Editing Understanding OAuth 2.0: Token-Based Authorization (section)

== Key Components of OAuth 2.0 ==

OAuth 2.0 involves multiple components, including:
# '''Resource Owner''': The user who owns the data and grants permission to access it.
# '''Client''': The application requesting access to the user’s resources.
# '''Authorization Server''': The server that authenticates the user and issues tokens.
# '''Resource Server''': The API or service that holds the protected resources and verifies tokens.
# '''Access Token''': A token issued by the authorization server that allows the client to access the resource server.
# '''Refresh Token''': A long-lived token used to request new access tokens without requiring user authentication again.
