PHP - Simple password protect

Php - Simple password protect 

This is just a reminder page for me.

<?php

$username = $_POST["username"];

$passwort = $_POST["passwort"];

$pass = md5($passwort);

echo $pass;

if($username=="userName" and

#pass = asd

$pass=="7815696ecbf1c96e6894b779456d330e")

   {

   echo "<br>Herzlich Willkommen";

   }

else

   {

   echo "<br>Login Fehlgeschlagen";

   }

?>

<form action="password.php" method="post">
Benutzername:<br>
<input type="Text" name="username"><br><br>

Passwort:<br>
<input type="Password" name="passwort">

<input type="Submit" value="Absenden">
</form>
