Require a password for App Store and iTunes purchases
You can require a password for every purchase or require a password every 15 minutes.
You can choose how often you want to enter your password when you buy items (including in-app purchases) from the App Store and iTunes Store:
Always Require — Every time you make a purchase, you'll be asked to enter your password, even if you're signed in with your Apple ID.
Require After 15 Minutes — If you entered your password within the last 15 minutes, you won't be asked to enter your password again.
If you don't want to enter a password when you download free items, follow the steps below and turn off password protection for free items.
Require a password on your iPhone or iPad
Open the Settings app.
Tap your name.
Tap Media & Purchases.
Tap Password Settings, then choose the setting that you want.
If you don't see Password Settings, you have turned on Face ID or Touch ID for App Store and iTunes Purchases. To change this, go back to Settings, tap "Face ID & Passcode" or "Touch ID & Passcode", then turn off Face ID or Touch ID next to iTunes & App Store.
