Why password-Protect a Confidential PDF?

Frequently Asked Questions

How strong is the encryption?
The PDF is encrypted with AES, the industry standard. Use a long, unique password for strong protection.
Should I send the password in the same email?
No. Share the password separately — by phone, text, or a different channel — so an intercepted email alone can't open the file.
