I have a catch 22 just now. So far i have been using Touch ID for both my iPhone & iPad. I like it, its fast & reliable however i now want to change to passcode as i feels the security isnt 100% there for me.
My GF has in the past used my phone when i am asleep by placing the home button to my thumb/finger. Tbf i am a heavy sleeper. She tells me she wanted to listen to some tunes on my phone but i think she got some insecurities right now

as she has woke me asking who certain messages were to etc
Its all innocent on my part and have nothing per-say to hide but it just feels i need another or different layer of protection but am now concerned this will piss her off or feed any insecurity if i suddenly switch to pass code.
I know its not released and details are sketchy right now but does anyone think the iPhone X will allow Face ID to be utilised while the owner is asleep or does it use the eyes for recognition? Lol, i cant beleive im asking but i just kinda get tired of her nagging but if i go passcode i think it will freak her out more
