I leave it enabled, then power the phone off before interacting with The Man, like when going through customs. Touch ID is disabled on a fresh boot until you enter your passcode, so that basically turns it off temporarily. This is briefly mentioned in the article.

Another thing you could do is set it up with an unusual finger, like the middle-finger of your non-dominant hand. After five failed tries, Touch ID is disabled until you enter your passcode, so you can use the wrong finger five times when they ask you, and disable it that way. Say you're sweating too much or something (a common cause for real Touch ID failures for me).

It all depends on just how paranoid you are and what you want to defend against.

Having got sick of damp fingers blocking Touch ID I added my nose as one of the options. No more lockout during dish washing.

Are noses sufficiently different from one another that someone else's nose won't be able to unlock your device?

[robotmlg]

Can a US court order compel you to provide your nose print?

[prawn]

Someone needs to be the first to make the news for refusing to do so!

This works? Genius!

I did this so I can unlock my phone with my snowboarding gloves on. I can unlock with the nose and then press the texting app button with my nose to read tests.

Do we know if nose-prints are particularly unique? Or even unique in the context of how fingerprints are typically analysed?

I did this and then tested it against several friends and family. I could only unlock the phone about 75% of the time, but I never got a false positive after about 20 different tries over the next week or two (cleaning the sensor regularly, of course)

I'd guess probably not, but as a 'password' it might be suitably random if you only get 5 attempts.
