Signature Authentication

I received a call from a processor asking for our certificate of signature authentification. Our signatures in Skyslope forms do not have a little box around them showing it is an authentic Skyslope/Digisign-acquired signature, much like dotloop, docusign and other signing platforms have. I do realize, everything can be faked these days but I also recognize that the signatures we acquire with Skyslope/Digisign show nothing to identify them as authentic. Also, if Skyslope and/or Digisign is available to other agents outside of EXP Realty (and I believe it is), it would also serve as a micro advertising tool, making people aware of Skyslope/Digisign who have never heard of it.
