esri/identity/IdentityManager
This object provides the framework and helper methods used in managing user credentials for the following resources:
-
Secured ArcGIS.com or ArcGIS Enterprise portal resources (e.g. web maps).
-
ArcGIS Server resources secured using token-based authentication. Note that only ArcGIS Server versions 10 SP 1 and greater are supported. If your application accesses services from different domains, it is deemed a cross-domain request and you need to setup a proxy or use CORS (if supported by browser). If CORS is supported, the Identity Manager knows to make a request to the token service over https.
Authentication requests over http are prevented because sensitive data sent via GET can be viewed in server logs. To prevent this, the Identity Manager requires that you use POST over https to ensure your credentials are secure. View the proxy pages and CORS help topic for more details.
The IdentityManager module is slightly different than other modules in the API. Instead of returning a class constructor, it returns a singleton instance that has already been created by this module.

Method Details
-
Since: ArcGIS Maps SDK for JavaScript 4.10IdentityManager since 4.0, checkAppAccess added at 4.10. -
Returns a credential if the user has already signed in to access the given resource and is allowed to do so when using the given application id. In addition, it also returns a
boolean
,viewOnly
, property that indicates whether the app is only viewable. The default isfalse
. If the user has not signed in or does not have access, then the promise will be rejected and its error callback will be called.This scenario is generally not common unless you are building a licensed app. Also, please note that this method should only be used if your application is on the same domain as
*.arcgis.com
or ArcGIS Enterprise Server and is only applicable to applications registered as items in theEsri
organization.ReturnsType Description Promise<object> Resolves to an object which contains the following properties: Property Type Description credential Credential The credential of the user. viewOnly boolean Indicates whether the app is only viewable. Default is false
.
-
checkSignInStatus
checkSignInStatus(resUrl){Promise<Credential>}
-
Returns the Credential if the user has already signed in to access the given resource. If the user has not signed in, then the promise will be rejected and its error callback will be called.
ParameterresUrl StringThe resource URL.
ReturnsType Description Promise<Credential> Resolves to the returned credential of the signed-in user.
-
Destroys all credentials. It is good practice to call this method if working with an application that contains sign-out functionality as any tokens generated via OAuth will automatically be revoked.
-
Since: ArcGIS Maps SDK for JavaScript 4.19IdentityManager since 4.0, disablePostMessageAuth added at 4.19. -
Disables the use of
window.postMessage
to serve authentication requests that were enabled by enablePostMessageAuth. This should be called to prevent memory leaks in SPA routing apps when they need to transition routes. Setting this this helps clean up and remove anywindows's
message
event listeners that enablePostMessageAuth added.Please refer to the topic, Passing authentication to IFramed apps for additional information. The main differences are:
- The ArcGIS REST JS API's enablePostMessageAuth method's signature is different than what is provided in the ArcGIS Maps SDK for JavaScript as explained here.
- Step three, i.e.
Embed App boots and Requests Auth
, does not apply when using the ArcGIS Maps SDK for JavaScript.
-
Since: ArcGIS Maps SDK for JavaScript 4.19IdentityManager since 4.0, enablePostMessageAuth added at 4.19. -
Enables the IdentityManager to serve authentication requests for the given resource from apps running in child iframes. The only apps that will be allowed to request the credential are ones that are either running at
*.arcgis.com
, or are running at the same origin as the host app. Requests from other apps will be ignored.Only one resource may be authenticated in this manner at any one time. The URL of the resource should be used as the value of a parameter named
arcgis-auth-portal
that is included in the iframe'ssrc
URL. The iframe'ssrc
URL should also include another parameter namedarcgis-auth-origin
with a value ofwindow.location.origin
. Both of these parameter values should be URL-encoded usingencodeURIComponent
. These parameters are used by the IdentityManager, or the UserSession running in the iframe app when it needs the user's authentication to access a given resource.Please refer to the topic, Passing authentication to IFramed apps for additional information. The main differences are:
- The ArcGIS REST JS API's enablePostMessageAuth method's signature is different than what is provided in the ArcGIS Maps SDK for JavaScript as explained here.
- Step three, i.e.

Registers an event handler on the instance. Call this method to hook an event with a listener.
ParametersReturnsType Description Object Returns an event handler with a remove()
method that should be called to stop listening for the event(s).Property Type Description remove Function When called, removes the listener from the event. Exampleview.on("click", function(event){ // event is the event handle returned after the event fires. console.log(event.mapPoint); });
-
Registers OAuth 2.0 configurations.
ParameterExamplerequire(["esri/identity/OAuthInfo", "esri/identity/IdentityManager"], function(OAuthInfo, esriId) { let oAuthInfo = new OAuthInfo({ appId: "<registered client id>" }); // required parameter esriId.registerOAuthInfos([oAuthInfo]); });
-
Register secure servers and the token endpoints.
ParameterserverInfos ServerInfo[]An array of ServerInfos objects that defines the secure service and token endpoint. The IdentityManager makes its best guess to determine the location of the secure server and token endpoint. Therefore, in most cases calling this method is not necessary. However, if the location of your server or token endpoint is not standard, use this method to register the location.
Examplerequire(["esri/identity/ServerInfo", "esri/identity/IdentityManager"], function(ServerInfo, esriId) { let serverInfo = new ServerInfo(); serverInfo.server = "https://sampleserver6.arcgisonline.com"; serverInfo.tokenServiceUrl = "https://sampleserver6.arcgisonline.com/arcgis/tokens/generateToken"; serverInfo.hasServer = true; esriId.registerServers([serverInfo]); });
-
Registers the given OAuth 2.0 access token or ArcGIS Server token with the IdentityManager. See registerOAuthInfos for additional information. The
registerToken
method is an advanced workflow for pre-registering long-term tokens for when you don't want users to sign in.Once a user logs in, the access token is registered with the IdentityManager. Subsequently, every request made by the application forwards this token when accessing web maps and other items stored in ArcGIS Online, or resources on your server.
ParametersSpecificationproperties ObjectSee the table below for the structure of the properties object.
Specificationexpires NumberoptionalToken expiration time specified as number of milliseconds since 1 January 1970 00:00:00 UTC.
server StringFor ArcGIS Online or Portal, this is https://www.arcgis.com/sharing/rest or similar to https://www.example.com/portal/sharing/rest. For ArcGIS Server this is similar to https://www.example.com/arcgis/rest/services.
ssl BooleanoptionalSet this to
true
if the user has an ArcGIS Online organizational account and the organization is configured to allow access to resources only through SSL.token StringThe access token.
userId StringoptionalThe id of the user who owns the access token.
-
Once a user successfully logs in, they are redirected back to the application. Use this method if the application needs to execute custom logic before the page is redirected. The IdentityManager calls the custom handler function with an object containing redirection properties.
ParameterhandlerFunction handlerCallbackWhen called, the callback passed to
setOAuthRedirectionHandler
receives an object containing the redirection properties.Examplerequire(["esri/identity/IdentityManager"], function(esriId) { esriId.setOAuthRedirectionHandler(function(info) { // Execute custom logic then perform redirect window.location = info.authorizeUrl + "?" + ioquery.objectToQuery(info.authorizeParams); }); });
-
Use this method in the popup callback page to pass the token and other values back to the IdentityManager.
Parameterhash StringThe token information in addition to any other values needed to be passed back to the IdentityManager.
-
When accessing secured resources, the IdentityManager may prompt for username and password and send them to the server using a secure connection. Due to potential browser limitations, it may not be possible to establish a secure connection with the server if the application is being run over HTTP protocol. In such cases, the Identity Manager will abort the request to fetch the secured resource. To resolve this issue, configure your web application server with HTTPS support and run the application over HTTPS. This is the recommended solution for production environments. However, for internal development environments that don't have HTTPS support, you can define a protocol error handler that allows the Identity Manager to continue with the process over HTTP protocol.
ParametersSpecificationhandlerFunction FunctionThe function to call when the protocol is mismatched.
SpecificationresourceUrl StringThe secure resource URL.
serverInfo ServerInfoServerInfo object describing the server where the secure resource is hosted.
-
toJSON
toJSON(){Object}
-
Return properties of this object in JSON format. It can be stored in a cookie or persisted in HTML5 LocalStorage and later used to:
- Initialize the IdentityManager the next time a user opens your application.
- Share the state of the IdentityManager between multiple web pages of your website. This way users will not be asked to sign in repeatedly when they launch your app multiple times or when navigating between multiple web pages in your website.
ReturnsType Description Object The JSON object representing the IdentityManager instance calling this method.
Type Definitions
