Enable Universal Links Support for your Auth0 Application in Xcode

Because universal links establish a verified relationship between domains and applications, both your Auth0 Application settings and your iOS application need to be in sync. To do this, you need to provide Auth0 with the following information:

  • Team ID;
  • Bundle identifier.

Find Your Apple Team ID and Bundle Identifier

To find your Apple Team ID, go to your Apple developer account summary page.

To find your iOS application's Bundle identifier, go to its Xcode project settings page:

Provide Your Apple Team ID and Bundle Identifier to Auth0

You can establish the universal link from the Auth0 side using Applications page of the Management Dashboard.

Select the Application you want to link with your iOS application. You will see the Settings page for the Application.

Scroll to the bottom of the Settings page and click Show Advanced Settings.

Select the Mobile Settings tab and provide the Team ID and the App bundler identifier values for your iOS application.

Click Save Changes when done.

To test this, check whether the universal links apple app site association file is available for your application. Go to your browser and open: https://YOURACCOUNT.auth0.com/apple-app-site-association (replace YOURACCOUNT with your Auth0 account name).

You can test your universal link by navigating to the following URL using your browser:


If the link is successful, you will return the following JSON (formatted for readability):

  "applinks": {
    "apps": [],
    "details": [{
      "appID": "86WQXF56BC.com.auth0.Passwordless-Email",
      "paths": ["/ios/com.auth0.Passwordless-Email/*"]
