Why do I have to "renew Touch ID purchases" all the time?

I have an iPhone 5S, and I have automatic app updates disabled as I like to manage these myself. However, when I do, I have to enter my Apple ID password every time?

If I make new purchases, it seems to go through with the Touch ID; however, if I update an app I am forced to manually enter my password.

I have the 7.0.1 update and apple store purchases under the General => Fingerprint section in Settings, which is turned on.

I have searched the apple discussion forums and the common answer seems to be the update. It's not that.

So short question is, why do I have to actually "Confirm Apple ID password for to renew Touch ID purchases" all the time?

How can I have it use TouchID as I have it set in the settings?


Security, if someone else puts his finger into touch ID, he could purchase everything. Or if someone logs in with his apple id on your phone, you could just buy things without knowing his password.

Touch ID isn't linked to your Apple ID, but to your phone
