Hi Alex,
The Morph/Configurator demo site is only intended for demo purposes, so it has its own login:
When you get to the next screen, where you're asked to log in to Configurator, you use the same details.
That said, I see that the Configurator login doesn't work as expected at the moment... I've notified our developers so they will look into it when they're back in the office on Monday. Thanks for notifying us about this. :)
Cheers,
Tess
