SSO in DocuSign allows specific accounts to be set up for log in with Password (No SSO) or Both. Hence in DocuSign, I was able to set up the Administrator accounts to login with Both methods and User accounts with SSO only.
This is very useful if SSO stops working due to any reason, since it will allow an Administrator to log in to troubleshoot/turn off/recreate SSO.
Please consider this request for the development roadmap and I'll be happy to assist further if needed.
Kind regards,
Pradeep
