P20 Password Reset Challenge Code

I recently acquired two Wyse P20s to try out in a home lab environment. I have no idea what the administrator passwords on these are but I have read that in order to reset the password I need to get the challenge code from my device and then send it to Wyse tech support. I don't have a support contract with them and when I go to the self service portal to register it asks me to register under an existing company. I am not affiliated with any company. Where do I send the challenge code and will it be possible for me to reset these or am I dead in the water?

Thanks
