It has been a while since I windows introduced login with fingertip. iPhone also uses fingertip for unlocking.<p>While the possibility of using facebook/twitter/google/github login in multiple services decreased the need to create more logins/passwords we still have a huge number of logins.<p>Besides that, the password may easily be guessed/stolen. Even with 2 factor in some services (like github and google), recovery codes exist and can be stolen.<p>And about fingertip? Why is not being implemented? Why can't I login with my fingertip on email, facebook, HN, or whatever? And I don't remind of having read that some big IT player intends to implement it.<p>Is it due to security issues on saving a fingertip to a database? I find it hard to believe that it is impossible to implement some protocol to prevent that...
Most fingerprint readers are not that hard to beat. Also, you can't change your fingertip: If <i>one</i> service/device looses to much details about them or someone obtains your prints, everything is compromised. At least with a password, you can change it and be safe again.
