutes!
