采用明文的形式存儲密碼會危及系統安全。
當密碼以明文形式存儲在應用程序的屬性文件或其他配置文件中時，會發生 password management 漏洞。
示例：以下代碼可以從屬性文件中讀取密碼，并使用該密碼連接到數據庫。
...
$props = file('config.properties', FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
$password = $props[0];
$link = mysql_connect($url, $usr, $password);
if (!$link) {
die('Could not connect:' . mysql_error());
}
...
password 中的值。而這給了心懷不軌的雇員利用這一信息破壞系統的機會。
