Password-protecting a PDF encrypts the file so it can only be opened by someone who knows the password you set. It's the standard way to send sensitive documents - contracts, financial statements, personal records - by email or file-sharing links without worrying about the wrong person opening them if the file is intercepted or shared further than intended.
