It is strongly recommended from a security perspective to use a database user other than the root when installing the web application and services. The following can be used to create the user in Windows in a command prompt.
The ArangoDB web GUI can also be used. It is important to set read/write privileges for the user on the ActifyDB database.
You will need your root password to enter the arangosh shell program.
CODE
cd c:\Program Files\ArangoDB3 3.2.5\usr\bin
arangosh
require("@arangodb/users").save("username","password")
require("@arangodb/users").grantDatabase("username","ActifyDB")
require("@arangodb/users").grantCollection("username", "ActifyDB", "*", "rw")
exit
Note: The c:\Program Files\ArangoDB3 3.2.5\usr\bin directory path is based on the version of Arangodb you've installed. Adjust accordingly.
