Frequently asked questions
What if I forget the password?
There is no backdoor. Keep an unprotected archival copy in a secure vault if policy allows.
Owner vs user password?
Tools vary. This flow focuses on opening restrictions you configure — test with Unlock PDF on a copy you control.
Is this military-grade DRM?
PDF passwords raise the bar; they are not a substitute for enterprise DRM or access control systems.
Email the password in the same thread?
Avoid it. Send the file and passphrase through separate channels.
Can recipients still screenshot?
Yes. Passwords stop casual opening, not determined screen capture.
