The Passpoint profile on the client device needs to specify the EAP method (either EAP-TTLS or EAP-PEAP) and the credentials (username and password) that the client will use to authenticate.
The profile also contains the identity provider (IDP) information that allows the device to automatically connect to Passpoint-enabled networks.
Steps:
Configure the ANQP (Access Network Query Protocol) settings on the Wi-Fi AP to advertise support for EAP-TTLS or EAP-PEAP.
On the client device, create a Passpoint configuration profile that specifies the username and password for authentication, as well as the EAP type (EAP-TTLS or EAP-PEAP)
