Portal authentication and 802.1X authentication are different at the network side. Portal
authentication is simple but has poor information security. 802.1X authentication is complex
to install and configure but ensures high information security. The two authentication modes
are used based on service types. 802.1X authentication is recommended for scenarios
requiring high security. The combination of portal authentication and 802.1X authentication is
used to meet requirements of different service on the existing networks. The following table
shows the comparisons between portal authentication and 802.1X authentication.
