"Something you have, something you know, something you are"

Fingerprints are neither. As several people mentioned in this thread, the only thing I see a fingerprint suitable for is replacing a username.

if your timeframe is eternity, this is valid, but for now, the cost of cloning a fingerprint is high enough that they are an excellent protection for a huge category of interactions.

Agreed, but I personally think it shouldn't be a general public feature, but rather reserved to the initiated. The cost lessen quickly with time (a point made by this article) and people have trouble understanding the limitations of a particular protection.

I think people have even more trouble applying other forms of protection. A fingerprint that is actually used is better than a PIN that is disabled, or worse, written on a card.

Unless you lose your device. The device that is literally covered with your fingerprints. In this case, you don't know your data is safe or not. "Probably". Hopefully you'll have remote wipe enabled.

It may be covered with your fingerprints, but that makes it less likely that any of those are usable.
