Hi @Tallguy48,
Thanks for reaching out to the Roku Community.
During Guided Setup, you will be prompted to enter an email address to begin the activation process. The email address you need to enter is the email address associated with your Roku existing account. Keep your smartphone or computer handy, as you will need to access your email in order to activate your Roku streaming device.
To learn more, visit our detailed instructions on our support page: How to activate or link your Roku streaming device
Please let us know if there is anything else we can assist you with.
Regards,
Nimfa
