How to Use Modern Authentication in Android and iOS Apps

Last updated April 27, 2023 by Appdome

Modern Authentication is the term Microsoft uses to refer to its implementation of the OAuth 2.0 authorization framework for client/server authentication. Modern Authentication leverages standard authentication libraries to enable applications to support single sign-on (SSO) features like 2FA/MFA and to use access and refresh tokens to validate authentication requests.

This KB article provides step-by-step instructions to add Microsoft Modern Authentication to any Android or iOS app without code or coding.

How to Use Modern Authentication in Android and iOS Apps

Appdome is a no-code mobile app security platform designed to add security features in mobile apps.

Appdome’s no-code mobile app security platform offers mobile developers, DevSec and security professionals a convenient and reliable way to protect Android and iOS apps without coding. When a user clicks “Build My App,” Appdome leverages a microservice architecture filled with 1000s of security plugins, and an adaptive code generation engine that matches the correct required plugins to the development environment, frameworks, and methods in each app.

Using Appdome, there are no development or coding prerequisites to build secured apps. There is no SDK and no library to manually code or implement in the app. The Appdome technology adds the relevant standards, frameworks, stores, and logic to the app automatically, with no manual development work at all.

Likewise, there are no required infrastructure changes and no dependency on SAML, OAuth, OpenID Connect or any other authentication standard inside the app.  Users merely upload mobile apps, select the Mobile Enterprise Authentication by Appdome service and click “Build My App.” The Appdome technology adds Modern Authentication and relevant standards, frameworks and more to the app automatically, with no manual development work at all.

The following diagram illustrates the Single-Sign-On flow for apps that have been integrated with Modern Authentication (OAuth2).

  1. The application sends an unauthorized request to reach a resource like which is protected by a gateway, AD, or the app server itself.
  2. The server protecting the resource responds with 401 or 30X response since the request is not authorized.
  3. Appdome identifies the response from the protected resource and opens an internal Webview within the Built App
  4. The internal Webview navigates to the Hub URL (e.g.
  5. The user can now authenticate using any authentication method the hub URL requires, during the authorization session, the cookies and authorization token are received
  6. The Azure server redirects to the Success URI (e.g. https://successful-authentication-internal-url/portal.html) since the authorization succeeded. Note that the app’s Success URI is configured on Azure should match the configuration during fusion.
  7. Appdome identifies the Success URI redirect and closes the internal Webview, returning the view to the original app.
  8. Now, when the app tries to reach the protected resource, the authorization header or cookies are attached to the outgoing request. The gateway will trust these credentials and the app will reach the protected resource successfully.

Prerequisites for Using Appdome for Modern Authentication

In order to use Appdome’s no code implementation of Microsoft Modern Authentication authentication, you’ll need:

  • Appdome account
  • Mobile App (.ipa for iOS, or .apk or .aab for Android)
  • AD Hub URL
  • Authentication Successful URI on AD
  • Application protected resource URL
  • Signing Credentials (e.g., signing certificates and provisioning profile)

The Easy Steps to Use Modern Authentication in Android and iOS Apps

  1. Upload a Mobile App to Your Account.
    Follow these steps to add a mobile app to your Appdome account.
    If you do not have an Appdome account, click here to create an account.
  2. Go to Build > Authentication.
  3. Enable (toggle On) Authentication Profiles.
  4. From the Choose SSO Schema drop-down list, select Mobile Enterprise Authentication by Appdome.
  5. Add the Protected Resources.
  6. Add the Authentication Portal URL.
  7. Add Redirect URIs, namely: specify one or more URIs to be called upon a successful authentication flow such as an IP redirect URI or a company resource address.
  8. If your deployment uses Open ID, Enable OpenID Authentication.
    • If your deployment requires additional HTTP modifiers to authenticate (optional), upload a file
    • The file should be a text file with each row containing a header to add(with + as the first character) or to remove (with – as the first character). e.g:
      +Connection: Keep-Alive
      “-Content-Encoding: gzi”
    • Enter Client ID
  9. Enable Cross-App ID (optional).  The Cross-App ID allows the Built app to share the authentication state for Single Sign-On.
  10. Click Build My App.

The technology behind Build My App has two major elements – (1) a microservice architecture filled with 1000s of code sets needed for mobile integrations, and (2) an adaptive code generation engine that can recognize the development environment, frameworks and methods in each app and match the app to the relevant code-sets needed to add Modern Authentication to the mobile app in seconds. For example, the technology of Open-ID Connect and Webview authentication, work that ordinarily a developer would need to do.

Congratulations! You now have a mobile app fully integrated with Modern Authentication.
