Differences between OAuth 2.0 and JWT (JSON Web Token)
Hello guys, both OAuth 2.0 and JWT (JSON Web Tokens) are two widely used authentication and authorization protocols in modern web applications. While both serve similar purposes, there are some key differences between the two that are important to understand, which we will see in this article. This is also an important interview question and if you are preparing for Java and Microservices developer interviews, it's better to know how this two technology works and what are the key differences between then. In short, OAuth 2.0 is primarily used for authorization, whereas JWT is primarily used for authentication. OAuth 2.0 uses access tokens, whereas JWT is a self-contained token. OAuth 2.0 has a complex authorization flow, whereas JWT has a simple flow. OAuth 2.0 provides better security as it reduces the risk of unauthorized access to protected resources, while JWT can be intercepted if not properly secured. OAuth 2.0 access tokens are short-lived and need to be refreshed periodically, whereas JWTs do not expire.
