Forgotten user name

[Linux for blind general discussion]

Hello list,

This is really embarrassing to say because I have been working on installing arch linux for a few days.

Saying that,. I finally got it installed and realized I forgot my root user name. Is there a way a to reset it or find what it is? That is without having to reinstall it?

Any help would be greatly appreciated 
 

Sincerely,

Michael maslo
