A Family Handyman report says smart home devices left by a seller may remain connected to the previous owner’s account, and there is no reliable way to tell by looking at them. Security specialists recommend checking each device and its shared users, resetting or transferring it, and securing the home router and access codes.
Smart cameras, locks and other connected devices left in a home may still be linked to the previous owner’s account, according to a Family Handyman report on securing smart-home equipment after a move. Because the link may not be visible on the device, cybersecurity specialist Kurtis Baron advises new owners to assume inherited devices could still be accessible until they have checked and reset them.
The report recommends making an inventory of connected equipment, including cameras, alarm systems, smart locks, thermostats and appliances. Some devices can be difficult to spot: the Federal Trade Commission warns that items such as light bulbs or security systems may not be obvious as internet-connected products. A manufacturer’s app can help identify whether equipment is already registered to another user. If the app shows that someone else owns it, the device may still be associated with the former owner’s account.
New owners should follow each manufacturer’s instructions to remove an old account, complete a factory reset where available, and register the device under their own account. They should also check the app’s list of shared users and remove unfamiliar people. For keypad locks and alarm panels, Nathan Connell, founder and editor of Future Technology, recommends deleting existing PINs, creating new ones and removing guest access. Some products have a formal transfer process; Ring, for example, provides an ownership-transfer process for previously registered cameras and doorbells, while some Google Nest devices may need the previous owner to remove them first.
The report also advises securing the home network: set a new Wi-Fi password, review connected devices and consider replacing a router left by the seller. Baron recommends replacing devices that cannot be fully reset or no longer receive security updates. A device linked to an old account does not automatically need to be discarded, however; manufacturers may be able to transfer ownership or restore access.
Who May Still Control Connected Devices
Unremoved accounts and shared permissions can leave a former owner or another authorized user able to access some devices remotely. Connell said that access could include unlocking doors, opening a garage or viewing camera feeds. The report does not establish that this is happening in any particular home; it identifies a risk new owners may not recognize while moving in.
That makes device setup part of taking control of a property, alongside changing physical locks. A smart lock or camera should not be relied on for security until the new owner has confirmed they control its account and access settings. Router and Wi-Fi changes matter because connected devices typically use the home network to reach the internet, the FTC says.

Device Handoffs Can Leave Accounts Linked
Smart-home devices are often managed through manufacturer apps and online accounts rather than only through controls on the hardware. As the FTC’s guidance on buying or selling a smart home notes, some connected features may be hard to identify. That can make a handoff incomplete even when the seller leaves equipment behind and the buyer can physically operate it.
The source report draws on advice from Baron and Connell and guidance from the FTC, Ring and Google Home and Nest Help. It recommends asking sellers for a list of included connected devices, manuals, hub details and transfer instructions. Sellers can also confirm that their accounts and any shared users have been removed; Baron suggests putting that requirement in the closing paperwork.
“It is much safer to just assume the old owner can still access them.”

Access Must Be Checked Device by Device
There is no universal visual check that reveals whether a former owner still has access, and the source report gives no estimate of how often this occurs. The result can depend on the manufacturer, device model, account settings and whether the seller completed an official transfer. Some products may require action by the previous owner or help from the manufacturer before a new owner can register them.
The report also does not identify a single reset procedure that works for every device. Owners should consult the product maker’s instructions and avoid assuming that a factory reset is possible or sufficient in all cases. It remains unclear whether any particular inherited device is exposed until its account, user list and network connections have been checked.
Secure Devices During the Move
New homeowners can start by listing every connected device and checking each one through its manufacturer’s app or support process. They should remove unfamiliar users, transfer or reset devices as directed, replace old codes, and update Wi-Fi credentials and router settings. If an account transfer is blocked, contact the manufacturer; until control is confirmed, do not rely on an inherited smart lock or camera for protection.
For future sales, buyers can request a device inventory, manuals and transfer details before closing. Sellers can remove their accounts and revoke shared access, while the closing paperwork can specify that access to included smart devices must be removed. The next step for any individual homeowner is a device-by-device check; the source report does not identify a broader regulatory action or deadline.
Key Questions
How can I tell if a previous owner still has access?
There is no reliable way to tell just by looking at a device. Try registering it through the manufacturer’s app and check its shared-user list for unfamiliar accounts.
Which devices should I check after moving in?
Check connected cameras, alarms, locks, thermostats, appliances and less obvious devices such as smart bulbs. Review any hubs and home-network equipment as well.
Do I have to replace every device linked to the seller?
No. Some manufacturers support account transfer or can help restore control. The report recommends replacement when a device cannot be fully reset or no longer receives security updates.
What should I change on smart locks and alarms?
Delete old PIN codes, create new ones and remove guest access. Follow the manufacturer’s instructions to reset or transfer the device and register it to your own account.
What should I ask the seller to provide?
Request a list of connected devices, manuals, hub information and account-transfer instructions. Ask the seller to confirm that their accounts and previously authorized users have been removed.
