npm install-time security and GAT bypass2fa deprecation

GitHub announced on the **GitHub Changelog** that **npm v12** is now generally available and tagged **latest**. This major release turns on **install-time security defaults** previously announced in **June** and initiates the deprecation of **GAT bypass2fa**.

The release mechanics of **npm v12** enforce **install-time security defaults** out of the box during package installation workflows. Additionally, the update marks the official beginning of the deprecation process for **GAT bypass2fa** within the client software.

Engineers and builders updating to **npm v12** encounter modified security defaults during package execution and installation steps. Teams relying on **GAT bypass2fa** must transition away from legacy authentication pathways due to its ongoing deprecation.

As published on **The GitHub Blog**, establishing **npm v12** under the **latest** release tag shifts baseline security defaults for package management across the **npm** ecosystem. This delivers on the security roadmap **GitHub** outlined earlier in **June**.

Teams should test build pipelines against the newly enabled **install-time security defaults** included in **npm v12**. Organizations must audit existing authentication configurations and watch for upcoming milestone announcements regarding the complete removal of **GAT bypass2fa**.
