A Family Handyman report says smart-home devices left in a property may still be linked to a previous owner’s account, and their access can be difficult to spot. Security specialists recommend treating inherited devices as potentially accessible until they have been reset, transferred or replaced, and securing the home’s router and access codes.
Smart-home devices left behind after a property sale may remain connected to a previous owner’s account, potentially allowing remote access to cameras, locks or other equipment, according to a Family Handyman report. The report cites cybersecurity specialist Kurtis Baron, who advises new owners to assume inherited devices could still be accessible until they have been checked and reset or transferred.
There is no reliable visual check for whether a device is still linked to someone else’s account, the report says. Nathan Connell, founder and editor of Future Technology, recommends trying to register each device through its manufacturer’s app. If the app indicates that another person already owns it, the device may still be attached to a previous account. Some companies have formal transfer procedures: the report points to Ring’s ownership-transfer process for cameras and doorbells.
New owners should also inspect each device’s app for unfamiliar users or shared access. Connell warns that people previously authorized by the former owner may retain remote access. That could include access to camera feeds, smart locks or garage doors, depending on the equipment and the permissions still in place. The report does not say that every inherited device remains accessible; it recommends checking rather than assuming access has been removed.
Baron recommends resetting inherited cameras, alarms, locks, thermostats and connected appliances, following the manufacturer’s instructions to remove old accounts and register devices under the new owner’s account. Keypad locks and alarm panels may retain old PINs, Connell says, so owners should delete existing codes, create new ones and remove guest access. The Federal Trade Commission notes that some connected products, including light bulbs and security systems, may be difficult to recognize as smart devices.
Remote Access Can Outlast a Sale
A property transfer does not automatically establish that every connected device and account has been transferred or cleared. If old permissions or codes remain active, a former owner or another person with shared access may be able to reach parts of the home remotely. That creates a privacy and security concern for new residents, particularly when cameras, locks or alarm systems are involved.
Taking stock of connected equipment is therefore part of moving in, alongside changing physical locks. The report recommends treating the router as part of the security check: the FTC describes it as central to the privacy of internet-connected devices, while Baron advises getting a new router, setting a new Wi-Fi password and reviewing the list of connected devices. These steps help the new owner establish control over the network their devices use.
Resetting is not always enough. If a device cannot be fully reset or no longer receives security updates, Baron recommends replacing it. Until ownership is confirmed and access is under the new owner’s control, the report advises not relying on inherited smart locks or cameras for protection.

Device Accounts Need Their Own Handover
The report draws on interviews with Baron, an offensive security specialist at Echo Secure, and Connell, and cites guidance from the Federal Trade Commission, Ring and Google Home and Nest Help. The FTC advises people buying or selling a smart home to account for connected features, including devices that may not be obvious to a new resident. Google’s moving guide explains that some Nest products require the former owner to remove the device from their account before a new owner can set it up.
That distinction matters because a device can physically stay with the house while its digital ownership remains tied to an individual account. Manufacturers’ procedures differ: some support a direct transfer, while other devices may require the previous owner’s cooperation or help from the manufacturer. The report recommends asking sellers for a complete device list, manuals, hub details and transfer instructions before closing, and asking them to remove their accounts and revoke access for anyone they had authorized.
Baron also suggests putting a requirement in closing paperwork that the seller remove access to smart devices included in the sale. The source presents this as a recommendation, not as a universal legal requirement. It gives buyers a clearer handover point and a chance to set up their own accounts and passwords.
“It is much safer to just assume the old owner can still access them.”

What Device Access Cannot Reveal
The source report does not provide data on how often previous owners retain access, nor does it identify a single test that works for every brand and device. A registration warning or unfamiliar shared user can signal an account issue, but device capabilities and transfer rules vary. It is also not clear from the source whether a given former owner—or anyone they previously authorized—still has active permissions in a particular home.
Some devices may require the seller to remove them from an account, while others may be recoverable through a manufacturer’s transfer process. Owners should check the specific product’s instructions or contact its manufacturer. The report also gives no jurisdiction-specific advice on closing paperwork; buyers should not treat its suggested clause as a substitute for local legal guidance.

A Move-In Security Checklist
New homeowners can begin by making an inventory of all connected equipment, including devices that may be less obvious, then check manufacturer apps for ownership status and shared users. Follow each manufacturer’s directions to remove the former account, perform a factory reset and register the device under a new account. Replace old keypad and alarm codes, remove guest permissions, and change the Wi-Fi password. Review the router’s connected-device list and consider replacing equipment that cannot be securely reset or no longer receives updates.
For a future purchase, ask the seller for the connected-device list and setup materials before closing, and ask for written confirmation that accounts and previously granted access have been removed. Where a device remains attached to another account, contact the seller or manufacturer rather than relying on it for security while ownership is unresolved. The source does not identify a new policy or a scheduled follow-up; the practical next step is for each new owner to verify control device by device.

Key Questions
How can I tell if a previous owner still has access to a smart device?
Check the manufacturer’s app for ownership status and unfamiliar shared users. Connell recommends trying to register the device; a message that it is already owned may mean it remains linked to another account. There is no single visual check that confirms access has been removed.
Which smart-home devices should I reset after moving in?
The report recommends checking and resetting inherited cameras, alarms, locks, thermostats and connected appliances. Also look for less obvious connected products, follow the maker’s instructions, and check keypad and alarm codes and guest access.
Should I replace an inherited smart device?
Not necessarily. Some devices can be transferred or reset. Baron recommends replacing equipment that cannot be fully factory reset or is outdated and no longer receives security updates. Check with the manufacturer if the account transfer is unclear.
Why should I change the router or Wi-Fi password?
Connected devices commonly use the home router to reach the internet. The report recommends setting a new Wi-Fi password and checking for unfamiliar devices on the network; Baron also suggests replacing the former owner’s router.
What should I ask the seller before closing?
Ask for a list of connected devices included in the sale, their manuals, hub information and account-transfer instructions. The report also recommends asking the seller to remove their accounts and revoke access for anyone they had authorized.
