Spring Security OAuth2 VS JWT(JSON Web Tokens)

In this article, we will learn the difference between Spring Security OAuth2 and JWT.

Spring Security OAuth2

Spring Security OAuth2 is a nice authentication and authorization (i.e. security) framework that gets the power of OAuth 2.0 to the Java Spring ecosystem. This Spring Security OAuth2 allows third-party applications to get limited access to HTTP service.

OAuth, also called Open Authorization, is a kind of protocol mainly used in the industry for authorization purposes. This OAuth lets third-party services access our information without having to share our password. This is achievable by the use of tokens called authorization tokens, which set a secure connection between users and providers. and this OAuth2 is taken one step ahead of OAuth and it brings more security.

This Spring Security OAuth2 gives us a wide range of features that facilitate the process of executing OAuth2 authorization in Spring applications e.g. Flexible Authorization Protocols, Seamless integration with other components of Spring, Secure Resource Server, etc.

JWT (JSON Web Tokens)

JSON Web Token i.e. JWT, is a most used standard that gives us a straightforward and self-contained method for securely exchanging data between different parties utilizing as JSON format. This is complete trust and verify this information because this is digitally signed. JSON Object is a suitable means for securely transferring data online. JWT claims are stored as a JSON object and secured with a digital signature because it makes use of JSON Web Signature (JWS).

JWT has many key features Compactness as JWT is less verbose, JWT is generally Statelessness they do not need server-side session storage, Flexibility and Security, etc.

Difference between Spring Security OAuth2 and JWT

Similarities between Spring Security OAuth2 and JWT

• Both Spring Security OAuth2 and JWT are used to improve the security of web applications and that is similar in Security Enhancement.
• Both Spring Security OAuth2 and JWT depend on token-based authentication and authorization mechanisms.
• Both make use of JSON, JWT uses JSON to represent the claims between two parties. OAuth2 tokens JSON format for token responses.
• Spring Security OAuth2 and JWT both Support RESTful Services.
• Spring Security OAuth2 and JWT both have huge numbers of Audience, Community and Ecosystem Support and with comprehensive documentation, libraries, and frameworks available over internet.
