Touch ID as only for of Iphone unlock?

[Silent UK]

Hi,

I've just got my hands on the IPhone 6 and was wondering why after setting up the Touch ID to be used as my security measure to unlock, it then reverts back to the pin code after 2 failed attempts or if someone swipes to the right?

Is this something I need to get an app for and if so which? Just I don't see the point of having something like a finger print unlock feature and then not to allow it as the only form of phone unlocking? Since pins can be guessed or noted from a distance.

This, I use an 8 digit pin code now instead of 4 in conjunction with the touch ID.

One thing I do find annoying is how often I have to re-enter my Apple ID password though before I can use the touch ID for certain logins.

I'll update the pin to 8 digit in that case.

Was really asking if you could set it to Touch ID only (ie no pin at all)
