Link Signal to Franz

Signal uses its own linked-device flow. Franz shows a QR code, and your phone authorizes Franz as a linked desktop device. Keep your phone online and open Signal on the phone while completing the link.

On your phone, open Signal's linked devices settings and choose the option to link a new device. Scan the QR code shown in Franz. If the QR code has been visible for a while, refresh the linking view in Franz and scan the new code. Expired codes are normal and only mean the linking attempt timed out.

Signal generally expects one active desktop-style linked session for this Franz setup. If another desktop session is already linked and Signal refuses the new link, remove an old or unused linked desktop device from Signal on your phone, then try linking Franz again.

After linking, keep the phone reachable until the first sync finishes. If messages do not appear immediately, leave Franz open for a short time. For persistent failures, restart Franz and start the linking flow again with a fresh QR code rather than reusing a stale one.
