Security is very necessary for a database to keep the data safe and secure. It provides an authentication so if a client want to make a connection needs to authenticate before executing a command.

Use the "config get command"
You can see that the above property is blank means we don't have any password for this instance. You can change this property and set a password for this instance by executing the following command.
When you set this password then if a client runs the command without authentication, he will get an error "NOAUTH Authentication required.". Hence, the client needs to use AUTH command to authenticate himself.
