This article provides a detailed guide to What Is JSON Web Token, how JWT works, and how developers use it in authentication and API authorisation.<\/strong><\/p>\n\n\n\n

When you log in to a website, the application needs a way to recognise your later requests. Otherwise, you would have to enter your password whenever you opened a dashboard, checked an order or updated your profile.<\/p>\n\n\n\n

Different applications solve this problem differently. Some maintain server-side sessions. Others use tokens that clients present when requesting protected resources.<\/p>\n\n\n\n

One widely used token format is JSON Web Token<\/strong>, commonly called JWT<\/strong>.<\/p>\n\n\n\n

You will find JWTs in discussions about SaaS platforms, mobile applications, APIs, microservices and single sign-on. However, popularity has also created confusion. A JWT is not automatically encrypted, does not replace every session system and cannot make an application secure on its own.<\/p>\n\n\n\n

\"What<\/figure>\n\n\n\n

In this Oflox\u00ae guide, we will explain the technology in simple language, examine practical examples and explore the decisions that matter before implementation.<\/p>\n\n\n\n

Let\u2019s explore it together.<\/p>\n\n\n\n
