Users need to manually trust the profile when installing an enterprise-signed App. App will not run privately, and can only be used after users trust it, so don't worry about being stolen. Just remember, don't install an App of unknown origin, there won't be much problem. Even if you accidentally install it, don't trust its description file. As long as you don't trust the App, you can't install and run it. Choosing a stable corporate signature on a regular platform is the most reliable.

When installing an enterprise-signed application, just open the device management option in the general bar and general page. On Apple's mobile phone device management page, open the enterprise application name according to the prompt, open the name of the application plug-in that needs to be trusted, then click the installed software to verify the trust authorization, then click the trust button, and then open the application software to use.
