Expert advice from Security Specialists
Use a mix of uppercase letters, numbers, and special characters. Avoid common words or personal dates.
Use a password manager to store your PDF passwords. Once encrypted, there is NO WAY to recover the file if the password is lost.
Avoid using the same password for all documents. If one is compromised, all your files would be at risk.
