Touch ID with iTunes sync

[jacketinshoe]

What happens when a Touch ID enabled iPhone 5S is connected to PC iTunes for sync / backup? Does one have to:
- authenticate using fingerprint on the phone
- enter passcode on the phone
- enter passcode on the PC

At what stage does the following warning appear: "Trust the currently connected computer? Trusting this computer will allow it to have full access to your device and all of its data."

If it's a trusted computer you won't need to do any security...

Not sure about the print but as soon as I connect my 4S / mini to the PC I get the trust prompt.

I apologize; should have been more precise. The questions were asked in the context of plugging an Touch ID enabled iPhone 5S into a new (untrusted) computer.
