Universal Passwordless Links Are Not Working With Redirect
Sep 10, 2025
Overview
Passwordless login links in an iOS app take this format:
https://[our-email-service-tracking-link]
This redirects to URL:
https://[our-tenant-name].auth0.com/ios/com.[our-domain].app/email?code=129123
However, with the redirect, it is not possible to directly open the app from the link. The user must first open the link in a Safari browser.
Universal Links have been enabled in Xcode. However, although the final link does work perfectly, the redirect does not function as we expect.
It is desired that the user should be able to directly open the link, without the need to use a browser.

- Passwordless
Solution
Some people have developed workarounds, as in this Stack Overflow thread. As this is a 3rd party solution, Auth0 cannot guarantee that this will work as expected.
The best/easiest option would be to disable the tracking in the email service if possible for the passwordless links such that the links are sent unchanged.
