Use Touch ID for Purchases

For free downloads, click Require Password to require a password with each download, or click Save Password to have a saved password used automatically for free downloads. This option is not available when you select “Use Touch ID for Purchases.”
Purchases and In-App Purchases
For purchases and in-app purchases, click Always Require to require a password with each purchase or click “Require after 15 minutes” to not require passwords be entered for purchase made within the same 15-minute interval. To save your password in the app so that you can enter it automatically, click Never Require. This option is not available when you select “Use Touch ID for Purchases.”
