![]() ![]() Do we select it randomly? No, we need to know how tokens are created in each of the grant types. When starting an implementation, we need to choose our grant. Here are the most common OAuth 2 grants you can choose from: We call these ways to obtain the token grants. Once you obtain a token, you can access specific resources, but OAuth 2 offers multiple possibilities for obtaining the token. Mainly, OAuth 2 refers to using tokens for authorization. How does OAuth 2 work then? What does it mean to implement OAuth 2 authentication and authorization? It’s important to do this before starting with the first implementation to know what you’re implementing. I’ll take the most common cases and evaluate them. As you’ll learn, OAuth 2 implies multiple possible authentication flows, and you need to know which one applies to your case. In this section, we discuss how to apply OAuth 2, depending on the architecture of your application. The resource server allows the Client to access the resource they requested if the Client has a valid token. The Client uses this token to prove to the resource server that it was authorized by the authorization server. When the authorization server decides that a client is authorized to access a resource on behalf of the user, it issues a token. The authorization server – the application which authorizes the Client to access the users’ resources exposed by the resource server.The Client needs its own credentials to identify itself when making a request. Be careful, these credentials are not the same as the user’s credentials. The Client uses a client ID and a client secret to identify itself. The Client – an application that accesses the resources owned by the user, on behalf of the user.A user generally has a username and a password which they use to identify themselves. The user (also known as the resource owner) – This is the individual who owns resources exposed by the resource server.Resources can be users’ data or actions they are authorized to do. The resource server – The application hosting resources owned by users.Each of them has its own responsibility, essential in the authentication and authorization process. The main components of the OAuth 2 architecture are the resource owner, the Client, the authorization server, and the resource server. In this article, we only discuss what these components are, and their purpose (figure 1).įigure 1.
