Password
At least 6 characters, no accents or emojis. It will be asked for every time the PDF is opened.
AES 256-bit encryption, the strongest available for PDFs. Keep an unprotected copy: a forgotten password cannot be recovered.
How do I password-protect a PDF?
- Choose your PDF.
- Choose a password and confirm it.
- Press “Protect PDF”, then download it.
Before e-mailing a payslip, a tax notice or a bank statement, protect it with a password: even if the message is forwarded by mistake, the document stays unreadable without the password.
TwoDocument uses AES 256-bit encryption, the strongest the PDF format provides. Then share the password by a different channel from the document, for example by text message.
Encryption is carried out on your device: neither your document nor your password is uploaded.
