What does the “Untrusted Corporate Developer” error mean when installing an application on iPhone. Working solutions

iPhone allows you to store applications not only through the App Store, but also directly through your computer or TestFlight.

This method is sometimes used by large companies that want to install their applications on smartphones rather than place them in the App Store. A similar method uses external store applications that are supported through websites.

All of these solutions address one detail – they require a corporate certificate developer. If an app user installs apps like Scarlet and TutuApp from the doorstep of stores, they get the “Untrusted Enterprise Developer” error.

What does “Untrusted Enterprise Developer” mean?

The “Untrusted Enterprise Developer” error appears the first time you open an app that was configured manually rather than through the App Store. For example, if it was downloaded via Scarlet or TutuApp.

When connecting through the App Store, all developers automatically ensure reliability, so there is no such error.

You can hear this message, but in this case you will not be able to open the application. Therefore, access to the developer application must be made secure.

How to fix the “Untrusted Enterprise Developer” error on iPhone

You can remove the “Untrusted Enterprise Developer” error by manually confirming the developer profile in the phone interface.

1. Open Settings → General → Profiles and phone management.

2. In this section under the heading Corporate program you will show the developer’s profile. Click on it

3. Click the button Trust

After this, you can store and open any applications from this developer. If necessary, you can delete a profile in the same menu.

Capable of running on iOS 15, 16, 17 and will likely run on future versions of embedded systems.
