The phone is covered with fingerprints from the owner anyway.

If you have the phone, you already have the "password". The fingerprint scan is just to make it a little bit annoying for attacker, so they'll factory reset instead of bothering to crack it.

It's not intended for any kind of real security.

Like many others here I never used to lock my phone at all until the fingerprint scan, and I don't consider the scan as a form of security, but rather as a quick way to turn on the phone.

This is a ridiculous assertion. On the front, I have an oleophobic screen and constantly wipe the phone (i.e., put in pocket). On the back I have a leather case that would be impossible to get prints from.

Do you know of any demonstration that isn't "lab conditions" where touchID is broken?


How do you know that the finger data the scanner uses is present in oil prints?

If this true, someone would have created a working demonstration in the past 5 years.
