So here is where my mind goes. To mfg a decoy of sorts I go down the street and ask a stranger to provide a fingerprint on my phone as the authorized print. I plan on never using it and will always enter the password instead. I could then deny its my device and when the adversary pulls up the fingerprint request on the phone I supply mine it wouldn't work. Therefore its not my device! I then claim of course to not even know what a password is. Realize this is a weak defense, just saying!!!!!
