How to Trust an App on iPhone?

We all use the Appstore on our iPhones to download the apps that we need. Since Apple does a lot of background security checks before the apps are posted on the AppStore, which means that downloading the apps from AppStore is safe.

The problem comes when you want to install an app on your iPhone from any other place than the App Store. iPhones aren’t designed to let you simply install any apps from any other place, which we see on Android devices.

However, it is not impossible to install an app on the iPhones outside of the app store, but it isn’t an easy process. There is a whole process involved that you need to go through in order to install an app on your iPhone and make your iPhone trust the source and the app.

This restriction is for users’ safety so that users don’t end up installing malware apps or viruses that can cause the iPhones to malfunction.

If you trust the developer of the app, or if it’s an app from your organization that you need to install on your iPhone, then you can try the process of installing an app on your iPhone from a different source other than the App Store.

Manually Trusting an App

On iPhones, we can do the manual process of making the phone trust the source and the app that we are installing on the phone. These apps are known as the Enterprise apps and usually, it is from an educational organization or a corporation’s internal app that they need you to use on your iPhone.

If your organization uses a Mobile Device Management (MDM) solution for distributing the apps to the users to install them on their iPhones. Then trust is automatically established for the enterprise apps on iPhone. However, if you want to manually install an enterprise app, then you’d need to manually trust it to start using it and installing it on your iPhone.

If you try to open an enterprise app that you have installed manually on your iPhone, then you’d see that you can’t open the app and you will get an error that says that it is an untrusted developer.

So, what we need to do is, to trust the developer once, and then you will be able to install the enterprise apps on your iPhone from the same developer.
