Pre-shared key (PSK) is a simple and widely used authentication method in home and small office wireless networks. All devices connecting to the network use the same pre-shared key (password) for access. While easy to set up, PSK poses security risks if the key is weak or shared with unauthorized users.
Enterprise authentication, also known as 802.1X or WPA-Enterprise, is a more secure and scalable method used in large organizations and business environments. It involves an authentication server (e.g., RADIUS server) for user verification. Clients initiate the authentication process and send credentials to the server for verification. Enterprise authentication supports various EAP methods for stronger and more secure user authentication.
Open authentication is the simplest form of wireless network access control. In an Open network, the access point allows any device to connect without requiring any authentication or encryption. This method offers no security and is generally not recommended for sensitive or private networks. Open networks are commonly used in public places or guest networks where ease of access is prioritized over security.
