Device & OS

Scenario
Securing a collaborative PDF document with a password while retaining the ability to modify annotations.
Observed behavior
Adding an open password appears to prevent users from editing comments on mobile devices, or users are unable to access the comments without bypassing the password.
Before you start

Ensure you have the correct open password to unlock the document, and confirm that the PDF was not accidentally flattened, which permanently merges annotations into the page background.

Unlock the PDF and Verify Permission Settings

To edit comments in a secured PDF, users must first enter the open password. You also need to ensure that no additional restriction passwords are blocking comment modifications.

An open password strictly controls who can view the document and cannot be bypassed to edit comments. Once the authorized user inputs the open password, the mobile app should allow editing unless a secondary 'Permission Password' restricts commenting.

1
Open the PDF

Launch your PDF reader or editor on your mobile device and tap the secured PDF file to open it.

2
Enter the Open Password

When prompted, type in the correct open password to unlock the document.

3
Check Commenting Tools

Navigate to the 'Comment' or 'Annotate' tab. If the tools are active, you can begin editing.

4
Verify Editing Permissions

If the tools are grayed out, the document owner may have set a Permission Password restricting edits. Contact the owner to modify the security properties to allow commenting.

Frequently Asked Questions

Can I bypass the open password to edit PDF comments?

No. If a PDF is protected with an open password, it cannot be bypassed. You must enter the correct password to view and interact with any part of the document, including editing comments.

Why are my PDF comments uneditable after adding a password?

This usually happens for two reasons: either a 'Permission Password' was added alongside the open password that explicitly restricts editing and commenting, or the PDF was accidentally 'flattened' during the saving process.

Can I edit comments in a password-protected PDF on my phone?

Yes, as long as you have a capable PDF editor app like WPS Office on your mobile device. Once you unlock the file with the open password, you can edit comments provided the document owner hasn't restricted editing permissions.
