What is outside the scope of security updates?
安全性更新不涵蓋哪些內容？
Security updates don’t address vulnerabilities that result from a device being used in a way that it wasn’t intended, or that might compromise its security. For example:
Devices that aren’t properly factory reset before being given to someone else
Accounts that don’t use 2-step verification
Devices made by other manufacturers that haven't been assessed by Google and may have access to your network and Google Nest devices
如果安全漏洞的產生原因是裝置使用方式不當，或使用方式本來就可能會影響裝置安全性，那就不在安全性更新的涵蓋範圍內。例如：
裝置在交給他人前並未妥善恢復原廠設定
帳戶未採用兩步驟驗證
裝置是由未經過 Google 評估的其他製造商所打造，且或許能夠存取你的網路和 Google Nest 裝置
