What is the primary purpose of a portal in Appian?

The primary purpose of a portal in Appian is to connect users without an Appian login to apps. This allows organizations to extend their applications to external users, such as customers or partners, who may not have full access to Appian but need to interact with specific functionalities provided by the applications.

Portals serve as a bridge for these external users, enabling them to access certain features, data, or workflows without requiring them to go through the standard Appian authentication process. This capability is particularly useful for organizations that want to provide streamlined access to services while maintaining security and access controls.

The other options focus on various functionalities related to managing workflows, creating login pages, or connecting authenticated users, which are important in the context of Appian but do not encapsulate the core function of a portal as effectively as facilitating access for non-logged-in users.
