Kerberos
A network authentication protocol that uses tickets and symmetric cryptography to allow secure authentication over insecure networks without transmitting passwords.
Kerberos is a network authentication protocol designed to provide secure authentication over insecure networks. Instead of transmitting passwords, Kerberos uses a ticket-based system: users authenticate once to a Key Distribution Center (KDC), receive a Ticket Granting Ticket (TGT), and then use it to obtain service tickets for specific resources.
Kerberos is the default authentication protocol in Windows Active Directory environments and is widely used in enterprise networks. It provides mutual authentication (both client and server verify each other) and supports single sign-on within a domain.
For teams in Active Directory environments, understanding Kerberos is important for managing authentication infrastructure. Password managers complement Kerberos by securing credentials for non-AD systems and services.
