Understand portal types in the portal
Portal type refers to the type of access that will be granted to the portal. The three portal types available in Zoho Creator are: Public, Private, and Restricted.
Public - Any user with the link to the portal can sign up and access it.
Private - Only users invited by the admin of the portal can access it. Users cannot sign up for the portal on their own.
Restricted - The users have to sign up and get approved by an admin in order to access the portal.
The choice of the portal type is decided by the admin depending on the type of the users who may use the portal.
