How to Trust an App on iPhone

Sometimes you just need to take the leap

Apps from the App Store have been vetted and approved. This means the app can be installed on an iPhone using only an Apple password or Face ID. For software that didn't originate from the App Store, manually trust the app to launch it after the installation is complete. This special process is often the case with enterprise apps that are created by an employer for internal use.

Instructions in this article apply to iOS 13 and iPadOS 13 and all currently supported prior versions of iOS.

Trust the app creator as well as its download source. If you're uncertain, avoid trusting the app, as your personal data and iPhone could be compromised.

  1. Download and install the app.

  2. Tap the app icon to open the app.

  3. A message informs you that the app developer is not trusted on the iPhone. Tap Cancel to close the message.

  5. In the iOS Settings, scroll down and tap General.

  6. Scroll down and, depending on the version of iOS, tap Profiles, Profiles & Device Management, or Device Management.

    Can't find the Device Management settings screen? It only shows up if your device is remotely managed by your employer. A normal consumer-grade iPhone or iPad does not offer this screen.

  7. In the Enterprise App section, tap the profile name for the developer of the untrusted app.
