If you received the file from someone else, you need to find out from them what the password is and enter it at the time you try to open the PDF file.
If you created the PDF file, you need to remember the password you applied to that file.
Otherwise, there is no way to open that PDF file. Neither the PDF file format nor Adobe have any secret back door to get around the password. Otherwise, password protection wouldn't be worth anything!
