How to do user authentication in MongoDB, Prevent others to access MongoDB ?

Big Data, Cloud Security, Cloud Technology, MongoDB, News, Tech Blog, Tech Trends

MongoDB, a cross-platform document-oriented database. Classified as a NoSQL database, MongoDB eschews the traditional table-based relational database structure in favor of JSON-like documents with dynamic schemas (MongoDB calls the format BSON), making the integration of data in certain types of applications easier and faster.

Here I am going to explain how to apply user-name and password(authenticate) to mongoDB’s database.

#1. Open shell command. Fire this command

command – mongo
MongoDB shell version: 3.0.4
connecting to: test


command – show dbs;
admin 0.078GB
local 0.078GB
auth_db 0.078GB


command – use auth_db;
switched to auth_db

Here, we have selected auth_db Database for apply authentication.

#4. Fire query :

db.createUser({user:”YOUR_USERNAME”, pwd:”YOUR_PWD”,roles:[“readWrite”,”dbAdmin”]})

We have created User of database ‘auth_db’. You can set your user-name and password to above query.

Make sure authentication is true. You can set authentication = true in MongoDB.conf file.

  • Option 1: In mongod.conf, Remove comment and make it true.

    – restart mongoDB – sudo service mongod restart

  • Option 2 : command to run mongodb with auth true :- mongod -auth

#5. In database config files in Nodejs

var mongoose = require('mongoose');
var uri = 'mongodb://localhost:27017/auth_db';
var options = {
pass: 'YOUR_PWD'
mongoose.connect(uri, options, function(err, result){
console.log('err -->' + JSON.stringify(err));

Without user-name and password, would not able to perform an operation with the database. If you don’t want to use authentication to database just make auth=true is commented in MongoDB.conf file or start mongo without -auth i.e mongo . Please do not forget restart MongoDB.

You can drop a comment for any questions or feedback. We Will get back to you soon.
