I have recently created an account in mongoLab.When I am trying to connect to the database using the below statement.

var mongoose = require('mongoose');
mongoose.connect('mongodb://mk:[email protected]:47742/mkdb');

I'm always getting the following error

MongoError: auth failed

Make sure you are using the database username and password not the account username and password from Mlab.

In MLab, formerly MongoLab, do the following

  1. Navigate to Users
  2. Add Database User
  3. Choose your username and password

Now you can test this on the shell with mongo ds061374.mlab.com:61374/yourdb -u <dbuser> -p <dbpassword>
