Overview

MongoDB supports multiple mechanisms that you can use to authenticate your application. This page contains code examples that show each of these mechanisms.

Tip

To learn more about any of the authentication mechanisms on this page, see the Authentication Mechanisms and Enterprise Authentication Mechanisms pages.

To use an authentication example from this page, copy the code example into the sample application or your own application. Be sure to replace all placeholders in the code examples, such as <hostname>, with the relevant values for your MongoDB deployment.

Sample Application

You can use the following sample application to test the code examples on this page. To use the sample application, perform the following steps:

  1. Ensure you have PyMongo installed.

  2. Copy the following code and paste it into a new .py file.

  3. Copy a code example from this page and paste it on the specified lines in the file.

4    # start example code here

                             authSource="<authentication database>",
                             authMechanism="SCRAM-SHA-256")
