Just solved my own question. Below is the code i used, if you have another suggestion (especially with out using a variable like $hashref) I would like to hear it. 
use warnings;
use strict;
use Data::Dumper;
sub test (\%);

my %Record1 = ( username        => '$' ,
                password        => '$' , 
                emailAddress    => '@' );
my $hashref = \%Record1;

$hashref->{username} = 'NOOoooooo!';

&test( $hashref );
sub test (\%) {
    my $reference = shift;
    my $test = "Pigsy's Perfect Ten";
    $reference->{username} = $test;
    print $reference->{username}, "\n";
}
print $Record1{username}, "\n";
