What potential pitfalls should be considered when installing phpMyAdmin on a vServer?

One potential pitfall when installing phpMyAdmin on a vServer is leaving the default username and password unchanged, which can make your database vulnerable to attacks. To solve this issue, it's important to change the default credentials to secure your database.

// Change the default username and password for phpMyAdmin
$cfg['Servers'][$i]['user'] = 'new_username';
$cfg['Servers'][$i]['password'] = 'new_password';
