I have recently enabled two step authentication on both my iCloud and iTunes store Apple IDs. I have had the same problem two days in a row. When purchasing something, I should be able to use Touch ID. Instead, im prompted to enter my password twice, and also an SMS authentication number. This leads me to believe my devices aren't "trusted." How can I address this? I'm not sure if this matters, but I believe my devices are trusted through my iCloud ID. Can devices be trusted by two separate Apple IDs? Any help, please!
