TF signature (Trusted Facility Signature, referred to as TF signature) is a technology used for application signing and distribution on iOS devices. It is mainly used to bypass Apple's official app review and distribution restrictions. Through TF signatures, applications can be installed and run directly on iOS devices without going through Apple's App Store review.
The download and installation speed of iosTF signature is fast, and there is no blocking at home and abroad. Testflight puts the application on the shelf and downloads it. You no longer need to click on the trust certificate, you can download and use it directly. TestFlight's new distribution model avoids the trouble of frequent corporate signature drops. The distribution link no longer has to worry about the risk of blocking. It is unlimited in number of times and can be downloaded and used on any Apple device. IPATF signature can avoid the expensive price of super signatures. Users can use it for 90 days after downloading it.
