What is Kerberos SSO?
Kerberos is a computer network authentication protocol, which provides a secure Single Sign On(SSO) based on a trusted third-party mutual authentication service. … It acts as a trusted third party cause all the keys of users and services are managed by the Kerberos server.
Is OpenID an SSO?

Can master key be changed in Kerberos?

What does Ntlm stand for?

Is SAML Kerberos?
Kerberos is a lan (enterprise) technology while SAML is Internet. Kerberos requires that the system that requests the ticket (asks for user identity, in a way )is also in the kerberos domain, SAML does not require systems to sign up before.
Is Kerberos modern authentication?
Kerberos is a ticket-based authentication system for exchanging information. The announcement listed a bunch of other old protocols to block when using Exchange Server 2019, including things like Exchange Active Sync, IMAP and POP3.
