This is probably a simple question.
I have InfluxDB and Chronograf running nicely as services on a virtual private server. I now want to password-protect Chronograf so that a username and password are required to view data.
I have looked at https://docs.influxdata.com/chronograf/v1.7/administration/managing-security/#chronograf-security and not having set up anything like this before, I don’t know where to “set the environment variable” (i.e. TOKEN_SECRET = )
Is this in a config file somewhere? Or can someone point me to a newbie-friendly explanation?
