Category: Speakers & Displays → Troubleshooting

Issue

During setup or when changing Wi-Fi settings, you may receive the following message:

"This device is already linked to a user. Factory reset the device to change configuration."

This usually means the device was previously connected to another Google account and has not been reset.

Why This Error Appears

Google Nest devices are designed to protect personal information stored on the device.

If the device was previously owned, configured, or linked to another account, it must be reset before it can be connected to a different account or network.
