In Riskcast, the username and the user's primary email address do not have to match. 

As long as the primary email is a valid email address, the username can be anything administrators choose to use. For example, John Smith could have j[email protected] as his primary email address and [email protected] as his username.

The Gmail account is where all his Riskcast notifications and emails would go.

Although his Acme email address isn't real, it can still be used as the user's login information.
