Not able to test API REST calls using my email as username

[CommunityUser]

I am on a trial account where my username was set to be my email, but API rest calls documentation states that usernames containing '@' will not authenticate. 

How can I create another user for testing API REST calls, as this trial account does not show the manage users option when logging on the web?

Replace the @-sign with %40

For instance user@domain.com becomes user%40domain.com
