Error Message: MongoError: bad auth Authentication failed through URI string

Question

I'm trying to connect to my mongoDB server via the connection string given to me by mongo:

"mongodb+srv://david:password@cluster0-re3gq.mongodb.net/test?retryWrites=true"

In my code I am calling the connection through mongoose like this (obviously putting in my password):

const mongoose = require('mongoose');
const db = 'mongodb+srv://david:<password>@cluster0-re3gq.mongodb.net/test?retryWrites=true'
mongoose
    .connect(db, { 
        useNewUrlParser: true,
        useCreateIndex: true
      })
    .then(() => console.log('MongoDB connected...'))
    .catch(err => console.log(err));

When I run the code I am getting the following error

"MongoError: bad auth Authentication failed."

Any ideas of what that could mean?

I guess it should a dot after cluster0 instead of a dash `"mongodb+srv://david:password@cluster0.re3gq.mongodb.net/test?retryWrites=true"` — YoussefDir, Nov 09 '21 at 13:06

I had the same problem, and in my case, the answer was as simple as removing the angle brackets "<"and ">" around <password>. I had been trying: my_login_id:<my_password>, when it should have been my_login_id:my_password.

I think you're confused with the mongodb account password and user password. You should use user password, not account password. That was the reason of my case.

How can I find out my user password in case I forgot it? – Isaac Michaan Jan 23 '20 at 14:42
I don't think you can, Just change it if you forget. You don't need the user password to change your your password solong as you're logged in with your normal account. I think they don't allow you to see it for security reason – Ecks Dee Jul 10 '20 at 20:16
Also for the main question, In my the user password I entered was just wrong so if the answer given by @Harry didn't help check that the user password you used your code is correct if you're sure you're not using your account password with a user login (not account) – Ecks Dee Jul 10 '20 at 20:18
The password needs to be URL Encoded, if in case there are special characters. e.g. **P@ssw0rd#1** will become **P%40ssw0rd%231** – Lovjith May 27 '21 at 14:38

It happens because your provided password in connection string is wrong and most probably you have mistaken cluster password with your login password, in simple words while connecting with Atlas Cluster we can't use our account password by which we login to the Atlas website. In both case we can reset our cluster password and solve this issue.

To Solve The Issue Follow Below Given Steps

Step 1:- Click Database Access From left Side Navigation of MongoDB Atlas page.

Step 2:- Select your username and and click on the edit button from right side.

Step 3:- Click to change password.

Step 4:- Click update user.

While changing password try to keep password only alphabetical because special characters need encoding.

that's all now you can connect.

My problem was not only using the incorrect password ( I was using the account password instead of the user password ( as greatly showed in this answer ) ) but I was also using the "<" and ">" on the password and database name.

Checklist to follow:

1) Make sure you're using the correct password (the DB user password and not the Mongo account).

2) When entering your password, make sure all special characters are URL encoded (for example: p@ssword should be p%40ssword).

3) If you don't remember your password of your DB user - go to Database Access (if you're using Mongo Atlas) -> select your DB user -> edit -> create a new password -> don't forget update to click on 'Update User'.

(!) Security warning: Do not write the password in plain text inside your code - Follow the suggestions given here.

Are you writing your password in the place of <password>? If your aren't, a good practice is to create a environment variable on your operating system and call it using process.env.[your variable]. Ex:

const password = process.env.YOURPASSWORDVARIABLE
const db = 'mongodb+srv://david:'+password+'@cluster0-re3gq.mongodb.net/test?retryWrites=true'

Better yet, you can also put your whole url connection string inside a env variable:

You will set your environment variable on your operating system. How you will do this will depend of what OS your are using, and you need to search for how you will do this on your OS. But for now, to make your code run, just place your actual password instead of ``. – ardmont Apr 15 '19 at 19:54

There are other ways of creating env variables besides to do it on you OS. I reccomend you to read [this article](https://medium.com/the-node-js-collection/making-your-node-js-work-everywhere-with-environment-variables-2da8cdf6e786). – ardmont Apr 15 '19 at 19:58

Adding to above answers, the issue seemed to revolve around a wrong Database password input for me, because of a distortion of what i read as my current password from the Atlas menu and what MongoDB Atlas really saved as my current password.

There seems to be a "bug" when using the "Copy" button when choosing a new password.

What helped me was the following:

Open Atlas in the web
Go to "Database Access"
Click "Edit" on the Database user
Choose "Password" for authentication method
Click "Edit Password"
Click "Show" in the password field
Click "Autogenerate Secure Password"
DO NOT press "Copy" button to copy, but use manual selection via mouse and copy the text via right-click of your mouse or keyboard command
Click "Update User" below

Then: Go through the list of Database users to make sure that no other Database user has the same password you just newly generated.

Now try your Username/Password combination again using this connection string (leaving out the placeholder characters '$' and '[]':

'mongodb+srv://$[username]:$[password]@$[hostlist]/$[database]?retryWrites=true'

I noticed that when I autogenerated a new password by clicking and then clicking the "Copy" button, that the autogenerated password was reset to the old password. Therefore I assumed the new autogenerated password is correct, but in reality it was my old password, which in addition was the same as for another Database user. I could not comprehend that until I clicked "Show" on the password input field.

Not only the password

Check all the fields it could be the password the user or the database. If you misspelt any of these you will have an authentication error.
Go to the database access on the left pane under security:

And in case change the password using edit button. Let's say your password is: P@sW0rd You can compile the URL using the information contained in the Database Users screen:

client = MongoClient("mongodb+srv://giac:P@sW0rd@cluster0.wjdtk.mongodb.net/testc?retryWrites=true&w=majority")

The other answers did not say that even if you mispell the database name you have a authentication error.

Yes, I was misspelling the DB name :) – Sapinder Singh Feb 25 '21 at 06:34 — Sapinder Singh, Feb 25 '21 at 06:34

This worked for me

    mongoose.connect(

      useUnifiedTopology: true,
    }
  );

Create a ".env" file (you need to install dotenv before this ) in the parent directory(if you choose a custom location, add the following in server.js / app.js).

require('dotenv').config({ path: '/custom/path/to/.env' }) //uses custom location

Otherwise, add this in the server.js / app.js (the one that initiates server).

require('dotenv').config() //uses default location

In the ".env" file, define the user, password and database like this

MONGO_USER=uSerName
MONGO_PASS=p@sSW0rd
MONGO_DATABASE=myDatabase

Just remove the angle brackets from both sides of your password.

Wrong Answer :
const db = 'mongodb+srv://username:<password>@cluster0-re3gq.mongodb.net/test?retryWrites=true'

Correct Answer :
const db = 'mongodb+srv://username:password@cluster0-re3gq.mongodb.net/test?retryWrites=true'

Finally, it worked for me to used that connection string with a lower grade that NodeJs versions(2.2.12 or later) cluster url. And After that make sure you have to whitelist your current IP Address from Atlas MongoDB. It should display like 0.0.0.0/0 (includes your current IP address) in Network Access section in Atlas MongoDB. Connect to cluster NodeJs version 2.2.12 or later

And the main issue was where I am storing that connection string url in a constant that part. So initially,I was storing that connection string value in single/double quote but every time I was getting Authentication failure error as it was unable to parse that "Password" value from Atlas mongoDB . So I used backtick (``)instead of single/double quote to store that connection string.

Sample code where I am connecting mongoDB Atlas through a NodeJs application.

const DB_USER = 'your username in atlas mongodb';

const PASSWORD = encodeURIComponent('your password in atlas mongodb');

const url = `mongodb://${DB_USER}:${PASSWORD}@cluster0-shard-00-00.3ytbz.mongodb.net:27017,cluster0-shard-00-01.3ytbz.mongodb.net:27017,cluster0-shard-00-02.3ytbz.mongodb.net:27017/sample-db?ssl=true&replicaSet=atlas-z26ao5-shard-0&authSource=admin&retryWrites=true&w=majority`;

mongoose.connect(url,
  {
    useNewUrlParser: true,
    useUnifiedTopology: true,
    useCreateIndex: true,
    useFindAndModify: true
  })
  .then(() => {
    console.log('Connected to database !!');
  })
  .catch((err)=>{
    console.log('Connection failed !!'+ err.message);
  });

This gives me the following : { MongoNetworkError: failed to connect to server [cluster0-shard-00-02.1jykx.mongodb.net:27017] on first connect [MongoError: bad auth : Authentication failed.] — cyruslk, Dec 03 '20 at 19:53

I just had this problem knowing that I was using the correct username, password and DBname.

I tried to change the password for the db user to double check, but it still didn't work.

I then instead created a new user, gave the user admin role, set the password etc, and then used that new user and password (same dbname) for the connection and it worked.

I don't know exactly what the issue was, but hoping it can help some of you save some time :)

After spending almost an hour messing with the URI, changing permissions and configurations and whatnot, I found out I was getting this error message because of a VPN connection I had active. After shutting down the VPN I was able to connect.

So if nothing else works for you, there might be something in your system preventing a connection to be successfully established and mongodb is just responding with bad auth
