Configuration Details

Azure Configuration

Before integrating Auth Connect into your Ionic app, you’ll need to get Azure Active Directory (AD) up and running.

Note: For complete information on configuring Azure AD, consult the official B2C documentation which includes tutorials on creating a B2C tenant, registering applications, and more.

Create an Azure AD B2C Tenant

If you don't have one, create a new B2C tenant.

Register an Application

Sign into the Azure Portal then navigate to the Azure AD B2C service page (the easiest way to find it is to search for "b2c", then choose "Azure AD B2C".)

Begin by creating a new Application under Manage -> Applications -> Add.

Azure app configuration settings

Give your app a new name, then toggle Yes for both Web App and Allow implicit flow. For Reply URL, specify http://localhost:8100/ along with the name of your app's core login page (typically, login).

Next, toggle Yes for Native client. Note the Redirect URIs that are displayed.

Next, choose your globally unique App Id, which is used both in the Azure configuration as well as Cordova/Capacitor. Typically, this takes the form of company-AppName or reverse DNS style -

With that in hand, set the Custom Redirect URI. After the app user signs into Azure AD, this tells Auth Connect which page to redirect to in your app. Use the formula “uniqueId://page”, such as

After filling in all details above, click the Create button.

Create User Flows (Policies)

Create at least one User Flow, the series of pages that define the entire authentication experience for your app. At a minimum, create a Sign up and sign in flow. Once the User Flow has been created, select it from the User Flow list, then click "Run user flow" from the Overview tab. Note the URL at the top of the page, used to configure Auth Connect's Discovery URL property. Also consider creating a Password reset flow (detailed below).

Azure AD B2C is now ready to use with Auth Connect.

Install Auth Connect

Run the following command to install the Auth Connect plugin. For the AUTH_URL_SCHEME variable, use the globally unique App Id (ex: you decided on when configuring the Azure AD app above.

If using Cordova, run:

ionic cordova plugin add @ionic-enterprise/auth --variable

If using Capacitor, run:

npm install @ionic-enterprise/auth --variable npx cap sync

Configure Auth Connect

It's recommended to create an AuthenticationService class that encapsulates Azure AD and Ionic Auth Connect’s login functionality.

Generate this class using the ionic generate command:

ionic generate service services/authentication

Extend the IonicAuth class, then configure all Azure AD details in the IonicAuthOptions object:

import { IonicAuth, IonicAuthOptions } from '@ionic-enterprise/auth';

export class AuthenticationService extends IonicAuth {

constructor() {
    const azureConfig: IonicAuthOptions = {
        // The auth provider.
        authConfig: 'azure',
        // The platform which the app is running on
        platform: 'cordova',
        // client or application id for provider
        clientID: 'FILL_IN',
        // the discovery url for the provider
        // OpenID configuration
        discoveryUrl: 'FILL_IN',
        // the URI to redirect to after log in
        redirectUri: 'FILL_IN',
        // requested scopes from provider
        scope: 'FILL_IN',
        // the audience, if applicable
        audience: 'FILL_IN',
        // the URL to redirect to after log out
        logoutUrl: 'FILL_IN',
        // The type of iOS webview to use. 'shared' will use a webview that can
        // share session/cookies on iOS to provide SSO across multiple apps but
        // will cause a prompt for the user which asks them to confirm they want
        // to share site data with the app. 'private' uses a webview which will
        // not prompt the user but will not be able to share session/cookie data
        // either for true SSO across multiple apps.
        iosWebView: 'private',
        // required if running on the Web
        clientSecret: ''


Some of these IonicAuthOptions values are unique, and must be set based on your Azure AD app’s details:

  • platform: Use “cordova” or “capacitor” accordingly.
  • clientID: Your app’s Application ID. Example: cebbb0be-d578-4bbd-9712-4b0fe05c06aa
  • redirectUri: The URI to redirect to after the user has logged in. Use the same AUTH_URL_SCHEME variable value (App Id) from when the Auth Connect plugin was installed. Example:
  • logoutUrl: The URI to redirect to after the user has logged out. Example:
  • audience: Your custom API URL of choice, such as
  • scope: Unlock access to protected resources, such as read/write permissions. offline_access is minimally required. Example: openid offline_access email picture profile

The discoveryUrl can be found by navigating to User flows (policies) -> [Select User Flow] -> Overview tab -> Run user flow button. The discovery link is at the top page and will look like the following format:

Where B2C-TENANT-NAME is your tenant name and the POLICY-NAME is the name of the User Flow created earlier.

Check out the full list of configuration options available, then implement the other steps in the Auth Connect workflow.

Implementing Password Reset

To implement password reset functionality, a custom User Flow needs to be created. Navigate to the User flows (policies) page, then click the "New user flow" button. Next, select the "Password reset" user flow type. As part of the Application claims section, choose "Email Addresses" at a minimum. After the user flow has been created, select it from the User Flow list, then click "Run user flow" from the Overview tab. Note the URL at the top of the page - use it as the discovery url for password reset.

Within your app, implement the following logic:

If an error is thrown after the Login function is called, inspect the message property. If it starts with the string AADB2C90118 (part of the error message returned by Azure AD), then call Login again, this time specifying the location of the password reset endpoint.

// Snippet example: Password reset
async login() {
    try {
        await super.login();
    catch (error) {
        // Handle password reset (only applicable for Azure AD B2C)
        const message: string = error.message;
        if (message && message.startsWith('AADB2C90118')) {
            await super.login("DISCOVERY_URL_FOR_PASSWORD_RESET");
        } else {
            throw new Error(error.error);
