There is a different approach for development for Windows 10 devices. A developer license is no longer required for each device that you want to use to develop, install or test your app. You just enable a device once for these tasks from the settings for the device. That's it. No more renewing your developer licenses every 30 or 90 days!
For Windows 10, you choose what tasks you want to enable on the device. This includes any devices: Windows 10 desktops, tablets and phones. You can enable a device for development, or just sideloading.
All Universal Windows Apps are signed to help keep your device secure. To install an app package on a device to test it, you need to trust the package. For that trust to exist, the certificate that is used to sign the app must be installed on the device. (If the certificate has already been installed, then only the package needs to be added to the device.) The settings that you choose will change the level of security of your device.

||Only install apps from the Windows Store.
||Sideloading is installing and then running or testing an app that has not been certified by the Windows store. For example, an app that is internal to your company only. You can install an .appx and any certificate that is needed to run the app with the PowerShell script that is created with the package. Or you can use manual steps to install the certificate and package separately. If you sideload apps, you should still only install apps from trusted sources. When you install a sideloaded app that has not been certified by the Windows store, you are agreeing that you have obtained all rights necessary to sideload these apps and that you are solely responsible for any harm that results from installing and running these apps.
||You can debug your apps on this PC if you choose developer mode. It replaces the Windows 8.1 requirement for a developer license. You can also sideload any apps if you choose developer mode, even ones that you have not developed on the device. You just have to install the .appx with its certificate for sideloading.
