How does a device connect to my Google Account?
裝置如何與我的 Google 帳戶建立連結？
Any time you use your Google Account to sign into a phone, computer, app, or connected home device, they’re connected. Make sure you sign out of devices you don’t own or control, and check your Google Account for devices you don’t recognize.
只要你使用 Google 帳戶登入手機、電腦、應用程式或智慧聯網家庭裝置，帳戶就會與裝置建立連結。請務必將帳戶從你不具備擁有權或控管權的裝置上登出，並檢查 Google 帳戶中是否有陌生裝置。
