The key is that rConfig uses MD5 for hashing the password, this makes sense because the field can only take 32 characters. This are the command I use.
[root@localhost rconfig]# mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.

The important thing to remember is that this hash "21232f297a57a5a743894a0e4a801fc3" is equivalent to "admin" which is the original password of rconfig in default install. You can always generate a new hash if you don't want to make it the default by using the following link www.md5hashgenerator.com/index.php Or using the CLI, I am not a CLI fan so I did it the easy way. Hope this help someone, it took me a few hours to figure this out.
