What is the difference between NTLM and Kerberos in Windows Authentication?
NTLM is an older protocol and is generally less secure than Kerberos. It’s used in workgroup environments or where Kerberos isn’t supported. Kerberos is the preferred protocol in Windows domains because it is faster, more secure, and supports mutual authentication.
