+1 This is extremely annoying. There's no reason using Touch ID should force me to re-auth my phone at a higher frequency.
Previously, I had a 4-digit PIN code set to ask for auth every 15 minutes. Now, I've set a much longer unlock password and added Touch ID, which is a big step up in device security.
If users are allowed to be more relaxed about device security using the 4-digit PIN, why can't use my own discretion and allow myself to use a (e.g.,) 15-minute re-auth timeout while using Touch ID?
The only reason I can see this as a valid restriction is if people are using Touch ID for their iTunes password as well. If I turn off Touch ID for iTunes purchases, I would expect to be able to set whatever re-auth timeout I wanted.
