Identity PSK provides the simplicity of PSK with the benefits of 802.1X, and is available today in the Meraki dashboard.
Many IoT devices are not compatible with 802.1X, leaving IT admins no choice but to use WPA2 or a pre-shared key for authentication. Unfortunately, both methods come with well-documented security flaws. Identity PSK provides a way to assign users and devices unique keys, build identity-based groups, and scale them across the network.
When a client associates to a Meraki access point, the AP will send the MAC address of the device to the RADIUS server. The RADIUS server is able to respond with the PSK, which then allows the access point to authenticate the device.
