Frequently Asked Questions
When should I protect a PDF?
Protect a PDF when it contains information that should not open freely if the file is shared, forwarded, or stored in a wider-access location.
Is password protection enough for highly sensitive documents?
It is a useful layer, but highly sensitive workflows should also follow broader security and policy controls.
How should I share the password?
A good practice is to share the file and password through separate channels rather than sending both in the same message.
