XAMPP phpMyAdmin access

XAMPP is great for a quick set of apache/php/perl/mysql for windows.

But had a strange problem for hours.
The phpMyAdmin gave me an access denied error, even after the password was properly set for localhost.
A possible reason is

localhost

is not treat equivalently to

127.0.0.1

So try one or anther might solve the mystery when all other methods have failed.
