I've just used Siri to recognise a song and realised it unlocked my phone without asking for a passcode or TouchID. I've tried it a few times and it works each time. Does this happen for anybody else? Using the following steps: 1) Ask Siri what song is playing and allow it to identify 2) Press the Buy button You're then taken into iTunes and the phone is unlocked. I'm a bit concerned but don't have any other iOS devices running to test. I'm using iOS 8.0.1. EDIT: False alarm - it was TouchID recognising the finger and silently unlocking the phone in the background. Pretty good feature actually. Thanks to everybody for checking!
