You must create a database user to access your deployment. For security purposes, Atlas requires clients to authenticate as MongoDB database users to access Data Lakes.
If you already created a MongoDB user and added your IP address in your project's IP access list, you can proceed to Connect to Your Data Lake Using the MongoDB Shell.
Estimated completion time: 2 minutes
To add a database user to your cluster:
In the Create a MongoDB User step of the dialog, enter a Username and a Password for your database user.
You'll use this username and password combination to access data on your cluster.
If your password contains special characters, you will need to encode them. For more information, see Special characters in connection string password.
For information on configuring additional database users on your cluster, see Configure Database Users.
