Matter::SessionManager

Inherits Reference < Object

SessionManager manages secure communication sessions

Matter uses two types of sessions:

PASE (Password-Authenticated Session Establishment): Used during commissioning
CASE (Certificate-Authenticated Session Establishment): Used for operational communication

During failsafe rollback, PASE sessions must be cleared to prevent unauthorized access if commissioning fails.
