What are common pitfalls when adding authentication to a PHP WebService?

One common pitfall when adding authentication to a PHP WebService is not properly securing sensitive information such as passwords or API keys. To solve this, always hash passwords before storing them and never hardcode API keys in your code. Additionally, ensure that you are using secure protocols like HTTPS to encrypt data transmission. 

// Example of hashing passwords before storing them
$password = 'password123';
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

// Example of securely storing API keys
$api_key = 'your_api_key_here';
// Store API key in a secure environment variable or configuration file

// Example of using HTTPS for secure data transmission
// Make sure your web server is configured to use HTTPS
