It’s really simple to create a PIN for your Roku account, just follow these simple steps. Visit my.roku.com and sign into your Roku account. Under PIN Preference, select Update. Finally, click the Create PIN button. Then, make changes to your PIN preferences to restrict your child’s ability to make purchases or add channels onto your Roku device. You can also use it to filter out content on The Roku Channel.
If you have a Roku TV, you’ll be asked to create a 4-digit PIN the first time you visit its Parental Controls settings. Note that your Roku account PIN is not the same thing as your Roku TV PIN.
