Authorized websites:
On the Authorized Websites page, you can see a list of websites to which you have granted permission to access your Zoho Account. When you access such websites (Trusted Domains) in the future, you are automatically signed in. This saves you the hassle of re-entering your username and password.
This page also gives you details like the date on which you gave the permission and also the IP address from which the permission was given.If you do not want a website to have access to your account, just click on the “Revoke Access” link.
