Your office wants to set up a Wi-Fi network for visitors.

A FortiGate interface can operate with different types of captive portal modes.

The available portal types that require user interaction or login include:

✔A. Terms Acknowledgment Without Authentication

Forces users to accept terms before accessing the network

No credentials required

Still considered a captive portalCommon in guest Wi-Fi.

✔E. Authentication

Requires username/password

Supports local users, RADIUS, LDAP, OAuth, etc.

Why the other options are incorrect

❌B. Email Notification Only

Not a valid captive portal mode on FortiGate.

❌C. Disclaimer + Authentication

This is not a selectable mode; disclaimers are part of the captive portal customization but not a standalone option.

❌D. Guest Pass Access

Guest pass authentication exists onFortiAuthenticator, not as a direct portal type on FortiGate.
