## Enterprise Signing

If you want to test an iOS App with a enterprise certificate you have to "trust" your organization’s Apple Enterprise developer certificate, to complete the installation.

Your Testers will see the message **“Untrusted Enterprise Developer”** when running an app from an untrusted certificate and can trust it by following the steps outlined below on their device.

2. Select the developer certificate in the **"ENTERPRISE APPS"** section.
3. Press **"Trust \[Developer]"**.
4. Select **"Trust"**.
