What is PEAP?

Protected Extensible Authentication Protocol (PEAP) is a type of EAP protocol that encapsulates other EAP methods within an encrypted and authenticated TLS tunnel. This provides a secure means of transporting authentication data. It is commonly used in wireless networks (Wi-Fi) to provide secure authentication using credentials like usernames and passwords, often in conjunction with a RADIUS server. PEAP is often favored for its ease of deployment and improved security over older protocols like LEAP.
