• Trimble Identity (also called Trimble ID) provides single sign-on access for Trimble and SketchUp online services as well as to authorize SketchUp Pro subscriptions. You can sign-in to one online service and then browse to another online service without a need to sign in again. Starting in 2018 for Shop and 2019 for Pro, some SketchUp products can also be accessed through the Trimble ID.
