OAuth 2 overview

This article assumes that readers are familiar with OAuth 2. However, below a brief description of it is presented below.

1. The application requests authorization to access service resources from the user. The application needs to provide the client ID, client secret, redirect URI and the required scopes.
2. If the user authorizes the request, the application receives an authorization grant
3. The application requests an access token from the authorization server by presenting authentication of its own identity, and the authorization grant
4. If the application identity is authenticated and the authorization grant is valid, the authorization server issues the access and refresh (if required) token to the application. Authorization is complete.
5. The application requests the resource from the resource server and presents the access token for authentication
6. If the access token is valid, the resource server serves the resource to the application

The are some main Pros and Cons in OAuth 2.0

• OAuth 2.0 is easier to use and implement (compared to OAuth 1.0)
• Wide spread and continuing growing
• Short lived Tokens
• Encapsulated Tokens

— No signature (relies solely on SSL/TLS ), Bearer Tokens
— No built-in security
— Can be dangerous if used from not experienced people
— Too many compromises. Working group did not make clear decisions
— Mobile integration (web views)
— Oauth 2.0 spec is not a protocol, it is rather a framework — RFC 6749
