Password protect a PDF: what it is and when to use it

Adding a password to a PDF is the simplest way to protect sensitive information when you email it or store it in the cloud.

Choose a long, hard-to-guess password and share it through a different channel than the file. There's no way to recover it if you lose it.

Common uses

Send contracts, payslips, or medical documents.
Keep encrypted backup copies.
Share financial information.
Prevent casual access on a shared computer.

Tips for better results

Use a long password that is different from your others.
Send the password through a different channel than the file.
Keep it: it cannot be recovered.
