This article makes some excellent points about using fingerprints as authentication, but I find it's conclusion of continuing to use passwords a bit suspect. The chances of your fingerprint being compromised are real, but no more real than the chances of your password being compromised (brute force, rainbow tables, weak hashing/no salt).  In my opinion the take away should be use 2 factor auth all the time and I also think fingerprints can be an excellent form of 2 factor auth (I forget my phone/2FA device more than I forget my fingers).
