First of all, let me just state that I'm trying to create an app with an AI, so if that's not allowed in this forum, let me know. I'm not an experienced app developer, far from it, so please excuse my ignorance. I have used PC/Windows machines for decades, so the Apple/Mac stuff is foreign to me. My app development but ran into a snag. We're trying to get the app in Xcode to test run on my iPhone 16 Pro. It works in the simulator but fails on the iPhone. It all boils down to the keychain password that keeps popping up. I have only created four different passwords for Apple/Mac and Keychain won't accept any of them. How do I change the keychain password? I have read articles on it but no luck. Appreciate any help. '24 Mac Mini, M4, Tahoe 26.6.2 Xcode 26.6
