Welcome to the Roku Community, @dramaboy!
Thanks for asking this question! We understand you're unable to access the code within 30 minutes and that you would like to access the validity of the code longer than the default time.
Currently, there are still no options to extend the validity of the code for more than 30 minutes, as this is a system-generated code by default that will expire 30 minutes after being sent to your email.
The best thing that you can do is to have a spare mobile phone or computer on which you can temporarily log in to your email address so that you can get the code before it expires.
This is a good suggestion, though, and we'd pass this along to the team as feedback and feature requests.
Thanks for raising this inquiry with us. Please let us know if you have further clarifications!
Best,
Emman
