Hi @mike59,
Greetings from the Roku Community!
We are happy to help you with your query. The 'Pin preference' should be shown under 'My Account' at the bottom, in the middle.
For more details, you can check out this support article on how to create, reset, or remove your Roku PIN.
We hope this helps.
