What are the potential security risks of passing username and password through the URL in PHP?

Passing username and password through the URL in PHP can expose sensitive information to potential attackers, as URLs are often logged in various places like browser history, server logs, and network traffic. This can lead to unauthorized access to user accounts and compromise the security of the application. To mitigate this risk, it is recommended to use secure methods like POST requests with HTTPS to transmit sensitive information. 

// Instead of passing username and password through the URL, use a POST request with HTTPS for secure transmission

<form action="login.php" method="post">
    <input type="text" name="username" placeholder="Username">
    <input type="password" name="password" placeholder="Password">
    <button type="submit">Login</button>
</form>
