Are there any best practices for handling user authentication with external websites, such as Zwinky, in PHP applications?

When handling user authentication with external websites like Zwinky in PHP applications, it is best to use OAuth or OpenID for secure and standardized authentication. This allows users to log in using their existing credentials from the external website without exposing sensitive information. Implementing OAuth or OpenID ensures a seamless and secure authentication process for users. 

// Example code using OAuth for user authentication with Zwinky
$provider = new League\OAuth2\Client\Provider\GenericProvider([
    'clientId'                => 'your_client_id',
    'clientSecret'            => 'your_client_secret',
    'redirectUri'             => 'https://your-redirect-uri.com/callback',
    'urlAuthorize'            => 'https://zwinky.com/oauth/authorize',
    'urlAccessToken'          => 'https://zwinky.com/oauth/token',
    'urlResourceOwnerDetails' => 'https://zwinky.com/api/user',
]);

// Get authorization URL
$authorizationUrl = $provider->getAuthorizationUrl();

// Redirect user to Zwinky for authentication
header('Location: ' . $authorizationUrl);
