  3. 3. Terminal will respond with the following:

    {"error":"unauthorized","reason":"You are not authorized to access this db."}

Note

We'll add more security to the databases down the road, but this is one of the simplest ways to add security to a database.

If you were to play around with the command line again, you would be restricted by doing anything with the _users database, but you would also notice...
