How do I secure my smart home from hackers?

Start with a strong, unique password for your Wi-Fi network and every smart device. Change default passwords immediately after setup. Enable two-factor authentication on your smart home accounts. Keep all device firmware and apps updated. Create a separate guest Wi-Fi network for your smart home devices to isolate them from your computers and phones. Disable features you do not use, like remote access for devices that only need local control. Choose reputable brands that provide regular security updates.
