Robotic Process Automation (RPA)

I just requested an RPA trial. When I opened the link to the "IBM Robotic Process Automation" page, I was asked for a username. I tried several possibilities but the responses were always "Wrong username or password". I didn't see a field for password. What's my username? Is it given in an email?

Hello, the username is your email, the password you must have received an email with the link to create it.
