Firestick Parental Controls Guide
Set up a PIN
Settings > Preferences > Parental Controls > turn on. Set a 5-digit PIN. This PIN will be required to purchase or rent content.
Restrict app purchases
With parental controls on, you will need the PIN to install apps from the Amazon App Store. This prevents accidental purchases.
Block mature content
Parental controls let you set content ratings. Content above your set rating will require the PIN to play.
Lock specific apps
Firestick does not have built-in app locking, but you can use third-party app lockers from the App Store to password-protect specific apps.
Monitor viewing
