The tutorial explains the OAuth flow, including the roles of resource owner, resource server, client, and authorization server. It discusses scopes, which define permissions requested by applications, and the use of access and refresh tokens for secure API access. An example of an OAuth request using Gmail's API is also provided, illustrating the process of obtaining authorization codes and tokens.
