Subject Re: [PROPOSAL] Remove unauthenticated localhost login
Date Thu, 08 Sep 2016 14:42:35 GMT
I'd expect a lot of folk evaluating Brooklyn for real use-cases to 
install Brooklyn on a server, rather than their laptop owned by their 
employer. Or for them to use Vagrant.

For Vagrant, we can auto-populate it with an initial username:password 
in the file.

And for Brooklyn on a server, I think we should taking security 
seriously so not allow unauthenticated access from any user who does a 
curl command from that server!
