Question

Quizplus · Accepted Answer

CHAP (Challenge-Handshake Authentication Protocol) does not transmit unencrypted credentials; instead, it uses a challenge-response mechanism for authentication. However, it is considered less secure than some alternatives because it is susceptible to dictionary attacks and other methods that can potentially reveal the credentials. It does not have a limitation to be used only with IKEv2, and it does not inherently allow for the integration of multiple authentication methods in the sign-in process.
