Kids theses days hate using technology that's older than themselves? Kerberos is amazing and it make me sad to see all these people reinventing stuff that was solved 30 years ago. The number of companies selling SSO and doing it poorly (see this weeks okta hack) is unfortunate.
21yo here, I think Kerberos is bloody awesome, but then I was introduced to it by a somewhat old timer, who showed me its benefits when properly integrated in the company.
