Shared Client Logins across portals / One portal for all apps

Shared Client Logins across portals / One portal for all apps

I'm new to Zoho and trying to find my way around.

Most, if not all zoho one apps have a portal. Is there any way to achieve either of the following?:

1. The end client has a single username and a single password they can use across all portals e.g. help center for desk, portal for crm. So that if they are a CRM portal user, they don't have to sign up for help center and they don't have to login again.

2. Is there an all-in-one portal where clients can login and view everything attached to their account? Tickets, Invoices, Project Details - Just like WHMCS does.
