At present, the best way to install applications without Apple App Store is to use Apple's signature. With Apple's signature, users can directly install the application, and the use effect is exactly the same. There are three main signature methods for Apple: Super Signature, Enterprise Signature and tf Signature. Let's briefly introduce them one by one:

After the application is signed by Apple's enterprise, the download address or QR code is generated through distribution. At this time, the user's Apple mobile phone can install the application for the first time through the download link or QR code, and will be prompted as shown in the following figure to download a description file first.

After that, users need to trust the enterprise certificate in the settings-general-profile and device management, and then follow the installation steps, so that the application can be installed quickly. The advantage of Apple's signature is that when installing the application, you can bypass Apple's App Store and audit and install the application directly on Apple's mobile phone by simply operating the trust certificate.

Apple Super Signature:

Apple Supersignature is the most popular one among Apple signatures at present. The biggest difference between super-signature and enterprise signature is that Apple's super-signature application does not need to actively trust the enterprise certificate in the process of downloading and installing.

Users can directly click on the distribution download link or QR code to install. So super signature is more convenient and faster than enterprise signature. Moreover, the stability of super signature is very high, and generally there will be no cancellation of corporate signature. Therefore, Apple Supersignature is one of the most commonly used distribution methods for developers or operators to test applications internally.
