 - `-m, --mac`: MAC address of the target device (format: XX:XX:XX:XX:XX:XX or XX-XX-XX-XX-XX-XX) **[required]**
-- `-u, --username`: Username for authentication **[required]**
-- `-p, --password`: Password for authentication **[required]**
+- `-u, --username`: Username for authentication **[optional for wake, required for sleep]**

 - `-H, --host`: Target host address (default: 255.255.255.255 for broadcast)
 - `-P, --port`: Target UDP port (default: 9 for wake, 9999 for sleep)

 ## Notes
 
 - The tool sends packets using the UDP protocol.
-- The tool supports authentication using a username and password.
+- Authentication is optional for wake commands but required for sleep commands.
 - The tool supports broadcasting to the target host address.
 - The tool supports specifying the target UDP port.
 - Default ports differ between commands: wake uses port 9, sleep uses port 9999.
