**TL;DR:** To run beta apps on iOS, you must trust the Enterprise developer certificate in Settings > General > Device Management.

Since iOS 9, testers are required to _trust_ your organization’s Apple Enterprise developer certificate before running Beta distributions. This is a one-time process.

When running an App from an untrusted certificate, testers will see the message **Untrusted Enterprise Developer**. They can trust the certificate by following the steps below:

**Navigate to Device Management**

Go to **Settings** > **General** > **Device Management** on your iOS device.

**Select the Developer Profile**

Locate and select the developer profile under the **ENTERPRISE APPS** section.

**Trust the Developer**

Tap **Trust "\[Developer Name\]"**.

**Confirm Trust**

Select **Trust** to confirm.

Remember to only trust Enterprise developers that you know and trust.
