Mongodb – How to secure MongoDB with username and password


I want to set up user name & password authentication for my MongoDB instance, so that any remote access will ask for the user name & password. I tried the tutorial from the MongoDB site and did following:

use admin
db.addUser('theadmin', '12345');

After that, I exited and ran mongo again. And I don't need password to access it. Even if I connect to the database remotely, I am not prompted for user name & password.

UPDATE Here is the solution I ended up using

1) At the mongo command line, set the administrator:

    use admin;

2) Shutdown the server and exit


3) Restart mongod with --auth

  $ sudo ./mongodb/bin/mongod --auth --dbpath /mnt/db/

4) Run mongo again in 2 ways:

   i) run mongo first then login:

        $ ./mongodb/bin/mongo localhost:27017
        use admin

  ii) run & login to mongo in command line.

        $ ./mongodb/bin/mongo localhost:27017/admin -u admin -p 123456

The username & password will work the same way for mongodump and mongoexport.

Best Solution

You need to start mongod with the --auth option after setting up the user.

From the MongoDB Site:

Run the database (mongod process) with the --auth option to enable security. You must either have added a user to the admin db before starting the server with --auth, or add the first user from the localhost interface.
