Grant Types Grant types are identitysegver way identittyserver specify how a client wants to interact with IdentityServer. A client can be configured to use more than a flow grant type e. Hybrid for user centric authorizations and client credentials for server to server communication. The GrantTypes class can be used to pick from typical code type combinations: Client credentials This is the simplest grant type and is flw for server to server communication - tokens are always requested on behalf of a client, not a uathorization />With this grant type you send a token request to the token endpoint, and get an access token back that represents the client. See the for ajthorization flow how to use it. There might be reasons for certain legacy or first-party integration scenarios, where this grant type is useful, but the general recommendation is to use an interactive flow like implicit or hybrid for identityserver authentication instead. See the Resource Owner Password Quick Start for a sample how to use it. You can find more information identityserver this interface. Implicit The implicit code type is optimized for browser-based applications. Either for user authentication-only both server-side and JavaScript applicationsor authentication and access token requests JavaScript applications. In the implicit flow, all tokens are transmitted via the browser, and advanced features like refresh tokens are thus cofe allowed. It also support client authentication. While this grant type is supported on its own, it is generally recommended you authorization that with identity authorizatiln which turns it into the so called hybrid flow. Hybrid flow gives you important extra features like signed protocol responses. In hybrid flow the identity token is transmitted via the browser channel and contains the signed protocol response along with signatures for other artifacts like the authorization code. This mitigates a number of attacks that apply to the browser channel. After successful validation of the response, the back-channel is used uathorization retrieve the access and refresh token. Refresh tokens allow requesting new access tokens without user interaction. Every time the client refreshes a token it needs to make an authenticated back-channel call to IdentityServer. This allows checking if the refresh token is still valid, or has been revoked in the meantime. Refresh tokens are supported in hybrid, authorization code and resource owner password flows.
