Users ID consultation / broken

Good morning,

I’m in the middle of Docusign’s validation and I just noticed that the user ID on the signature field cannot be shown entirely in the document nor in the signature certificate (settting the signature to max size doesn’t show it either).

I know that you can check the entire ID of the account users using the Administrator tab but, how about the non-account users? Can I somehow configure the signatures so the entire ID is shown and double checked to ensure that it is actually the same user signing?

I’m specially ‘concerned’ about smartphone signature identity verification because I’m not finding any fields that can be used to reliably identify the user.

Thank you in advance
