On Day Two of GitHub Universe 2019, we announced GitHub Security Lab to bring together security researchers, maintainers, and companies across the industry who share our belief that the security of open source is important for everyone.

Software security is a collective problem, a responsibility that involves producers and consumers of code, open source maintainers, security researchers, and security teams. At GitHub, we want to give the community the tools it needs to secure the software we all depend on.

Today we’re announcing a big step in securing the open source supply chain: we’re welcoming Semmle to the GitHub.

The dependency graph is rolling out for all PHP repositories with Composer dependencies. In addition to Composer, GitHub supports package managers for many other programming languages, including Maven, NPM, Yarn, and Nuget.  

The WebAuthn standard for security keys is making authentication as easy as possible. Now you can use security keys for second-factor authentication on GitHub with many more browsers and devices.

Token scanning has reached a new milestone: one billion tokens identified. We’ve also added five new partners—Atlassian, Dropbox, Discord, Proctorio, and Pulumi.

Commit signing is now enabled for all bots by default.

We’re celebrating an exciting milestone with one million Dependabot pull requests merged.

Yarn now supports security alerts for public and private repositories.

It’s more important than ever that every developer becomes a security developer—that they responsibly disclose vulnerabilities and patch vulnerable code quickly. Today, we’re excited to announce several new security features designed to make it easier for developers to secure their code.
