Google Wifi no QR code
Google documents a physical QR on Nest Wifi and Nest Wifi Pro for device setup, while current Google Home WiFi sharing guidance uses Copy, Message, or Email for the network password rather than documenting a universal guest-sharing QR.
Those are different jobs. If a visible setup QR will not scan, use Google's setup-code path. If the physical label is missing, use Google's support route. For reusable guest access, share the password or create a separate WiFi QR from verified details.

Nest Wifi device QR is for setup
Google documents a unique QR label on the bottom of Nest Wifi and Nest Wifi Pro devices that is scanned while adding the device.
An unreadable QR and a missing label have different fallbacks
If the device QR is present but cannot be scanned, Google documents Use setup code. If the QR label itself is missing, Google's current help directs users to customer support for setup assistance.
Current password sharing is app-based without a documented universal WiFi QR
Google Home currently documents Copy, Message, or Email from the Share password flow.
A setup code and a guest-access code can both be called “the QR,” but replacing one does not solve the other.
Use Google's setup QR or setup-code fallback when you are adding the Nest Wifi hardware itself.
Use Google Home's current password-sharing tools or create your own reusable credential QR only when that is the desired output.

Workflow
Identify the purpose of the missing code before choosing the fallback.
Check the bottom device label. If the QR is present but will not scan, use the setup-code option; if the label itself is missing, follow Google's support guidance.
Open Google Home > WiFi > Share password and use the current Copy, Message, or Email choices.
Verify the live network details and create a separate WiFi credential QR for that physical or reusable use case.
The key is determining whether the expected code belongs to device setup or network sharing.
Use the device label or setup-code fallback from the Google Home setup process.
Use the Google Home Share password flow or make a separate tested QR when a permanent sign is the goal.
Comparison
These can both involve scanning, but they are not interchangeable.
A unique code on the Nest Wifi or Nest Wifi Pro device used while adding the hardware in Google Home.
The current Google Home flow exposes the network password for copying or sending; a separate reusable QR can be created only if you need that format.
Questions about missing Nest setup labels and WiFi sharing alternatives.
Google documents the unique setup QR on a label on the bottom of the device.
If the QR is present but will not scan, use the setup-code option. If the QR label itself is missing, Google's current help directs you to customer support for setup assistance.
Google's current password-sharing help documents Copy, Message, and Email rather than a universal QR button.
Yes, if you verify the live network details first and need a separate credential-sharing asset.
No. The device QR is used to add the router or point during setup; guest or household WiFi access is a separate sharing task.
Use Google Home to verify the current WiFi details, then create and test a separate credential QR for the place where guests will scan it.
