Protect PDF with Password: Secure Your Sensitive Data
Email is not secure. If you are sending your Tax Returns, Credit Card Statements, or Medical History as a plain PDF attachment, you are taking a risk. If that email account is hacked, your identity is stolen.
The standard safety procedure is simple: Encrypt the file.
How PDF Encryption Works
When you Password Protect a PDF, the contents of the file are scrambled using mathematical algorithms (usually AES-128 or AES-256).
Without the correct password "key," the file is just gibberish code. Nothing can read it—not Google Drive previews, not hackers, not even the government.

How to Share Safely
Now that you have a locked file:
- Email the PDF to the recipient.
- Send the Password via a different channel (e.g., SMS, WhatsApp, or tell them over the phone).
This "Two-Channel" method ensures that even if a hacker intercepts your email, they still can't open the file because they don't have the password text from your phone.
