OAuth 2.0 is a standardized protocol for granting and managing access to resources on behalf of a user. It allows two parties, the client and the authorization server, to securely exchange information without revealing sensitive user credentials.
Let's break it down:
Client: This is the application or web page that initiates the authorization process with the authorization server.
Authorization Server: This is a dedicated server that validates the user's identity and grants or denies access based on the granted permissions.
Resource Server: This is the application or website that will be accessed and protected by the authorized client.
How it works:
The client submits a request to the authorization server with requested resources and additional parameters.
The authorization server verifies the client's identity and sends an access token to the client.
The client uses the access token to access the protected resources on behalf of the user.
The client can also use the access token to refresh it when it expires.
Benefits of OAuth 2.0:
Enhanced security: It prevents direct client credentials from being exposed, reducing the risk of unauthorized access.
Standardized: OAuth 2.0 is widely supported by various platforms and applications, facilitating easier integration.
User control: Users can revoke access to their resources at any time through the authorization server.
Examples:
Imagine a web application that allows users to log in with their Google account. When the user clicks the "Login with Google" button, Google redirects the user to Google's authorization server. Google authenticates the user and grants the application access to their Google profile information.
Similarly, when you use a social media platform to log in, the platform redirects you to the platform's authorization server. The platform verifies your identity and grants or denies access based on your granted permissions
