Hi @BreeBree,
Thanks for posting in the Roku Community!
We understand that you wanted to set up a pin through your Roku smart home app. As of now, we don't have that kind of feature, but we have two-factor authentication with the Roku smart home app to add an extra layer of security. You can check out this link for more information: How to enable two-factor verification on the Roku Smart Home app
I hope it works for you, and keep us posted on what you find out!
Best regards,
John
