Letting Google and Yahoo in the DoorZoho has created a unified login for users who have Google and Yahoo accounts. This capability is due to the single sign functionality Zoho has built around it's applications. The decision to open the doors was partly due to a LifeHacker Poll that asked people what they preferred, Google Apps or Zoho Apps. The results showed that many people chose Google not because they thought it was better than Zoho, but because they were too lazy to create another user account.
So what does Zoho do with this information? They offer Google users the chance to try out their applications without having to create a new username password combo. The same goes for Yahoo users. It's important to note that Zoho does not store your Google/Yahoo password, only your email address.
“In several polls and reviews, we noticed that users prefer our applications to online alternatives,” said Raju Vegesna, Zoho evangelist. “For Google and Yahoo! users who are curious about Zoho but don’t want to set up another account, we’ve removed that hurdle. Users don’t have to create a Zoho account to use Zoho applications. We want to make it as easy as possible for everyone to try our online apps.”You can, at any time, disconnect these ids from your Zoho account.
