Security Tokens

The bridge_key is uniquely generated when you click Add New Bridge in the dashboard. This defines the cryptographic claim that limits hardware to your SoLoPrint Workspace.

Rotating a Key

If you suspect someone gained unauthorized access to your Pi and read the configuration file, you should rotate the key:

1. Go to Settings > Bridges & Hardware.
2. Click precisely on the ... menu next to the compromised Bridge.
3. Select Reset Key.
4. Important: Your Bridge will instantly disconnect and go Offline. You must SSH back into your hardware and update the /etc/soloprint/bridge.env file with the newly generated key, then execute sudo systemctl restart soloprint-bridge.

Deleting a Bridge

If you decommission hardware, selecting Delete Bridge from the dashboard instantly revokes the connection. All physical printers tethered to that bridge will also be archived in your statistics.
