ArangoDB allows to restrict access to databases to certain users. All users of the system database are considered administrators. During installation a default user root is created, which has access to all databases.

You should create a database for your application together with a user that has access rights to this database. See Managing Users.

Use the arangosh to create a new database and user.

arangosh> db._createDatabase("example");
arangosh> var users = require("@arangodb/users");
arangosh>"root@example", "password");
arangosh> users.grantDatabase("root@example", "example");

You can now connect to the new database using the user root@example.

shell> arangosh --server.username "root@example" --server.database example
