Can't put a password on my signature

Have you created a Windows Digital ID?

Digital signature in Acroabt and Reader are always password protected, and always include the full date and time when applied.

Hi there

Hope you are doing well and sorry for the trouble. As described, you want to secure signature using a password, so that it prompt for password when you want to use it.

What is the version of the Adobe Acrobat Pro DC you are using? To check the version go to Help > ABout Acrobat and make sure youhave the latest version installed. Go to Help > Check for Updates and reboot the computer once.

Once you create a new digital signature it asks to secure it with a password so that when you try to use it, it will prompt you to enter the password. As described in the pointer 7 of the help page: https://helpx.adobe.com/acrobat/using/digital-ids.html#create_a_self_signed_digital_id

Also once you sign the PDF with digital/certificate signature you will get the date and time stamped within the signature.

For more information please check the help page: https://helpx.adobe.com/acrobat/using/certificate-based-signatures.html

Please try to create a new digital signature as described  in the above help page and see if that helps.

Let us know if you experience any trouble and need more help
