A Family Handyman report says smart home devices left by a previous homeowner may still be connected to that person’s account or shared with other users. Security specialists advise treating access as unresolved until each device is checked, reset or transferred, and its codes and network settings are changed.
A Family Handyman report warns that smart devices included with a home may remain linked to a previous owner’s account after a sale, potentially leaving that person or people they authorized with remote access. Cybersecurity specialists cited in the report recommend checking and resetting inherited devices rather than assuming a handover has removed old access.
There is no reliable visual check to establish whether a camera, lock or other connected device is still linked to another person’s account, the report says. Kurtis Baron, an offensive security specialist at Echo Secure, advises new homeowners to assume an old owner may retain access until the devices have been checked. Nathan Connell, founder and editor of Future Technology, recommends trying to register devices through their manufacturers’ apps and checking for unfamiliar accounts in shared-user lists. An app indicating that a device is already registered may mean the prior account still needs to be removed or transferred.
The report recommends reviewing cameras, alarms, smart locks, thermostats and connected appliances, including devices that may not be obvious. The Federal Trade Commission has cautioned that items such as light bulbs or security systems can be difficult to identify as smart devices. For each device, homeowners should follow the manufacturer’s process to remove an old account, perform a factory reset where possible, and register it to their own account. Some products require the previous owner to remove the device first; Ring has an ownership-transfer process, and Google’s Nest guidance describes moving devices between households.
Resetting the device is only part of the handover. Connell says old keypad and alarm codes may remain active, so homeowners should delete existing codes, create new ones and remove guest access they do not recognize. Baron also recommends setting up a new router instead of reusing the seller’s equipment, changing the Wi-Fi password and checking the network for unfamiliar connected devices. If a device cannot be fully reset or no longer receives security updates, the report says replacement may be safer than continued use.
Old Accounts Can Reach Beyond the App
Lingering access can affect both privacy and physical security. A person with an account or shared access might be able to view camera feeds or operate connected locks and garage systems remotely, Connell says. That is a risk described by the interviewed specialist, not confirmation that a particular former homeowner has accessed any property.
The issue can be easy to miss because devices may appear to work normally while still linked to an old account. A new owner could then rely on a camera or smart lock without controlling every account or code associated with it. Checking the device, its authorized users and the home network helps establish who can access the system before residents depend on it for security.

A Home Sale May Not Reset Devices
Unlike changing a physical door lock, selling a connected device or leaving it installed does not necessarily remove its account links. Smart devices typically connect to the internet through a home router, and some retain settings, user permissions or registration details until their owner removes them or a reset is completed.
The report draws on advice from Baron and Connell, as well as guidance from the Federal Trade Commission, Ring and Google Home and Nest. It recommends addressing access before or during the sale where possible: sellers can provide a list of included devices, manuals, hub details and transfer instructions, then confirm that accounts and permissions have been removed. Baron suggests making that confirmation part of the closing paperwork.
“It is much safer to just assume the old owner can still access them.”

Device Access Must Be Checked Individually
The report does not provide evidence that a particular former homeowner retained access or used a device after a sale. Whether an old account remains connected depends on the device, manufacturer and transfer process. There is no single check that covers every product, and some manufacturers may require the previous owner’s involvement to release a registered device.
It is also not clear from the supplied material how common post-sale access is or how many devices are affected. The practical advice is precautionary: check each device and account, and do not treat a working device as proof that access has been transferred. The report does not identify a universal factory-reset method or a single deadline for completing the checks.

Build Access Checks Into Closing
Before closing, buyers can ask sellers for a complete device inventory, manuals, hub information and account-transfer instructions. Sellers should remove their accounts and revoke access for people they previously authorized, then confirm that handover in writing. Buyers can use that information to contact manufacturers when an app shows that a device is still registered to someone else.
After moving in, the new owner should work through the inventory: check registration and shared users, reset or transfer each device according to its maker’s instructions, replace old PINs and guest permissions, and secure the router and Wi-Fi. Devices that cannot be fully reset or that no longer receive security updates should be evaluated for replacement. Until control is established, the report advises against relying on an inherited smart lock or camera as the home’s protection.

Key Questions
How can I tell if a previous homeowner still has access?
There is no dependable visual sign. Check the manufacturer’s app for registration status and unfamiliar shared users. If the device appears to belong to another account, contact the manufacturer or ask the seller to complete its transfer process.
Which devices should I check after moving in?
Review cameras, alarms, locks, thermostats and connected appliances, along with less obvious smart products such as connected bulbs. Ask the seller for an inventory and check the home network for devices you do not recognize.
Is a factory reset enough to secure every device?
Not always. Follow the manufacturer’s directions; some devices must first be removed from the previous owner’s account or transferred by that owner. After resetting, register the device under your account and review its users, codes and permissions.
When should I replace an inherited smart device?
The report’s experts recommend considering replacement if a device cannot be fully reset or no longer receives security updates. A device linked to an old account may still be recoverable through its manufacturer, so replacement is not automatically required.
What should sellers provide at closing?
Sellers can provide a list of included devices, manuals, hub details and transfer instructions, and confirm that their accounts and previously authorized users have been removed. Baron suggests recording that access removal in the closing paperwork.
