Using PyMongo with MongoDB Atlas

Connections to Atlas require TLS/SSL. For connections using TLS/SSL, PyMongo may require third party dependencies as determined by your version of Python. With PyMongo 3.3+, you can install PyMongo 3.3+ and any TLS/SSL-related dependencies using the following pip command:

Starting with PyMongo 3.11 this installs PyOpenSSL, and service_identity for users of Python versions older than 2.7.9. PyOpenSSL supports SNI for these old Python versions, allowing applictions to connect to Altas free and shared tier instances.

Earlier versions of PyMongo require you to manually install the dependencies. For a list of TLS/SSL-related dependencies, see .

Note

You should see “True”.

Warning

Industry best practices recommend, and some regulations require, the use of TLS 1.1 or newer. Though no application changes are required for PyMongo to make use of the newest protocols, some operating systems or versions may not provide an OpenSSL version new enough to support them.

Users of macOS older than 10.13 (High Sierra) will need to install Python from python.org, , macports, or another similar source.

If the version number is less than 1.0.1 support for TLS 1.1 or newer is not available. Contact your operating system vendor for a solution or upgrade to a newer distribution.

You can check your Python interpreter by installing the module and executing the following command:

You should see “TLS 1.X” where X is >= 1.
