A connected home is only as secure as its least-maintained device. This recurring smart home security audit gives you a practical way to review accounts, passwords, updates, privacy settings, cameras, guest access, and network controls without needing specialist knowledge. Use it monthly or quarterly, and repeat it after adding a device, changing household members, replacing your router, or receiving a security alert.
Overview
Smart speakers, cameras, doorbells, locks, thermostats, lights, appliances, and hubs often rely on several layers of access: a device account, a mobile app, a home Wi-Fi network, cloud storage, and integrations with other services. A weakness in any one layer can expose more information or control than you intended.
The goal of a security audit is not to make every setting as restrictive as possible. It is to confirm that each device still has the access it needs—and no more. Before you begin, make a simple inventory of connected products, including devices that are easy to forget, such as televisions, robot vacuums, printers, plugs, hubs, and old phones or tablets used as controllers.
| Audit area | What to verify | Action if it is unclear |
|---|---|---|
| Account access | Only current household members can sign in | Remove former users and review shared accounts |
| Passwords | Important accounts use unique passwords | Replace reused or easily guessed passwords |
| Multifactor authentication | Available protection is enabled | Turn it on and store recovery details securely |
| Firmware and apps | Devices and control apps are up to date | Install updates or check the support status |
| Privacy | Camera, microphone, location, and data-sharing choices are intentional | Disable permissions that are not needed |
| Network | Router security settings and connected-device list are familiar | Change unknown credentials or investigate unfamiliar devices |
Menu names vary by manufacturer and app version. Look for sections called Account, Security, Privacy, Permissions, Users, Sharing, Device Information, Network, or System. If a setting is not available, record that limitation rather than assuming it is enabled by default.
Checklist by scenario
For every connected device
- Confirm the product appears in your inventory and is still in use.
- Check the account email address, household members, administrators, and shared users.
- Use a unique, strong password for the controlling account. A password manager can make this easier to maintain.
- Enable multifactor authentication where the manufacturer or platform offers it.
- Review recent sign-ins, login alerts, and connected third-party services if those controls are available.
- Check the device, hub, and companion app for firmware or software updates.
- Confirm that automatic updates are enabled when the option is suitable for your household.
For cameras, video doorbells, and microphones
- Check who can view live video, recordings, event history, or audio.
- Remove former household members, temporary contractors, and unused guest invitations.
- Review camera and microphone permissions on every phone, tablet, computer, and smart display that can access the device.
- Use privacy shutters, activity zones, recording schedules, or camera-off modes when available and appropriate.
- Review cloud storage, notification, and data-sharing choices. Confirm that recordings are retained only as long as your household needs them.
- Place cameras carefully so they do not unnecessarily capture private rooms, neighboring property, or sensitive paperwork.
After changing household members
Do not rely only on deleting someone from one app. Review the main smart home platform, individual device apps, shared family groups, voice assistant access, door-lock users, camera viewers, and Wi-Fi credentials. If a former resident knew the network password or had administrator access, changing passwords and reviewing connected devices is more dependable than assuming permissions were removed everywhere.
After replacing the router
- Set a new administrator password and avoid leaving the router's default credentials unchanged.
- Use the strongest security mode supported by your router and connected devices.
- Review the Wi-Fi network name, password, guest network, remote administration, and automatic update settings.
- Reconnect devices deliberately rather than approving every pairing request without checking its identity.
- Inspect the router's client list for unfamiliar phones, computers, cameras, hubs, or appliances.
A separate guest network can help keep visitors and less-trusted devices away from the primary network, but its behavior depends on the router. Check what the guest network can access before treating it as a complete security boundary.
When adding a new device
Before installation, check whether the manufacturer provides ongoing software support, account security controls, and a way to delete data or close the account later. During setup, replace default credentials, install available updates, select only necessary permissions, and document the account used. If the product connects through a hub or standard such as Matter, review both the device manufacturer's app and the platform that controls it. Our Matter compatibility guide can help clarify how devices and platforms fit together.
What to double-check
Support and firmware status
Find the manufacturer's support page or device information screen and record the current firmware version, app version, and support information available for your model. Avoid assuming that a product is protected simply because it is still working. If updates have stopped, the device no longer works with the current app, or the manufacturer provides no clear security information, consider isolating it, replacing it, or removing it from the network.
Permissions and integrations
Review permissions at two levels: the phone's operating-system settings and the smart home service's own account settings. A lighting app may request location access for automation, while a camera may request microphone, storage, or notification access. Keep a permission only when you understand its purpose and need the related feature.
Also inspect integrations with voice assistants, shopping accounts, calendars, automation services, and security-monitoring platforms. Remove connections you no longer use. An integration can remain authorized even after you stop using the original feature.
Encryption and remote access
Look for the manufacturer's explanation of how data is protected in transit and while stored, but do not infer details that are not stated. For your router, review whether remote administration is enabled and whether it is necessary. Disable unused remote-management features, and avoid exposing device-management interfaces directly to the public internet.
Device retirement
Unplugging a device is not the same as retiring it securely. Before selling, recycling, returning, or giving it away, remove it from the account, delete stored data, perform the manufacturer's factory reset, and revoke associated integrations. If the product uses removable storage, handle that storage separately. Finally, remove the old device from the router, smart home platform, and password manager inventory.
Common mistakes
- Using one shared password: A household may find shared access convenient, but it makes accountability and removal difficult. Use individual profiles where supported.
- Ignoring old devices: An unused hub, tablet, camera, or appliance can retain account access. Include products stored in cupboards or disconnected temporarily.
- Trusting default settings: Review privacy, recording, voice activation, sharing, and notification settings instead of assuming the initial configuration fits your household.
- Updating only the app: The mobile app, hub, router, and device firmware can each have separate update controls.
- Approving unexpected login prompts: Reject unfamiliar requests and change the account password if you suspect an unauthorized sign-in.
- Forgetting physical access: A device's reset button, pairing mode, and visible QR code may matter as much as its online account. Keep devices in locations where unauthorized people cannot easily reset or re-pair them.
For broader connected-home planning, see the smart home starter kit guide. If your home includes connected appliances or a robot vacuum, include their apps and accounts in the same review rather than treating them as separate from the smart home.
When to revisit
Put the audit on a repeatable schedule. A monthly review is sensible for homes with cameras, smart locks, or many shared users; a quarterly review may be enough for a smaller setup. Revisit immediately after a security alert, suspected account compromise, router replacement, household move, change in residents, or purchase of a new hub or camera.
Refresh your notes at least every six months and after major firmware or platform updates. Recheck manufacturer support periods, app menu paths, router guidance, default settings, and privacy-policy or data-sharing choices because these details can change. Do not rely on an old screenshot or a saved checklist item if the app has been redesigned.
To finish today's audit, choose one room and work through the inventory from device to router: update the software, confirm account access, remove unnecessary users, inspect permissions, and record anything unresolved. Then set a calendar reminder for the next review and keep the inventory in a secure location. A short, repeatable check is more useful than a one-time setup that no one revisits.
