"graphcool deploy" from inside the Vagrant box (ubuntu/xenial64 server) is expecting a browser. Any alternative way to login?

You can call the

authenticateCustomer

mutation yourself on the system API if you have the appropriate Auth0 secrets (shared cluster) or the master token (graphcool local). You could try capturing the mutation with

DEBUG=*

set during

graphcool deploy

on a machine and use it to curl from your box. If all of this is not an option, you can grab the token from a browser or other machine and put it into

~/.graphcoolrc

(platformToken, if I recall correctly). Does that make sense to you?

Thank you very much @dpetrick for your help, I'm starting to get a more clear picture now.
