Amazon Prime Video offers parental controls, letting you set age restrictions on videos. You can bypass these age restrictions with a PIN. You can even apply the age restrictions only to specific devices, like the ones your kids use.

To set parental controls for your Amazon Prime Video account, head to the Prime Video Parental Controls page. If you aren't already signed in with your Amazon account, you must sign in to continue.

You can also find this page by visiting Amazon.com in your web browser, pointing to "Account & Lists" at the top right corner of the page, and then selecting "Your Prime Video." Click the "Settings" link at the top right corner of the Prime Video page, and then switch to the "Parental Controls" tab.

This page lets you configure Prime Video parental controls. At the top of the page, you can click the "Change" button next to Prime Video PIN to set a five-digit PIN for Prime Video. This PIN will be required to authorize the purchase and rental of prime videos, as well as to bypass any parental controls you set here.

Note: These parental controls apply to most devices. However, Amazon notes that you must set parental controls for Amazon Fire TV devices, Fire tablets, the Fire phone, Xbox 360, and Xbox One devices using the built-in options on those specific devices.

Under "PIN on Purchase," select "On" to prevent people from spending any money on Prime Video without your permission. You'll have to enter the PIN every time someone rents or buys something on your account.

For example, this would prevent children or guests from buying or renting videos in the Amazon Prime app on your TV.

You can also select "Off" and you won't have to enter a PIN whenever you purchase something. This is useful if you're the only one who uses your account, for example.

Select an appropriate age under the "Viewing Restrictions" section. The default is age 18 (Mature), which lets anyone with your account watch all videos on Amazon Prime without entering your PIN. You can also select age 13 (Teen), 7 (Family), or G (General).

For example, if you select age 7, anyone will be able to watch either G or age 7 rated videos, but will need your PIN to watch age 13 or 18 rated videos.

These restrictions are based on the age ratings associated with videos on Amazon Prime Video. There's no way to block or allow individual videos within these age brackets.

Choose the devices to which you want to apply these parental controls under the "Apply Viewing Restrictions To" section. All your connected devices are checked by default, but you can uncheck specific devices if you don't want to be bothered by your PIN on them.

For example, you might want to apply the viewing restrictions to devices connected to your TV and tablets your children use, but not to your own personal iPad that only you use.

Note that anyone with access to your web browser can visit this page to disable the restrictions or change your PIN, assuming you stay signed into your Amazon account.

You might also want to set up an Amazon Household, which lets you add up to four separate "teen accounts" for teens in your household. You can also create additional child accounts that can be used with the child-friendly Amazon FreeTime service.
