Starting January 1, 2024, all users must enable 2FA for their PyPI accounts.
PyPI has been on the path of being a fully Two-factor Authenticated service a reality, which began in 2019. Read more about some of the steps taken in recent months:
Starting today, all users must enable 2FA before they can perform any management actions on TestPyPI.
This change is in preparation for the scheduled enforcement of 2FA on PyPI at the end of 2023.
A PyPI user's account was taken over and used to remove the user's ownership of 4 projects. This was not a malfunction of PyPI or using any vulnerability, rather the user's account was not sufficiently protected against account takeover.
The attacker added themselves as a collaborator to these projects, and removed the original owner. None of the projects had any modifications made to them other than ownership changes.

This post is a deeper dive into the remediation of the security audit findings for cabotage - the codebase that deploys PyPI and its supporting services such as conveyor, camo, and inspector.

We are proud to announce that PyPI has completed its first ever external security audit. This work was funded in partnership with the Open Technology Fund (OTF), a previous supporter of security-related improvements to PyPI.
The current PyPI security reporting procedure
directs reporters to send an email to security@pypi.org with details.
security@ was previously an email alias for admin@,
a Google Group that contains all current PyPI Administrators (4 people).
Back in 2019 we kicked off efforts to integrate with GitHub secret scanning. Due to the complexity in nature, the completed integration launched in 2021, with the volunteer-led effort by Joachim Jablon (@ewjoachim) and the GitHub team.
Starting today, newly registered users must enable 2FA before they can perform any management actions on PyPI. This change comes after we've also added a rule for accounts to have a verified, primary email address for the same set of management actions.
As a reminder, PyPI has supported adding 2FA since 2019.
