What are best practices for implementing Secrets management?

        // Example of using Laravel's built-in secrets management with an .env file
        // Store sensitive information in the .env file
        DB_PASSWORD=your_database_password

        // Accessing it in your application
        $dbPassword = env('DB_PASSWORD');
        // Connect to the database using the retrieved password
        $connection = new PDO("mysql:host=localhost;dbname=your_database", 'username', $dbPassword);
