Hello the username and Password for Ampps
localhost/phpmyadmin
User = rootpassword = mysql
I found the password by looking in the MYSQL.config file accessed through the Ampps mysql settings cog. (I had to copy and past it to word )
The user name I got from a previous post on how to reset the password, on this thread.
Ampps should make this info eisier to find or make the login automatic as other servers like XXAMP do.
hope it works for others.
