Hey, whats the better way to secure phpmyadmin access from external?

Yeah i think we can do the same as Step Two — Secure your phpMyAdmin Instance with CWP at Apache redirect's /index.php?module=system_redirects

But some1 told me if we change that redirects it will mess with some features. any1 can confirm?
If we go to /index.php?module=system_redirects
and change
Redirect permanent /phpmyadmin
and
Redirect permanent /phpMyAdmin

to something else it will work fine or we'll get some problems?

Why should you worry about it? The phpmyadmin itself has a login form !
Anyway, maybe you add another secured layer, example only authorize for a certain IP or certain country to access phpmyadmin URL, otherwise, die();
Tips: search google for htaccess and geo IP, or 'how to check IP using PHP'
