How Do I Authorize a Tablet?

If a MachineMetrics tablet loses its authorization (for example, after being inactive for an extended period), it must be re-authorized before operators can access the Operator Dashboard. This is a normal security feature to ensure tablets remain securely tied to your MachineMetrics account.

Step-by-Step Instructions

1. Launch the Progressive Web App (PWA) on the tablet.
   Open the MachineMetrics Operator PWA. If the tablet is not currently authorized, you’ll be prompted before the Operator Dashboard loads.

   • If the tablet has not yet been provisioned, follow the full provisioning instructions here: Provision Your Tablet with MachineMetrics Progressive Web App (PWA)

1. Select “Authorize Device.”
   A 4-character authorization code will appear on the tablet screen with a countdown timer.

2. Open the authorization page on a secondary device.
   On a computer or smartphone, go to the correct URL for your environment:

   • Standard customers: https://app.machinemetrics.com/app/tablet

   • GovCloud customers (U.S. Government Cloud): https://app.machinemetrics-us-gov.com/app/tablet

   Enter the 4-character code displayed on the tablet.

1. Complete the process.

   • If the timer expires, the tablet will automatically generate a new code.

   • After entering the code successfully, the tablet will display an Authorized confirmation and load the Operator Dashboard.

Confirm Success

• The tablet shows an Authorized message.

• The Operator Dashboard loads and the device is ready for use.

Tips & Best Practices

• Power: Keep tablets plugged into a reliable power source (avoid machine USB ports).

• Screen: Ensure the PWA screen stays active — tap inside the app to keep WakeLock enabled.

• Use: Encourage regular operator interaction; long inactivity leads to session expiration.

FAQs

• Q: Why did my tablet lose authorization?
  A: Authorization sessions automatically expire after inactivity. This is expected system behavior.

• Q: Can I avoid reauthorization?
  A: Yes and no. Authorization sessions will eventually expire after long inactivity — that cannot be avoided. But you can reduce how often it happens by keeping the tablet powered, ensuring the screen stays on, and using the app regularly.

• Q: Do I need to reinstall the Progressive Web App (PWA) to reauthorize?
  A: No. Reinstallation is only required after a factory reset. For normal session expiration, just follow these steps.

• Q: What if the tablet was never provisioned or was set up with an older method (such as QR codes)?
  A: In that case, follow the full provisioning instructions here:  Provision Your Tablet with MachineMetrics Progressive Web App (PWA)
