db.dropUser(username, writeConcern)

Removes the user from the current database.

The db.dropUser() method takes the following arguments:

Parameter	Type	Description
`username`	string	The name of the user to remove from the database.
`writeConcern`	document	Optional. The level of write concern for the removal operation. The `writeConcern` document takes the same fields as the `getLastError` command.

The db.dropUser() method wraps the dropUser command.

Before dropping a user who has the userAdminAnyDatabase role, ensure you have at least another user with user administration privileges.

If run on a replica set, db.dropUser() is executed using "majority" write concern by default.

You must have the dropUser action on a database to drop a user from that database.

The following db.dropUser() operation drops the reportUser1 user on the products database.

use products
db.dropUser("reportUser1", {w: "majority", wtimeout: 5000})
