Hello Bradley
Firstly, welcome to the SBB Community.
If you are asked to verify your identity, you obviously have followed the wrong link and are about to register as a resident.
If you want to register for an SBB account, you have to choose ‘No customer number’ as ‘SwissPass’ is a product for residents, and you do not have a customer number as a tourist.
Use this link
https://sbb-tickets.cc/de/angebote/swisspass-karte/register/1?lang=en
choose ‘No customer number’ .
Kind regards,
Roland
