OAuth, OpenID and JWT - What exactly are these terms and their differences
OAuth, OpenID and JWT - What exactly are these terms and their differencesIn this week's newsletter, let me explain to you the terms OAuth, OpenID and JWT and what are they used for.
Authentication and Authorization are two terms used interchangeably in the context of Identity management, but serve two different purposes. Authentication means validating the existence of a user against a system. It is the process of confirming the identity of a user or entity. Authorization comes after Authentication. It means verifying whether the user is permitted to use a resource in a system by means of any secret information and granted access. OAuth is a protocol which explains how a user should be authorized by a system. It was principally developed for Authorization but is generic to implement for larger purposes like API management and others. OpenID is used for authenticating a user against a backend. JWT is a compact, self-contained method for securely transmitting information between parties as a JSON object. In this week’s newsletter, let me explain to you in detail about all of these terms, and potential differences between them. You can check the article here - https://referbruv.com/blog/authentication-vs-authorization-oauth-openid-and-jwt-explained/ I hope this article will be of use to you. I’ll see you next week with a new topic. Have a great week ahead!
