What is PPSK and how does it work.

PPSK (Private Pre-Shared Key) or MPSK (Multiple Pre-Shared Key) is a Wi-Fi security feature that allows multiple users to connect to the same SSID using unique pre-shared keys. Each user or device gets a unique WPA2 or WPA3 key, enhancing security and network management. Here’s a breakdown of their key features:

1. Individual Security: Each user or device has a unique key, preventing unauthorized access from other users on the same network.

2. Network Segmentation: Traffic is isolated per key, ensuring users cannot snoop on each other's data, akin to having separate SSIDs for each user or apartment.

3. Ease of Management: Administrators can manage multiple keys under a single SSID, simplifying network configuration and reducing SSID clutter.

4. Flexibility: Users can roam within the network property while staying connected to their "home" internet, maintaining the same security and isolation.
