How-tos
Device Authorization Grant
The OAuth 2.0 Device Authorization Grant solves the problem of authenticating a user on a device that does not have user friendly input capabilities. Authentication instead takes place out-of-band on a different device.
User consent
Handling user consent for claims
Resource Owner Password Flow
This tutorial explains how to use the Resource Owner Password Credential Flow (ROPC) to obtain tokens from the Curity Identity Server
Revoking OAuth Tokens
Learn how to revoke access and refresh tokens issued according to the OAuth standard
Refresh Tokens
This tutorial explains how to issue Refresh Tokens in the Curity Identity Server, control their lifetime, include/exclude them for certain clients, and use them to get new access tokens
Client Credentials Flow
OAuth has a flow called client credentials, that comes in handy when there are requests to your APIs that are not involving a user. Using the Client Credentials flow, it's possible to let servers communicate with your API without modifying the APIs themselves.
Hybrid Flow
This tutorial explains how to obtain an OAuth access token using the hybrid flow. The guide includes step by step instructions for how to set it up and configure it in the Curity Identity Server.
Implicit Flow
Using the OAuth 2 Implicit Flow
Code Flow
This tutorial explains how to obtain an OAuth access token using the code flow, a popular message exchange pattern used by server-based applications. The guide includes step by step instructions for how to set it up and configure it in the Curity Identity Server.

OAuth 2.0 is the industry-standard protocol for authorization and access delegation. It specifies a process for resource owners to authorize third-part access to their resources without sharing their credentials. OAuth facilitates fast and secure authentication and authorization for users to APIs, servers, devices and apps. It does this without sharing password information and instead uses access tokens to prove an identity, keeping user credentials safe.
