How to lock a PDF form after signing it

When projects are complex, with many stakeholders involved, document security and record accuracy is critical. 

Using e-signature tools for reviews, approvals and sign-offs speeds up operations and keeps projects moving. 

But the real key to compliance and security is locking the document or its separate parts, to prevent any subsequent changes after signing. 

Keep your paper trails secure with Fluix.

Step 1. Open a PDF in Adobe Acrobat Pro and choose Forms & Signatures > Prepare Form.

Step 2. Double-click the necessary signature field to open its Properties.

Step 3. In Signed, tick the box Mark as read-only. Select one of the options: All fields, All fields except these, Just these fields.

Step 4. Save changes.

Note. In Fluix, you can protect documents with sensitive data with a password. This way, only users who have a password granted by the admin can access the document and edit it. 

To enable password protection, go to Configuration > Settings > Security and tick the Default PDF password box.
