IdentityManager
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 Use a proxy 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.

Number | The suggested lifetime of the token in minutes. more details | more details | IdentityManagerBase | |
Boolean | If your application is on the same domain as *.arcgis.com or ArcGIS Enterprise Server, the IdentityManager will redirect the user to its sign-in page. more details | more details | IdentityManagerBase |
Property Details
- dialogDialog
Dialog box widget used to challenge the user for their credentials when the application attempts to access a secure resource. This property is available after the dialog-create event has fired.
The suggested lifetime of the token in minutes.
- Default Value:60
If your application is on the same domain as *.arcgis.com or ArcGIS Enterprise Server, the IdentityManager will redirect the user to its sign-in page. For instance, let's say an application accesses secure resources from ArcGIS.com or one of its subdomains. Once the application attempts to access this resource, the IdentityManager redirects the user to the ArcGIS.com sign-in page. Once a user successfully logs in, they are redirected back to the application. The same holds true if the application accesses secure resources from ArcGIS Enterprise as the IdentityManager will redirect the user to its sign-in page. If you do not wish for the application to automatically redirect, set this property to
false
. (Please note that this is not a common scenario. For most, using the OAuth sign-in behavior should handle most of their authentication needs.)- Default Value:true

method that can be called to stop listening for the event.Property Type Description remove Function When called, removes the listener from the event. - See also:
Example:view.on("click", function(event){ // event is the event handle returned after the event fires. console.log(event.mapPoint); });
- registerOAuthInfos(oAuthInfos)inherited
Registers OAuth 2.0 configurations.
Parameter:oAuthInfos OAuthInfo[]An array of OAuthInfo objects that defines the OAuth configurations.
Example:require(["esri/identity/OAuthInfo", "esri/identity/IdentityManager"], function(OAuthInfo, esriId) { var oAuthInfo = new OAuthInfo({ appId: "<registered client id>" }); // required parameter esriId.registerOAuthInfos([oAuthInfo]); });
- registerServers(serverInfos)inherited
Register secure servers and the token endpoints.
Parameter:serverInfos 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.
Example:require(["esri/identity/ServerInfo", "esri/identity/IdentityManager"], function(serverInfo, esriId) { var serverInfo = new ServerInfo(); serverInfo.server = "http://sampleserver6.arcgisonline.com"; serverInfo.tokenServiceUrl = "http://sampleserver6.arcgisonline.com/arcgis/tokens/generateToken"; esriId.registerServers([serverinfo]); });
- registerToken(properties)inherited
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. See also resource-proxy for another workflow to achieve this result.Once a user logs in, the access token is registered with the IdentityManager. Subsequently, every AJAX request made by the application forwards this token when accessing web maps and other items stored in ArcGIS Online, or resources on your server.
Parameters:properties ObjectSee the table below for the structure of the properties object.
Specification:expires 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.
- setOAuthRedirectionHandler(handlerFunction)
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.
Parameter:handlerFunction handlerCallbackWhen called, the callback passed to
setOAuthRedirectionHandler
receives an object containing the redirection properties.Example:require(["esri/identity/IdentityManager"], function(esriId) { esriId.setOAuthRedirectionHandler(function(info) { // Execute custom logic then perform redirect window.location = info.authorizeUrl + "?" + ioquery.objectToQuery(info.authorizeParams); }); });
- setOAuthResponseHash(hash)
Use this method in the popup callback page to pass the token and other values back to the IdentityManager.
Parameter:hash StringThe token information in addition to any other values needed to be passed back to the IdentityManager.
- setProtocolErrorHandler(handlerFunction)inherited
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.
Parameters:handlerFunction FunctionThe function to call when the protocol is mismatched.
Specification:resourceUrl StringThe secure resource URL.
serverInfo ServerInfoServerInfo object describing the server where the secure resource is hosted.
- setRedirectionHandler(handlerFunction)inherited
If your application is on the same domain as *.arcgis.com or ArcGIS Enterprise Server, the IdentityManager will redirect the user to its sign-in page. For instance, let's say an application accesses secure resources from ArcGIS.com or one of its subdomains. Once the application attempts to access this resource, the IdentityManager redirects the user to the ArcGIS.com sign-in page. Once a user successfully logs in, they are redirected back to the application. The same holds true if the application accesses secure resources from ArcGIS Enterprise as the IdentityManager will redirect the user to its sign-in page. Use this method if the application needs to execute custom logic before the page is redirected by creating a custom redirection handler. The IdentityManager calls the custom handler function with an object containing the redirection properties.
Parameters:handlerFunction FunctionThe function passed to setRedirectionHandler receives an object containing redirection properties. These properties are listed in the table below.
Specification:resourceUrl StringThe URL of the secure resource that triggers the redirection to the ArcGIS.com sign-in page.
returnUrlParamName StringThe application URL where the sign-in page redirects after a successful login. To create the return URL, append the application's URL to signInPage as a parameter. The returnUrlParamName contains the name of the parameter.
serverInfo ServerInfoThe ServerInfo object describing the server where the secure resource is hosted.
signInPage StringURL of the sign-in page where users will be redirected.
Example:require(["esri/IdentityManager"], function(esriId) { esriId.setRedirectionHandler(function(info) { // Execute custom logic then perform redirect window.location = info.signInPage "?" info.returnUrlParamName "=" window.location.href; }); });
Subclasses must implement this method to create and manage the user interface used to obtain a username and password from the end user. It should perform the following tasks:
- challenge the user for a username and password,
- generate a token and return it to the caller.
Parameters:url StringURL for the secured resource.
serverInfo ServerInfoA ServerInfo object that contains the token service URL.
options ObjectoptionalSee the table below for the structure of the options object.
Specification:error ErrorError object returned by the server from a previous attempt to fetch the given URL.
Returns:Type Description Promise<Object> Resolves to an object containing a token.
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.
Returns:Type Description Object The JSON object representing the IdentityManager instance calling this method.
Type Definitions
- handlerCallback(authorizeParams, authorizeUrl, oAuthInfo, resourceUrl, serverInfo)
The callback to execute when setOAuthRedirectionHandler() is called.
Parameters:authorizeParams ObjectObject containing authorization parameters used to access the secure service. See the table below describing the properties of this object.
Specification:client_id StringThe application ID of the registered application.
response_type StringThe type of response returned.
state StringThe state parameter passed back as the object in the Credential's oAuthState property.
expiration NumberThe expiration time in minutes.
locale StringThe locale being used.
redirect_uri StringThe redirect URL represents the valid places that a user can be redirected to after a successful sign in.
authorizeUrl StringThe OAuth 2.0 authorization URL for the portal.
oAuthInfo OAuthInfoA reference to the OAuthInfo object.
resourceUrl StringThe URL to the accessed resource.
serverInfo ServerInfoThe ServerInfo object describing the server where the secure resource is hosted.
