How to implement REST token-based authentication with JAX-RS and Jersey, What is the Access Token vs. Access Token Secret and Consumer Key vs. Consumer Secret. Note that we only got the username of the account in the example, but since the AS does the authentication, it can also return additional claims in this response (things like account type, address, shoe-size, etc.) Tokens could allow this. That means that the same key has to be both on the client and the server to be able to authenticate users. Also identity provider typically allow for multiple users / service users / service principles so its easier to audit consumers. Looks like you have Javascript turned off! Try it, you can cancel anytime with a single click. OAuth is a delegated authorization framework for REST/APIs. This often require cryptographic operation which gives headache to the average software engineer. The API key only identifies the application, not the user of the application. Internet Engineering Task Force. For the reference token, the service will have to send a request to the AS to validate the token and return the data associated with it. This token can be signed or encrypted so that the service can verify the token by simply using the public key of the trusted AS. Lets consider security with APIs, i.e how to securely identify the caller. Daniel Lindau is a Solution Architect at Curity. Why is OAuth more secure?

The previous versions of this spec, OAuth 1.0 and 1.0a, were much more complicated than OAuth 2.0. The server then validates them based on values registered in its credentials database. When a user is authenticated, the application is required to collect the password. Session based authentication: Because the sessions are stored in the server's memory, scaling becomes an issue when there is a huge number of users using the system at once. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, Good answer, but it should be mentionned that OAuth2 itself cannot be used to authenticate users (the client knows nothing about the user unless an API endpoint is available). Whats the difference between form based authentication Vs Oauth 2.0? In access management, servers use token authentication to check the identity of a user, an API, a computer, or another server. OAuth performs authorization, to determine what an app can do. Most developers pick up the techniques quickly, but there is a learning curve.
