Captive Portals for Guest Access: These are web pages that intercept users' requests before granting full internet access. They often require agreeing to terms, entering basic information, or viewing ads.
Hospitality Fit: Captive portals are simple to deploy, require minimal user setup, and provide control for the hospitality provider (e.g., usage limits).
Why Other Options Are Less Common:
NTLM: Microsoft authentication, mainly for corporate networks, too complex for casual guest use.
Kerberos: Complex authentication for enterprise, overkill for guest Wi-Fi
SIM Cards: Used in cellular devices, not for general Wi-Fi access.
