By default all Signed PDF files are sealed with a randomized password so they cannot be modified in any way.
Adobe Sign support can remove the security seal and apply a specific password that you can use to unlock the signed PDF file that is attached to the Signed & Filed emails.
PDF files that are viewed/downloaded from the Manage tab or via the API remain encrypted and cannot be modified in any way.
The document encryption is a back end setting that support can change to a password of your choosing, submit a support ticket with your request, and include the password you would like to apply (letters and numbers only, no special characters).
This setting affects Signed PDF files that are sent from the point the setting is adjusted and forwarded. You cannot use that password to unlock previously signed and sealed PDFs.
Once the unlock password has been applied, you can follow these steps to unlock the PDF file:
- Open the PDF that is attached in the Signed & Filed email.
- Click the 'Lock' icon in the upper-left corner of the page.
- Click the link labeled: 'Permission Details.'
- In the "Security Method' drop down, select: 'No Security.'
- Enter your unlock password and click the OK button three times.
You can now make any edits in the file.
