Smart speakers, cameras, doorbells, televisions, thermostats, and connected appliances may each have an account, microphone, camera, or connection to the home network. Security improves when you treat the setup as a system rather than protecting only your phone or laptop.
Nine steps to improve security
- Change default credentials. Use unique passwords for device accounts.
- Enable multifactor authentication. Turn it on for manufacturer accounts and apps that support it.
- Install updates. Enable automatic updates when practical and check that devices still receive security fixes.
- Secure the router. Change its administrator password and update firmware.
- Separate devices. Use a guest or IoT network if supported; separation reduces exposure but does not make an insecure device harmless.
- Review microphones and cameras. Disable features you do not use and understand recording retention.
- Limit app permissions. Remove old users and integrations.
- Protect physical access. Keep routers and hubs where visitors cannot easily tamper with them.
- Replace unsupported products. Consider isolating or replacing devices that no longer receive security fixes.
Be careful with shared access
Remove old users after a move or change in household access. Follow the manufacturer’s reset process before selling a device. For cameras, review who can view recordings and whether links can be shared onward.
Watch for warning signs
Unexpected account alerts, unknown users, settings that change without explanation, or repeated password-reset messages deserve attention. Check the account through the official app, change credentials from a trusted device, and review active sessions. If a device seems compromised, disconnect it while following manufacturer guidance.

Make a quarterly audit
Keep a list of devices, account owners, update status, and required permissions. Each quarter, check updates, users, and privacy settings.
