What changed

Unity feature: Asset package signatures

Unity checks signatures when importing exported .unitypackage files. The signature identifies the publishing organization and helps detect changes made after export.

Use it

  1. When exporting an asset package, sign in to the Editor and select the organization associated with the package.
  2. When importing, inspect the displayed publisher and signature status before choosing which assets to bring in.

Requirements and limits

  • Signing requires an internet connection. Older Editors can import these packages but do not verify their signatures.
