There are certain apps and games for iOS that are not available in the App Store. For that, you’ll need to sideload the said app or game onto your iPhone or iPad. There’s no surprise if you receive an error saying, “Untrusted Enterprise Developer.” That is because you downloaded the app or game that is not trusted by App Store and to protect you and your device from any kind of malware, iOS displays that error.

It is not always necessary that whatever app or game you download from an external source is a potential threat to you or your device. There are many companies having their corporate app for internal use, and thus, they do not list their app on the App Store. Whatever may be the reason, if you are facing this critical error and trying to get rid of it, then here we have written a guide to fix the issue. Just follow the steps after you have installed the app.

How to trust “Untrusted Enterprise Developer” on iPhone in iOS 10

Earlier in iOS 8, the “Trust” option was mentioned right along with the error message and things were a lot easier. But since iOS 9 releases, that option is hidden for your betterment.

Step #1. Launch the Settings app and head over to General.

Step #2. Now tap on Profile.

Step #3. You’ll see your installed app under “ENTERPRISE APP” section; tap on it.

Step #4. All you have to do now is to tap on the “Trust” button and confirm it again when prompted.

Step #5. You can now return to Home Screen and launch the app without any error.

Thing to note here is that if you don’t see “Trust” button under the app profile, then it is likely that the app certificate has expired. To solve the issue, you’ll have to re-install the app and follow the guide again.
