AWS Cognito Configuration

Configuration Details

AWS Configuration

Before integrating Auth Connect into your Ionic app, you’ll need to get AWS Cognito up and running.

Note: For complete information on configuring AWS Cognito, consult the official documentation which includes tutorials on creating user and identity pools and more.

When creating a User Pool, be sure to add an app client. Additional Auth Connect-related configurations can be found under the App integration and Federation sections.

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: com.company.app) you decided on when configuring the Azure AD app above.

Configure Auth Connect

It's recommended to create an AuthenticationService class that encapsulates AWS Cognito 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 AWS Cognito details in the IonicAuthOptions object:

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

export class AuthenticationService extends IonicAuth {

constructor() {
  const cognitoConfig: IonicAuthOptions = {
    // The auth provider.
    authConfig: 'cognito',
    // 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: 'FILL_IN'
    };

    super(cognitoConfig);
  }
}

Some of these IonicAuthOptions values are unique, and must be set based on your Cognito details:

  • platform: Use “cordova” or “capacitor” accordingly.
  • clientID: Your app’s Client ID, found under [User Pool] -> General Settings -> App clients.
  • clientSecret: Your apps' Client Secret, found under [User Pool] -> General Settings -> App clients.
  • 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: com.company.app://callback. Find this under [User Pool] -> App Integration -> App client settings.
  • logoutUrl: The URI to redirect to after the user has logged out. Example: com.company.app://login?logout=true. Find this under [User Pool] -> App Integration -> App client settings.

The discoveryUrl formula is:

https://cognito-idp.REGION.amazonaws.com/USER-POOL-ID/.well-known.openid-configuration

Where REGION is the hosted AWS region (like "us-east-1) and USER-POOL-ID is the Pool Id (like "us-east-1_vdkald21"), found under [User Pool] -> General Settings.
