How to stop PDFs from being created with passwords

[28853462ymw9]

I've never set a password to encrypt my PDFs and I don't understand why its so difficult to just have a change password button. I just want to place MY PDFs in indesign but I can't without a password. I just want to figure how to make adobe acrobat stop encrypting my PDFs permanently because I don't know the password.

Hi,

How are these PDF files created? Acrobat by default does not place a password on any files. If you could provide more information we may be able to help.
