Introduction to OAuth 2.0
Explore the core concepts and workflow of OAuth 2.0, including roles, security benefits, and integration steps. Understand how to implement OAuth 2.0 in web applications for secure and scalable user authentication using providers like Facebook.
OAuth 2.0 is an open standard authorization protocol that enables secure and delegated access to resources between different services. This lesson will provide an in-depth understanding of OAuth 2.0 and provide a guide to the process of integrating it into a web application. Additionally, we’ll explore the advantages of using OAuth 2.0 for authentication and authorization.
OAuth 2.0 protocol
OAuth 2.0 is an authorization framework that lets applications get limited access to user accounts on services like Facebook, GitHub, or Google. It authorizes external applications to access specific account information without exposing the user’s credentials.
It’s designed to authorize access to resources without exposing user credentials. It operates on a set of defined roles:
- The resource owner (user)
- The client (application)
- The authorization server
- The resource server
Advantages of OAuth 2.0
Here are a few advantages of using Oauth 2.0:
-
Enhanced security: OAuth 2.0 eliminates the need for applications to store user credentials, reducing the risk of unauthorized access. ...
