Official description
GitHub Workflow Updater is a VS Code extension that automatically pins GitHub Actions to specific commits for enhanced security. Before 0.0.7, any provided Github token would be stored in plaintext in the editor configuration as json on disk, rather than through the more secure "securestorage" api.
