What are the different OAuth 2.0 authorization grant types?

OAuth 2.0 defines several authorization grant types, including Authorization Code, Implicit, Resource Owner Password Credentials, and Client Credentials.

Can you explain the Authorization Code grant type?

Sure! The Authorization Code grant type is used for server-side applications. It involves redirecting the user to the authorization server to obtain an authorization code, which is then exchanged for an access token.

What about the Implicit grant type?

The Implicit grant type is designed for client-side applications, where the access token is returned directly in the URL after user authorization, without an intermediate authorization code.

When should I use the Resource Owner Password Credentials grant?

This grant type is suitable for trusted applications where the user can provide their credentials directly to the application, but it's less secure and not recommended for third-party apps.
