The payment method linked to your Roku account allows you to purchase subscriptions to channels, rent or buy movies and TV shows, or make other purchases from the Roku Channel Store. However, you can create a PIN (Personal Identification Number) to prevent unauthorized users in your home from adding channels from the Roku Channel Store, and making purchases with your Roku account. Once a PIN has been created, it must be entered to authorize any transaction with the Roku Channel Store.
Does my Roku account PIN protect against unauthorized purchases on all channels?
No. Once you create a PIN for your Roku account, only purchases made from the Roku Channel Store or from channels that are billed to your Roku account are protected. Purchases made from channels that bill you directly (e.g., VUDU, Amazon Video) are not protected by your Roku account PIN.
However, many of these channels offer a way independent of your Roku account PIN to protect you from unauthorized purchases. If you need more help after following the link below, contact the channel provider directly.
