What are the key features of OAuth 2.0?

OAuth 2.0 is an authorization framework that allows third-party applications to obtain limited access to user accounts. Key features include:

1. Delegated Access: Users can grant access to their resources without sharing credentials.
2. Token-Based Authentication: Uses access tokens instead of credentials for secure access.
3. Scopes: Allows users to specify the level of access granted to applications.
4. Refresh Tokens: Enables applications to obtain new access tokens without user intervention.

How does OAuth 2.0 improve security?

OAuth 2.0 improves security by minimizing the need for users to share their passwords with third-party applications. Instead, it uses access tokens that can be limited in scope and duration, reducing the risk of credential theft.

Can you explain the difference between access tokens and refresh tokens?

Sure! Access tokens are short-lived tokens used to access resources, while refresh tokens are long-lived tokens used to obtain new access tokens without requiring user re-authentication.

What are some common use cases for OAuth 2.0?

Common use cases include social media logins, API access for mobile apps, and integrating third-party services like payment gateways.
