Client

The Client class models an OpenID Connect or OAuth 2.0 client - e.g. a native application, a web application or a JS-based application.

Basics

Enabled
Specifies if client is enabled. Defaults to true.
ClientId
Unique ID of the client
ClientSecrets
List of client secrets - credentials to access the token endpoint.
RequireClientSecret
Specifies whether this client needs a secret to request tokens from the token endpoint (defaults to true)
RequireRequestObject
Specifies whether this client needs to wrap the authorize request parameters in a JWT (defaults to false)
AllowedGrantTypes
Specifies the grant types the client is allowed to use. Use the GrantTypes class for common combinations.
RequirePkce
Specifies whether clients using an authorization code based grant type must send a proof key (defaults to true).
AllowPlainTextPkce
Specifies whether clients using PKCE can use a plain text code challenge (not recommended - and default to false)
RedirectUris
Specifies the allowed URIs to return tokens or authorization codes to
AllowedScopes
By default a client has no access to any resources - specify the allowed resources by adding the corresponding scopes names
AllowOfflineAccess
Specifies whether this client can request refresh tokens (be requesting the offline_access scope)
AllowAccessTokensViaBrowser
Specifies whether this client is allowed to receive access tokens via the browser. This is useful to harden flows that allow multiple response types (e.g. by disallowing a hybrid flow client that is supposed to use code id_token to add the token response type and thus leaking the token to the browser.
Properties
Dictionary to hold any custom client-specific values as needed.

Authentication/Logout

PostLogoutRedirectUris
Specifies allowed URIs to redirect to after logout. See the OIDC Connect Session Management spec for more details.
FrontChannelLogoutUri
Specifies logout URI at client for HTTP based front-channel logout. See the OIDC Front-Channel spec for more details.
FrontChannelLogoutSessionRequired
Specifies if the user’s session id should be sent to the FrontChannelLogoutUri. Defaults to true.
BackChannelLogoutUri
Specifies logout URI at client for HTTP based back-channel logout. See the OIDC Back-Channel spec for more details.
BackChannelLogoutSessionRequired
Specifies if the user’s session id should be sent in the request to the BackChannelLogoutUri. Defaults to true.
EnableLocalLogin
Specifies if this client can use local accounts, or external IdPs only. Defaults to true.
IdentityProviderRestrictions
Specifies which external IdPs can be used with this client (if list is empty all IdPs are allowed). Defaults to empty.
UserSsoLifetime added in 2.3
The maximum duration (in seconds) since the last time the user authenticated. Defaults to null. You can adjust the lifetime of a session token to control when and how often a user is required to reenter credentials instead of being silently authenticated, when using a web application.

Token

IdentityTokenLifetime
Lifetime to identity token in seconds (defaults to 300 seconds / 5 minutes)
AllowedIdentityTokenSigningAlgorithms
List of allowed signing algorithms for identity token. If empty, will use the server default signing algorithm.
AccessTokenLifetime
Lifetime of access token in seconds (defaults to 3600 seconds / 1 hour)
AuthorizationCodeLifetime
Lifetime of authorization code in seconds (defaults to 300 seconds / 5 minutes)
AbsoluteRefreshTokenLifetime
Maximum lifetime of a refresh token in seconds. Defaults to 2592000 seconds / 30 days
SlidingRefreshTokenLifetime
Sliding lifetime of a refresh token in seconds. Defaults to 1296000 seconds / 15 days
RefreshTokenUsage

ReUse the refresh token handle will stay the same when refreshing tokens

OneTime the refresh token handle will be updated when refreshing tokens. This is the default.

RefreshTokenExpiration

Absolute the refresh token will expire on a fixed point in time (specified by the AbsoluteRefreshTokenLifetime). This is the default.

Sliding when refreshing the token, the lifetime of the refresh token will be renewed (by the amount specified in SlidingRefreshTokenLifetime). The lifetime will not exceed AbsoluteRefreshTokenLifetime.

UpdateAccessTokenClaimsOnRefresh
Gets or sets a value indicating whether the access token (and its claims) should be updated on a refresh token request.
AccessTokenType
Specifies whether the access token is a reference token or a self contained JWT token (defaults to Jwt).
IncludeJwtId
Specifies whether JWT access tokens should have an embedded unique ID (via the jti claim). Defaults to true.
AllowedCorsOrigins
If specified, will be used by the default CORS policy service implementations (In-Memory and EF) to build a CORS policy for JavaScript clients.
Claims
Allows settings claims for the client (will be included in the access token).
AlwaysSendClientClaims
If set, the client claims will be sent for every flow. If not, only for client credentials flow (default is false)
AlwaysIncludeUserClaimsInIdToken
When requesting both an id token and access token, should the user claims always be added to the id token instead of requiring the client to use the userinfo endpoint. Default is false.
ClientClaimsPrefix
If set, the prefix client claim types will be prefixed with. Defaults to client_. The intent is to make sure they don’t accidentally collide with user claims.
PairWiseSubjectSalt
Salt value used in pair-wise subjectId generation for users of this client.

Device flow

UserCodeType
Specifies the type of user code to use for the client. Otherwise falls back to default.
DeviceCodeLifetime
Lifetime to device code in seconds (defaults to 300 seconds / 5 minutes)
