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.
