Hello,
I’m storing some values in the Keychain with the attribute ‘ksecattraccessibleafterfirstunlockthisdeviceonly’ (https://developer.apple.com/documentation/security/ksecattraccessibleafterfirstunlockthisdeviceonly).
When I migrate user data between iPhones via iCloud, this behaves as expected and the keys are not preserved.
However, when I migrate using a direct connection between two devices, the keys are preserved, which seems to contradict the attribute’s intent.
Is this a known behavior, and if so, is there a workaround?
