Since it's the first Stack Overflow link from "mongodb create db with username and password" query in Google, here's the answer:

use mydb
db.createUser(
   {
     user: "myuser",
     pwd: "mypassword",
     roles: [ "dbOwner" ]
   }
)

These commands will create a database named mydb, assign a user named myuser with password mypassword and grant him full access rights on that db.

Make sure you are admin beforehand, so that you're able to create dbs and users.

[Note] In order to get the newly created database to show in the list returned by command show dbs, you need to insert at least one document into a collection of the newly created database. For example:

> mydoc = { firstName : "Adam" }
> db.mycollection.insert( mydoc  );
