You don't need to only worry about your device being compromised, your biometric credentials are being leaked by your mere existence.

Before long, I can imagine someone being able to build facial models capable of fooling recognition systems using only a few source images. Your finger prints are everywhere. Iris would be a bit harder, for now, but potentially possible with an image of high enough resolution.

Fingerprint and iris scanners have been compromised with nothing more than a high resolution image https://www.youtube.com/watch?v=vVivA0eoNGM

Yes, and the next step would be kinect-like 3D scanning and "video magnification" for pulse detection ( http://people.csail.mit.edu/mrub/vidmag/ ), but these too could be compromised with some effort.

That's why these should be used only as a replacement for usernames and not for passwords.

They have long range iris identification. It stands to reason that soon that will also be enough to gather a replica without the target knowing.

In fact my research lab recently received a donation of high power telescopes after being used for testing extremely long range iris identification technology. I'm not sure if the project was scrapped or if they are planning on continuing development.
