Problems with Adobe Sign and digitial signatures

I can't connect my Adobe Sign account to Zoho Docs.  I have Adobe Sign under my Creative Cloud subscription, using my Adobe ID — but there doesn't seem to be an option to log in using my Adobe ID account.  The only option is to log in to Adobe Sign with an email and password, which is not the same as logging in with your Adobe ID account. 

Can somebody help me figure out what I need to do to get this working?  Thanks!
