Upgrade to Okta Identity Engine

Enable OIE for your organization

To upgrade to Okta Identity Engine, please reach out to your account manager. If you do not have an account manager, please reach out to oie@okta.com for more information.

Enable interaction code grant

After the Okta Identity Engine feature is enabled for your org, it should become active for Okta-hosted sign-in flows that don't involve an OAuth application. Enabling the interaction_code grant type allows OAuth applications to use the Okta Identity Engine.

Enable interaction code grant on an authorization server

  1. Navigate to Security > API > Authorization Servers in the Admin Console.
  2. Select an authorization server and click the edit icon.
  3. Click the Access Policies tab.
  4. Edit the Default Policy Rule.
  5. In the IF Grant type is section, click the Interaction Code check box.

Enable interaction code grant on an application

  1. Navigate to Applications > Applications in the Admin Console.
  2. Click an application in the list.
  3. Click the General tab on the application detail.
  4. Click edit on the General Settings panel.
  5. In the Allowed grant types section, click the Interaction Code check box.

Web clients

Okta-hosted sign-in page (default)

For most authentication flows that involve redirecting to Okta, there should be no other changes needed. Once the feature is enabled, the Okta Identity Engine will be used automatically, by default.

Customized sign-in page / custom domain

For most users of the custom domain feature, there are no other changes needed. The default template detects and uses the Okta Identity Engine automatically.

However, if you have modified the template in certain ways (such as to perform redirects or set cookies), these modifications may not be compatible with the Okta Identity Engine. In particular, these methods and objects won't work with OIE:

  • setCookieAndRedirect
  • sessionToken

In the default template, the success callback from renderEl is being handled by OktaUtil.completeLogin. This method correctly handles the authentication flow, and we recommend using it.

For reference, here is the default template:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta name="robots" content="none" />

    <div class="login-bg-image" style="background-image: {{bgImageUrl}}"></div>
    <div id="okta-login-container"></div>

        "OktaUtil" defines a global OktaUtil object
        that contains methods used to complete the Okta login flow.

    <script type="text/javascript">
        // "config" object contains default widget configuration
        // with any custom overrides defined in your admin settings.
        var config = OktaUtil.getSignInWidgetConfig();

        // Render the Okta Sign-In Widget
        var oktaSignIn = new OktaSignIn(config);
        oktaSignIn.renderEl({ el: '#okta-login-container' },
            function(error) {
                // Logs errors that occur when configuring the widget.
                // Remove or replace this with your own custom error handler.
                console.log(error.message, error);

Embedded Sign-In Widget

Note: "Embedded" means the Sign-In Widget is included directly in your application through npm module or script tag. The @okta/okta-signin-widget version 5.2.0 or above is needed to enable the interaction code flow.

Set the option useInteractionCodeFlow to true on the object passed to the Sign-In Widget constructor. This enables Okta Identity Engine for the Widget. Both the authorization server and the application must have the interaction code grant type enabled.

Note: Your code may break if it is calling the renderEl method and expects sessionToken or session.setCookieAndRedirect on the response object. Instead of renderEl, we recommend calling the showSignInToGetTokens method. This method receives and returns tokens without any browser redirect.

var signIn = new OktaSignIn(
    baseUrl: 'https://{yourOktaDomain}',
    clientId: '{{clientId of your OIDC app}}'
    redirectUri: '{{redirectUri configured in OIDC app}}'
    useInteractionCodeFlow: true
    authParams: {
      issuer: 'https://{yourOktaDomain}/oauth2/default'
    // other options...

  // Assumes there is an empty element on the page with an id of 'osw-container'
  el: '#osw-container'
}).then(function(tokens) {
  // Store tokens
  // Remove widget
  // Can now render in an authenticated state
}).catch(function(error) {
  // Handle error

Direct authentication

Javascript clients that do not wish to use the Sign-in Widget can use the okta-idx-js (opens new window) and okta-auth-js (opens new window) SDKs to authenticate using the interaction code flow.

// Get PKCE params
const params = await oktaAuth.token.prepareTokenParams();
const { codeVerifier, codeChallenge, codeChallengeMethod } = params;

// API version is required
const version = '1.0.0';

// Start IDX
const idxState = await idx.start({
  // ... other params for IDX
  // PKCE code challenge is needed for call to /interact

// based on the previous idxState.neededToProceed gather the needed data fields
// The needed fields will depend on the policy choices for your org and app
// How you build a UI and gather these fields is up to your application and is not shown here

// As an example, the `identify` step might need `identifier` and `rememberMe` fields
// Once you have those fields, send them to get the next set of remediation options

idxState = await idxState.proceed('identify', {

// If your policies allow for a simple username -> password flow, this might be the next step
// Again, building the UI and gathering the data will depend on the consumer application and is not shown here

idxState = await idxState.proceed('challenge-authenticator', {
  credentials: {

// When idx reaches success state, use the interactionCode to obtain tokens
if (idxState.hasInteractionCode()) {
  const interactionCode = idxState.interactionCode;
  const { tokens } = await oktaAuth.token.exchangeCodeForTokens({

  // Do something with tokens
  const { idToken, accessToken } = tokens;
