How can developers improve code readability and maintainability when working with password authentication in PHP?

Developers can improve code readability and maintainability when working with password authentication in PHP by using secure hashing algorithms like bcrypt, storing passwords securely in the database, and implementing proper error handling. Additionally, separating authentication logic into separate functions or classes can help organize the code and make it easier to maintain. 

// Example of securely hashing and verifying passwords using bcrypt

// Hashing the password
$hashedPassword = password_hash($password, PASSWORD_BCRYPT);

// Verifying the password
if (password_verify($password, $hashedPassword)) {
    // Password is correct
    // Proceed with authentication
} else {
    // Password is incorrect
    // Handle authentication failure
}
