What are the potential security risks of passing passwords in hidden form fields in PHP?

Passing passwords in hidden form fields in PHP can pose a security risk as they can be easily accessed by malicious users through browser developer tools or by inspecting the page source. To mitigate this risk, passwords should never be stored in hidden form fields. Instead, passwords should be securely hashed before being stored in a database, and only the hashed values should be passed through form submissions. 

// Instead of passing passwords in hidden form fields, securely hash the password before storing it in the database
$password = $_POST['password'];
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

// Store the hashed password in the database
// Example SQL query: INSERT INTO users (username, password) VALUES ('$username', '$hashed_password');
