What is OAuth and how do I use it with APIs?

OAuth is an open standard for access delegation, commonly used for token-based authentication. It allows third-party services to exchange information without sharing passwords.

Can you explain the steps to implement OAuth in my application?

Sure! First, you need to register your application with the service provider to get client credentials. Then, implement the authorization flow, which typically involves redirecting users to the provider's login page.

What are the different OAuth flows I should know about?

The main OAuth flows are Authorization Code Flow, Implicit Flow, Resource Owner Password Credentials Flow, and Client Credentials Flow. Each is suited for different types of applications.

Are there any libraries you recommend for implementing OAuth?

Yes! Popular libraries include OAuth2 Client for Python, Spring Security OAuth for Java, and Passport.js for Node.js. They simplify the implementation process.
