Securing Mail Merge Output PDF Files with Passwords

AutoMailMerge plug-in for Adobe® Acrobat®

Introduction: This tutorial shows how to limit access to output PDF files created during the mail merge process performed by AutoMailMerge plug-in. The document is access can be controled by setting passwords and by restricting certain features, such as copying, printing and editing. The AutoMailMerge™ plug-in provides ability to use either the same password for all output documents or assign an individual password for every file. The software can use text from the data source records to create individual passwords for each output PDF document.; The tutorial also shows how to open a password-protected PDF file and how to remove security restrictions from a PDF document.; A PDF file can have two kinds of passwords: a Document Open Password and a Permissions Password. When you set a Document Open Password (also known as a user password), anyone who tries to open the PDF must type in the password you specify. When you set a Permissions Password (also known as a master password), recipients will need a password to open the document, but they must type the Permissions Password to set or change the restricted PDF features. If the PDF is secured with both types of passwords, it can be opened with either password, but only the Permissions Password allows the user to change the restricted PDF features. Because of the added security, setting both types of passwords is preferable to setting just one.
Prerequisites: You need a copy of the Adobe® Acrobat® along with the AutoMailMerge™ plug-in installed on your computer in order to use this tutorial. You can download trial versions of both the Adobe® Acrobat® and the AutoMailMerge™.
