Unified customer portal login

As I'm a Zoho One subscriber I can provide my customers with portal access to many of the Zoho apps. However, the customer must have a separate login for each app, which may be difficult for them to manage and frustrating as all they understand is that they are signing up multiple times to one business.

For example if I have them setup in Desk, Projects, Books and CRM they can login to these but they require a separate username and password for each one.

I would love to see white label, unified login for my clients so they sign up once and then I can manage their portal access all in one place.

Another example is, my customers are signing up to courses I have on TrainerCentral and I want them to also have access to my Zoho Desk Support Portal.

Regards,

Ashley
