PDF password protection FAQ
Does this prevent someone from copying visible content?
An opening password restricts access to the file. It does not prevent a person who can open it from taking screenshots or sharing its contents.
Can I remove the password later?
Use Unlock PDF with the known password to create an unlocked copy. Keep the password available.
