Need to update the page: https://www.mongodb.com/docs/drivers/node/current/fundamentals/authentication/mechanisms/ Note under MONGODB-AWS that as of 4.11.0 the driver has an optional dependency on @aws-sdk/credential-providers and if it is installed it will be used for getting credentials from the environment. Can also note that: If the optional aws-sdk dependency is installed, the driver will now use the SDK to get credentials from the environment. Because of this, if you have a shared AWS credentials or config file, then those credentials will be used by default if AWS auth environment variables are not set. To override this behavior, set AWS_SHARED_CREDENTIALS_FILE="" in your shell or set the equivalent environment variable value in your script or application. Alternatively, you can create an AWS profile specifically for your MongoDB credentials and set the AWS_PROFILE environment variable to that profile name.
