[erlang-questions] Erlang cookies are secure
Fri Jun 10 08:40:00 CEST 2016
One thing here is that a cookie has to be constant across an environment.
It's not easy to rotate it by tackling a few nodes at a time, and you can't define a new username, roll it out, and disable the old one later. As far as I know, it's always transferred in cleartext, and doesn't authenticate who it is being given to.

People are almost always easier to manipulate or catch in error than
systems are to crack through exploitation of technical flaws.
How is this not exactly the same as a password? Or AWS credentials?
Or a secret key? Or any other of a host of similar schemes?
