SKULabs Print & Scale Client - Troubleshooting the "Unauthorized" Error

Fix the "Unauthorized" error when you sign in to the SKULabs Print & Scale client: use the temporary username and password from Settings > Printing.

When you sign in to the SKULabs Print & Scale client, you may see an Unauthorized error. This happens when you sign in with your normal SKULabs email and password, or with an expired temporary password.

Since March 2023, the client only accepts the temporary credentials shown in SKULabs. Your normal SKULabs login no longer works in the client.

How to fix the Unauthorized error

  1. Sign in to SKULabs as a manager or admin and go to Settings > Printing.

  2. Find the Username and Password under "Sign in to the print client with the following credentials."

  3. Click the copy button next to Username and paste it into the client.

  4. Click the copy button next to Password and paste it into the client.

The password is temporary and lasts 8 hours. Copy a fresh one from Settings > Printing each time you sign in to a client. If the password shows "Ask your manager or admin.", your user can't see it; ask a manager or admin to copy it for you.

Still seeing Unauthorized?

Reach out to support in chat or email support@skulabs.com. Include the Username from Settings > Printing and ask us to check your PrintNode account setup.
