Mobile Identity Connect

Introduction

Mobile Identity Connect (MIC) is a service that bridges mobile applications with existing enterprise identity and single sign-on solutions. MIC enables mobile applications to integrate with a variety of identity solutions using a single OAuth2-based interface. This allows enterprise application developers to avoid the complexity of integrating these protocols into mobile, while providing enterprise IT the means to ensure that access to resources is secured only to authenticated users, as well as maintaining full control over a mobile user's identity.

Core Concepts

MIC Architecture

Mobile Identity Connect Architecture

Mobile Identity Connect (MIC) is the authentication layer for connecting to mobile identity systems. It uses OAuth2 as its underlying identity protocol for connecting client applications. A client application uses OAuth2 to authenticate with the Kinvey Authentication Service. The service provides a login page or redirects to an existing SSO login page, allowing the client user to authenticate.

MIC's architecture enables multi-factor authentication (MFA) for mobile clients during the authentication process by exposing MFA controls through the login page.

Once authenticated, MIC retrieves a token from the underlying identity provider, encrypts it, and securely stores it for use in all future requests to access enterprise resources through Data Link connectors. A Mobile Identity Connect access token is returned to the client, along with an (optional) refresh token.

The client exchanges this token for a Kinvey session token. The Kinvey Cloud Service (KCS) then validates this token with MIC for all future requests from that session token. User credentials are not stored on the device and are never passed directly to KCS.

MIC maintains an internal time-to-live (TTL) for access and refresh tokens which is configured via the Kinvey management console. MIC will re-authenticate the user after the TTL expires which will cause the underlying authentication system to be asked to obtain any tokens again. The TTL should be configured to match the lifetime of the internal authentication.

MIC Architecture with Custom MIC Connector

Mobile Identity Connect Architecture

Mobile Identity Connect offers many out of the box integrations, but when one is not available for your identity provider, you can develop a custom MIC connector to integrate with a host of custom identity systems, such as SSO cookies, database-based authentication, or authentication against a line of business application.

The custom connector sits between Kinvey and the identity system in question. Your adaptor needs to be responsible for verifying the credentials provided from MIC against the identity system. The adaptor is also responsible for obtaining any internal enterprise authentication tokens, such as SSO cookies, SAML assertions, OAuth tokens, or session tokens. Tokens passed back to MIC are stored in the encrypted MIC vault and provided to Kinvey data connectors (if you configure any) during normal Kinvey request processing.

All links controlled by Kinvey are encrypted using TLS. Links not controlled by Kinvey are expected to use TLS encryption for production deployments.

Keep in mind that SSO providers often store their own session data in cookies and logging out of Kinvey will clear the Kinvey session and refresh tokens from the local device. This, in turn, will cause subsequent requests that use these tokens to fail with a 401 Unauthorized response. However, SSO providers may independently retain their sessions through cookies, enabling a user to log in to the Kinvey app again through SSO without re-entering their password.

For instance, using Ping Identity with SAML-Redirect, the user will remain authenticated on the Ping Identity website after logging out of the associated Kinvey application. This would enable a user to log in to their Kinvey app after being logged out.

You need to implement you custom MIC connector as a FlexAuth service and similarly to any other Flex service, you can deploy it either in the Kinvey cloud as an internal Flex service or on infrastructure that you manage as an external Flex service.

Read the Flex Services guide to start off with Flex and the Flex SDK, or go directly to the FlexAuth section to learn how to write an auth service.

Single Sign on across multple Kinvey Mobile Apps

Applications developed with MIC can share authentication credentials between applications hosted on the same device when they use the same Auth Services. An access token granted by Mobile Identity Connect is valid for any environment that is using that specific Auth Service.

Configuring an Auth Service

When two applications share the MIC Auth Services, they can also share the access token between them. This allows a Single Sign On experience for a user on a single device. For example if an enterprise develops an expense reporting application and a separate field service management applications, users of the two apps will only need to log in to either app once to be logged in for both applications. The Kinvey mobile libraries support this feature by storing the access token in secure shared storage on the device. This is configured within Kinvey by using Auth Services on each environment from a shared scope, such as an Organization.

Service Catalog

Configuration of Authentication Services is performed in the Service Catalog of the management console. To configure a connector to an Enterprise Identity Source, click the “Add a Service” button and and select "RapidAuth" from the service types and follow up by selecting the type of connector that you want to configure. This will take you to a configuration page with a form specific to each type of connector. See the following sections for details of each specific type of connector.

An auth-service can be created with a scope of a specific environment or at an Organization level. Organization level Auth-services may be used by any environment belonging to the organization. During configuration, the connector must be associated with an environment by selecting the appropriate application and then the environment. Enterprise customers may also choose to associate the connector with their Organization. A list of one or more connectors can be created for each environment or organization.

Configuring the Environment

Once at least one auth connector has been configured for an environment or an organization, it can be activated by navigating to the Mobile Identity Connect tab of the environment details view.

Environment Mobile Identity Connect

On this page the user can view the set of available services and switch between the environment set or the organization level set, if applicable. Additionally, the default connector can be selected from this view. The default connector is used in the authentication flow if the developer chooses to not specify an auth connector by ID when initiating the authentication flow

Connector Specific Configuration

SAML

Mobile Identity Connect supports SAML SP initiated SSO via POST-POST and Redirect-Post Bindings. Mobile Identity Connect does not support IdP-initiated SSO.

Configuring Kinvey

Configure SAML

In the Kinvey console Auth Service configuration, the following fields should be filled in:

FieldDescriptionRequired?
Type of ProviderAuth Service protocol to use, set this to SAML-Redirect or SAML-POST based on your IdP requirements.Yes

Users of Ping Identity's PingOne service should use the "Initiate Single Sign-On (SSO) URL" that is provided by PingOne when adding Kinvey as an application.

Configuring your SAML Identity Provider to accept Kinvey Requests

When configuring the SAML-Based SSO Identity Provider (IdP), the following information should be used.

Customers with dedicated Kinvey instances and Progress Health Cloud customers need to prepend their Instance ID to the MIC base URL as follows:

https://<instance>-auth.kinvey.com

You can find your Instance ID on the dashboard of the Kinvey Console, next to your App Key and App Secret.

FieldDescriptionValue
entityIdThe unique SAML entityID for MIC.https://auth.kinvey.com/kinvey-mobile-identity-connect
Metadata URIThe single sign-on service URL provided by the SAML Identity Providerhttps://auth.kinvey.com/v2/saml/metadata
Assertion Consumer ServiceThe SAML Assertion URI where SAML assertions will be passed to MIC by the IdPhttps://auth.kinvey.com/v2/saml/assertion/
Logout URLThe SAML logout URIhttps://auth.kinvey.com/v2/saml/logout

Note the version component of the SAML urls. Ensure that this version number "v2" matches the version of the MIC API that is being used from your application. The SAML metadata may vary between versions.

The v1 entityID is kinvey-mobile-identity-connect while the v2+ entityID is https://auth.kinvey.com/kinvey-mobile-identity-connect. The various SAML urls in the metadata will also incorporate the version number.

If the version component is left out of the url, the v1 metadata will be served.

Users of Ping Identity's PingOne service can find a pre-configured link to Kinvey's Moble Identity Connect in the application catalog by searching for "Kinvey".

Kinvey does not directly support SSO Single Logout. The SAML identity provider should be accessed manually if single logout is required.

SAML Assertion Attributes

Kinvey supports the passing of SAML assertions to enterprise data sources through Data Link Connectors. Depending on the security requirements of your organization, different SAML attributes may be required for authorization purposes by your data sources. Mobile Identity Connect is configured to accept any attributes in the SAML assertion, and passes them through to any Data Link Connectors as-is.

OAuth2

Mobile Identity Connect supports Authorization Code and Resource Owner Password Credentials Authorization Grant credential types. See your OAuth2 provider administrator or Section 1.3 of the OAuth2 specification for more details.

Use the Facebook Auth connector instead of the OAuth2 connector to connect to Facebook as an IdP.

Configuring Kinvey

Facebook Auth

Mobile Identity Connect supports version 3.0 of the Facebook Graph API for Identity Provider (IdP) purposes.

Configuring Kinvey

Complete these steps to create and set up a Facebook Auth connector:

  1. In the Kinvey Console, go to the Apps tab and select an app environment.
  2. Go to Identity > Mobile Identity Connect.
  3. Click Add Auth Service.
  4. Select the Facebook Auth type.
  5. Fill in the settings as indicated below and click Save Service.
FieldDescriptionRequired?
NameArbitrary name. Appears in the list of services. Note that duplicate names are allowed.Yes

Client SecretClient secret supplied by Facebook.No
User Id AttributeAttribute name to use as a unique identifier. Once set, changing it can produce duplicate Kinvey user accounts and is not recommended. Overwrites any value set through Unique User Context Field.Yes
Scope (OAuth)User attributes to request from Facebook with the initial authorization request. The user can prohibit Facebook from sending these.No
Unique user context fieldAttribute name from the OAuth access token to use as a unique identifier. If left blank, the username is used. Once set, changing it can produce duplicate Kinvey user accounts and is not recommended. The User ID Attribute value overwrites this value if set.
Grant TTLHow much time the client has to obtain an OAuth access token. Default is 10 s.No
Token TTLHow much time before requiring a new login or token refresh. Default is 3600 s.No
Allow Refresh TokensWhen the OAuth access token expires, you can request a token refresh instead of reauthenticating the user.No
Refresh Token TTLFor how long the refresh tokens is accepted. The user will have to reauthenticate after that. Default is 1209600 s (14 days).No
Allowed AttributesAttributes that the client is allowed to request from Kinvey after Kinvey reads all user data from Facebook. See Attributes and Mappings.Yes
Data Link Header MappingsAllows you to map attributes to custom Kinvey headers. See Attributes and Mappings.Yes

Configuring Facebook

Set your Facebook app to allow a redirect URI used internally by Kinvey. Log in to your Facebook developer account, open the app, go to Facebook Login > Settings> Valid OAuth Redirect URIs, and enter the following URI:

https://auth.kinvey.com/facebook/redirect

Customers with dedicated Kinvey instances and Progress Health Cloud customers need to prepend their Instance ID to the MIC base URL as follows:

https://<instance>-auth.kinvey.com

You can find your Instance ID on the dashboard of the Kinvey Console, next to your App Key and App Secret.

Attributes and Mappings

The Allowed Attributes and Data Link Header Mappings settings in the Kinvey Console connector configuration control how enterprise authentication tokens are sent to a data link connector. The attributes id and audience must be included in this section. Click “Add an allowed attribute, and enter the properties.

Configure Attribute Mappings

To send any of these attributes to a data link connector a Data Link Header Mapping is required. Click “Add a header mapping …” and enter client_token as the key and X-Kinvey-Auth as the value. Data link requests will have a header named X-Kinvey-Auth containing the token as a Base64 encoded string.

Authenticating with Mobile Identity Connect

Clients authenticate with Kinvey’s MIC using the OAuth 2.0 protocol. Complete documentation of the OAuth 2.0 protocol is detailed by the IETF.

Information about Refresh Tokens can be found at http://tools.ietf.org/html/rfc6749#section-1.5.

All OAuth implementations authenticate the user and return a grant code via a redirect callback URI. For native applications (Android, iOS and Xamarin) the Redirect URI can be any valid URI, record the value and use it during the normal OAuth flow. For hybrid applications (PhoneGap, etc) follow the framework guides for intercepting redirects and use the same Redirect URL as specified in the console. For web applications choose the Redirect URL where the web app listens for OAuth grants.

Making MIC Requests

The various authentication flows supported by MIC use the loginWithMIC() or loginWithMICUsingResourceOwnerCredentials() methods of the User class. You will find details on how to use those in the respective sections.

Customers with dedicated Kinvey instances need to set instanceId to the ID of their dedicated Kinvey instance to correctly setup the backend and Mobile Identity Connect API URLs for the library.

You can find your Instance ID on the dashboard of the Kinvey Console, next to your App Key and App Secret.

Kinvey.init({
  appKey: '<Your App Key>',
  appSecret: '<Your App Secret>',
  instanceId: '<Your Instance ID>'
});
Kinvey.init({
  appKey: '<Your App Key>',
  appSecret: '<Your App Secret>',
  instanceId: '<Your Instance ID>'
});

Selecting an Auth Service

The OAuth2 Spec uses the notion of a client identifier to recognize the application that is accessing the identity service. For Kinvey mobile applications, the client id value is either the App Key from the environment or a combination of the App Key and an Auth Service ID value.

The Auth Service Id is displayed on the Auth Service Listing in the MIC section of the environment. See the following image for an example of where to obtain the Auth Service Id.

Auth Service Id Values

If your application only has a single MIC Auth Service configured, you don't need to take additional steps.

When you are using multiple Auth Service configurations, you can control which Auth Service is selected by providing a specific Auth Service ID. If you fail to provide an Auth Service ID, MIC uses the service marked as Default in the Console.

The MIC login functions accept an options object parameter where you can set micId to the Auth Service ID that you want. Specifying an Auth Service ID is always optional.

var promise = Kinvey.User.loginWithMIC('myRedirectURI://',
                Kinvey.AuthorizationGrant.AuthorizationCodeAPI,
                {version: "v2", micId: "52c7159d3d8849538333ee6045346ee7"}
);

Specifying API Version

You may need to change the MIC API version used to authenticate with Mobile Identity Connect to enable some MIC features and authentication flows. The default MIC API version is v3.

The MIC login functions accept an options object parameter where you can set version to the MIC API version that you want. The version that you set only applies to a single login.

Kinvey.User.loginWithMIC('myRedirectURI://',
    Kinvey.AuthorizationGrant.AuthorizationCodeLoginPage,
    { version: 'v2' })
  .then((user: Kinvey.User) => {
    // ...
  })
  .catch((error: Kinvey.BaseError) =>{
    // ...
  });
Kinvey.User.loginWithMIC('myRedirectURI://',
    Kinvey.AuthorizationGrant.AuthorizationCodeLoginPage,
    { version: 'v2' })
  .then(function(user) {
    // ...
  }).catch(function(error ){
    // ...
  });

Authorization Code Grant

The authorization code grant flow of the OAuth2 spec provides a two-step authentication process. In the first step, the user is presented with a server-side login page for authentication. In Kinvey's implementation, that login page can be either provided by Mobile Identity Connect (with or without custom styling) or can be independently created and hosted, with Kinvey acting as the router to that page. The login credentials are forwarded to the underlying authentication source for authentication. Upon successful authentication, a short-lived authorization grant code is generated which can be used to create an access token.

Users requiring multi-factor authentication (MFA) support must use the authorization code grant flow configured to use the authentication providers login page.

In the case of SAML-Redirect, the login page is provided by the SAML IdP. Upon successful authentication, a callback URI is invoked with a grant code included in the query string. The grant code is then exchanged for an access token, which is used to authenticate to Kinvey, and exchanged for a Kinvey token.

Keep in mind that a SSO Provider may maintain its own session state independent of the Kinvey app, and Kinvey apps with a third-party SSO Provider configured may be accessible via the Provider site after Kinvey session tokens have been invalidated (as a new session can simply be created by way of SSO). For instance, using Ping Identity with SAML-Redirect, the user will remain authenticated on Ping Identity website after logging out from the associated Kinvey application. This would enable a user to log in to their Kinvey app after being logged out, i.e. if they remain logged in to Ping Identity.

Initiate the Login Flow

The code snippet below shows how to authenticate a user using a login page with Mobile Identity Connect. This will present the login page as a popup to the user where they can enter their credentials. If the popup is blocked, the promise will be rejected with the appropriate error. After the user is successfully authenticated, the login process will complete resolving the promise with the authenticated user. If an error occurs at any point in the authentication process the promise will be rejected with an error containing details of the error that occurred.

Kinvey.User.loginWithMIC('myRedirectURI://')
  .then((user: Kinvey.User) => {
    // ...
  })
  .catch((error: Kinvey.BaseError) => {
    // ...
  });
Kinvey.User.loginWithMIC('myRedirectURI://')
  .then(function(user) {
    // ...
  })
  .catch(function(error) {
    // ...
  });

The loginWithMIC() method will first look for a redirect URI inside your package.json configuration file, meaning that you can omit the method argument if you have configured package.json accordingly. The package.json setting that sets the redirect URI is called redirectUri and falls under the kinvey-nativescript-sdk section.

"pluginsData": {
  "kinvey-nativescript-sdk": {
    "config": {
      "appKey": "kid_S...--qCb",
      "appSecret": "d0b8e416e3e...e1987f5945315b8906",
      "redirectUri":"myRedirectURI://"
    }
  }
}

You need to pass the string argument only if you haven't specified a redirect URI in package.json or if you want to call the method with another redirect URI. In both cases, you need to register the URI as a custom scheme. The steps depend on the OS.

On Android, add an intent filter in your manifest:

<activity ...>
    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="myRedirectURI" />
    </intent-filter>
</activity>

On iOS, register your custom scheme in your app's Info.plist. Either edit the file in a plain-text editor as shown below or use the Xcode editor.

<key>CFBundleURLTypes</key>
 <array>
   <dict>
     <key>CFBundleURLName</key>
     <string>com.example.myapp</string>
     <key>CFBundleURLSchemes</key>
     <array>
       <string>myRedirectURI</string>
     </array>
   </dict>
 </array>

Resource Owner Credentials Grant (Username and Password)

The resource owner credentials grant flow allows an app to send credentials (username and password) directly to the token endpoint. It consists of a single request to obtain a token from the MIC Token endpoint.

The resource owner credentials grant flow requires the security trade-off of trusting the app to handle the credentials securely. With it, the user inputs a username and a password into the app, which exchanges the credentials for an access token. The Authorization Code Grant flow is the recommended flow because is never requires that the user trust the application with their credentials.

The Resource Owner Credentials Grant flow supports LDAP, Active Directory, OAuth2, and Custom Auth Services.

Initiate the Login Flow

To initiate an MIC login as part of the Resource Owner Credentials Grant flow, call the loginWithMICUsingResourceOwnerCredentials() method, passing the username and password combination.

var promise = Kinvey.User.loginWithMICUsingResourceOwnerCredentials(
        username,
        password
    );
promise = promise.then(function onSuccess(user) {
  // ...
}).catch(function onError(error) {
  // ...
});
