Recently we have been getting more request from users for "Single Sign On" (SSO) for Zoho services. Single Sign On allows users to register just once to use all Zoho Services.
Recently Priya Ganapathy from RED HERRING finds this annoying to sign up separately for each program ( http://www.redherring.com/article.aspx?a=18050 ). I, being one of the frequent user of Zoho services ( Zoho Writer, Zoho Sheet, Zoho Show, Zoho Planner & Zoho Creator ), I can understand the pain.
We have been working hard to get this out soon. The delay is due to the data migration. We have come close thrice but since we are not fully satisfied with the way we handled existing users, we just decided to change the design.
Having our own Identity Access Manger software ( http://www.securecentral.com/products/iam/index.html ) made it simple for us to support Single Sign On. But handling existing user base with no ( or minimal ) impact is the real challenge we are figuring out to solve. We are happy that most of the features we required were already supported in IAM & this saved lot of time for us.
We apologize for paining you without Single Sign On. We will do our best to get this out real soon.
Stay Tuned !!!!
