Users who are using a form I create aren't able to add a certified signature whenever I add 'Protect > Secure with Password to the PDF. How can I allow them to add their certified signatures? I have added the fields and specified the type as 'Signature Blocks' to no avail.

Actually, you can Certify after saving with a password. I just tried it with a visible signature in a previously authored signature field. Make sure your protection allows signing with digital signatures.
