I just wanted to give everyone a heads up that PyPI will no longer accept passwords that have been published in data breaches.

For background you can take a look at https://github.com/pypa/warehouse/pull/4541.

For high level overview see https://pypi.org/help/#compromised-password.

Finally if you have any trouble, please file an issue at https://github.com/pypa/warehouse/issues/new/choose.
