To sign a document, you may be asked to first upload a digital signing certificate issued by a recognised certification authority in your applicable jurisdiction(s) to the platform. For the avoidance of doubt, Boardfolio is not a certification authority of digital certificates, and we do not validate the legality and applicability of any signing certificates uploaded to the platform. 


1. Navigate to My Account > My Settings


2. Click on Signing Certificate under Signature Settings


3. Upload a signing certificate in .pfx or .p12 format and add a description, then Save


Some organisations may accept self-signed digital certificates for handling documents. Adobe allows you to create such a certificate for free. For step-by-step guide, please visit https://helpx.adobe.com/acrobat/using/digital-ids.html for reference.
