The keyfile value points to a file path for a "pre-shared key" that will be used for authentication between the members of your sharded cluster or replica set. This is effectively an internal "password" that can only be used by system processes, not by end users. See Authentication Between MongoDB Instances for more details.

Enabling keyfile also enables auth ( authentication ) for your MongoDB deployment. To set up user accounts you need to:

• Create a user administrator account
• Add user account(s) with appropriate roles
