PDF Password Protection for Email Attachments

Learn how to password protect PDF attachments sent by email in Zanda, how the password is generated, and what happens if a client's date of birth is missing.

Zanda can require a password before a client's PDF attachment can be opened, so a document that reaches the wrong inbox still can't be read.

Turning on PDF password protection

Go to User Menu > Account Settings > Communication > Communication Options and find Enable Password Protection for PDFs. Turn protection on separately for each type of document you send by email:

  • Letters
  • Notes
  • Forms
  • Invoices, Statements, and Superbills (US accounts) or Invoices and Statements (all other regions)

Once a toggle is on, Zanda encrypts every PDF of that document type attached to an outgoing email. This covers emails you send yourself, bulk communications, and automatic or manual reminders. The recipient must enter the password to open the file.

Before you save a newly enabled toggle, Zanda tells you how many client profiles are currently missing a date of birth, so you know who to update first. If you expect that number to be high, it’s worth checking your client list for missing dates of birth before you turn a toggle on, so you can update profiles ahead of time instead of chasing blocked sends afterward.

The Enable Password Protection for PDFs section in Communication Options, showing the four toggles: Letters, Notes, Forms, and Invoices and Statements.

How the password is generated

The password is always the date of birth on file for the client the document is about, not a password you or the client set. Zanda formats it as mmddyyyy for US accounts and ddmmyyyy everywhere else, with no separators. For a shared profile with no date of birth of its own, Zanda uses the primary member’s date of birth instead.

If a client’s profile has no date of birth on file, Zanda can’t generate a password, so it blocks that email rather than sending the document unprotected. You’ll see a message that the send failed because password protection is on and the profile has no date of birth; a failed automatic reminder or automation instead notifies your practice in Practice Hive, naming the client by their client number.

What you see when you send a protected PDF

When you attach a protected PDF to an outgoing email, Zanda shows a message in the email window confirming the attachment is password protected and that the recipient will need to enter the client’s date of birth to open it. If the client has no date of birth on file, Zanda disables the Send button instead and shows a message that a date of birth is required before the email can go out.

What the recipient sees

When the recipient opens a protected PDF, they’re prompted for a password. They enter the client’s date of birth as digits only, with no separators, in the format for their region (for example, 15081990 for 15 August 1990). Once they enter it correctly, the PDF unlocks.
