Upgrade your legacy ProContractor sign-in to Trimble ID

You only need to set up a Trimble ID once, and then you can use it to sign in to ProContractor.

  • You must have access to your email to complete the upgrade because the upgrade process sends an email with a validation code which you must retrieve and use.
  • For additional information, see Legacy login to Trimble ID FAQ.
  1. In the sign-in screen, enter your ProContractor username and password and then select Login with Trimble ID.
    ProContractor validates your credentials and then the Trimble Sign In page appears.
  2. For steps to set up your Trimble ID, see Create a Trimble ID.
Upon completing the steps, your Trimble ID and your ProContractor account are now linked. Your legacy/classic credentials no longer work for signing in to ProContractor.
For all subsequent logins, use the Login with Trimble ID button without entering anything in the ProContractor Sign In page.
