For those scared about the login. Normally they dont save that data, it only uses it to verify to apple. Every apple id can be used as a “dev” account for testing of their own apps. Im assuming they made the app in a way that connects to that so you can install other apps. It also resets every week, thats probably why altstore needs a refresh every week to resign the apps
im hoping this works because im on the step of actually getting altserver to see my custom ipa so ill update if it works ((I literally have the ipa, and i can press sideload ipa but it isnt there so ill update if it works)) edit it says "remove all access" but i cant read it all, ill try to screenshot what it says and edit it again
