Digital Signature using a PIN


I have a base where I am using a checkmark to show a task is completed. Since there will be multiple people with access to the base, I would like there to be an option where if you check the checkbox you will have to verify using your own pin.

This will create a digital signature with time stamp so I can verify who did what. There are other ways to show that a task is completed and by whom, but none of those are really secure or effective the way I want to use my base.
