Implementing Personal Identity Verification (PIV) card signature from Model Driven App (Webform)

Hello All,


I am trying to find out if there is a way to implement webform signing using PIV card authentication. The scenario is something like this:


Whenever a user opens a Model Driven App, goes to one of the entity's webform and click on a custom sign button, a PIV card authentication prompt should appear where a user is challenged with his PIV card login, once authenticated, we populate a field on the webform with the digital signature.


We have seen options like DocuSign and AdobeSign, however they all need licenses which is a thing of a future for us. 


Appreciate any inputs on how to implement this using SDK.

Hi @ShalabhGupta 

Since you are looking for signature. Can you consider having pen-input in PowerApps

If you are looking something in Model driven App. I request you to also post this idea in

Hi Vikas,


Thanks for your reply. 


I've looked at this approach, however this is just a pen control to type in a signature. This is not something which we are looking for. 


Our requirement is to authenticate a user with PIV challenge on a model-driven webform and then authenticate the user post which we will perform some action on the webform.


The use case is something like this
  1. User opens a model driven app
  2. clicks on a button to sign
  3. Challenge provide to the user to use PIV card and sign-in
  4. We get to know if the the sign-in was successful or not based on the challenge.
  5. Based on the sign-in status, perform custom rules.


Let me know if that makes sense. Looking for innovative ways in which we can achieve this.


Thanks for your assistance.

Has any progress been made in this area of capturing a PIV signature within Power Apps? As a government SharePoint admin, I need to move some of our paper processes into this decade, but due to the stringent government audits we must have secure digital signatures (PIV) within Power Apps.
