A Family Handyman report says smart home devices left in a new property may remain linked to a previous owner’s account, and there may be no visible way to tell. Security specialists recommend treating inherited devices as potentially accessible until they are reset, transferred and registered to the new owner.
A Family Handyman report warns that cameras, locks, thermostats and other smart devices left in a home may still be linked to a previous owner’s account, potentially preserving remote access after a sale. The report advises new homeowners to assume inherited devices may remain accessible until they have checked ownership, reset the equipment and set up their own accounts.
There is no reliable visual check for whether a device is still connected to someone else’s account, according to Kurtis Baron, an offensive security specialist at Echo Secure, cited by Family Handyman. Nathan Connell, founder and editor of Future Technology, recommends trying to register each device in its manufacturer’s app. If the app reports that another person owns it, the prior account may still be attached. Some manufacturers provide transfer procedures; Ring, for example, has an ownership-transfer process for registered cameras and doorbells.
Homeowners should also inspect each device’s app for shared users or unfamiliar accounts. The devices to check include security cameras, alarms, smart locks, thermostats and connected appliances. The Federal Trade Commission cautions that some connected equipment, including light bulbs and security systems, may not be easy to identify as smart devices. Manufacturer instructions can explain how to remove an old account, carry out a factory reset and register the device under a new account. Some products may require the seller to remove them first.
Resetting a device does not necessarily remove every access route. Connell told Family Handyman that old keypad PINs and alarm codes may remain active, so new owners should delete existing codes, create new ones and revoke guest access. The router and Wi-Fi network also need attention: the report recommends setting a new Wi-Fi password, checking the list of connected devices and considering a new router rather than reusing the seller’s equipment.
Securing Access After a Home Sale
Connected devices can give authorized users more than control over settings. As Connell told Family Handyman, a person with retained access could potentially unlock doors, open a garage or view camera feeds remotely. That makes account cleanup part of a move-in security check, alongside changing physical locks, rather than a matter of convenience alone.
The risk depends on the equipment and how it was configured; the report does not establish that previous owners routinely retain access or that any particular home has been compromised. But a seller’s departure does not automatically prove that every app account, entry code or shared-user permission has been removed. Until ownership is confirmed and access is reset, new owners may not know who can control or view inherited devices.
There is also a practical limit: a device may not be transferable or fully reset, and older equipment may no longer receive security updates. The report says Baron recommends replacing devices that cannot be fully reset or are outdated. For products that are awaiting an ownership transfer or manufacturer support, homeowners should not rely on them for security in the meantime.

What Sellers and Buyers Should Document
The report’s advice draws on guidance from the Federal Trade Commission, Ring and Google Home and Nest support materials, as well as comments from Baron and Connell. Google’s moving guide says some Nest devices require the former owner to remove them before a new owner can set them up. These processes vary by product, so one reset method may not apply across a whole home.
Before closing, Connell recommends asking the seller for a complete list of included connected devices, along with manuals, hub details and account-transfer instructions. The FTC recommends leaving manuals that describe smart features, including features that may be hard to spot. Sellers should remove their accounts and revoke access for people they previously authorized. Baron suggests including a written requirement in closing paperwork that access to included smart devices has been removed.
After moving in, buyers can work through the inventory device by device: identify the manufacturer and model, check the app and shared-user list, follow the official transfer or reset process, then set new credentials. This approach also helps catch less obvious equipment, such as smart bulbs or a connected alarm panel, that may otherwise be overlooked.
“It is much safer to just assume the old owner can still access them.”

Which Devices Still Have Access
The report does not identify a universal test that can confirm whether a previous owner or a former guest retains access to every device. The result depends on the manufacturer, account setup and whether the product supports a transfer or reset. An app showing an unfamiliar owner or shared user is a warning sign, but the report does not provide a single method for checking every brand.
It is also unclear how many homes or devices are affected; no prevalence data or cases of unauthorized access are cited. A device that remains linked to an old account is not, by itself, proof that anyone has accessed it. Homeowners who cannot transfer or reset equipment should contact the manufacturer and avoid relying on it for protection until control is established.

Steps Before Relying on Devices
New owners can begin by listing every connected device and locating its official app and setup instructions. They should check ownership and shared access, use the manufacturer’s transfer process where available, then factory-reset and register devices under their own accounts. They should replace old entry codes, remove guest permissions, change the Wi-Fi password and review the router’s connected-device list.
If a product cannot be fully reset, is unsupported or remains attached to another account, the next step is to contact the manufacturer about recovery or transfer options. Consider replacement if control cannot be established or the device no longer receives security updates. Future buyers can ask for a device inventory and written confirmation that the seller has removed accounts and permissions before closing.

Key Questions
Can a previous homeowner still access smart devices after moving out?
Possibly. Family Handyman reports that devices may remain linked to a former owner’s account or retain shared access. Whether that applies depends on the device and its setup.
How can I check whether a smart device is registered to someone else?
Try registering it through the manufacturer’s app and check the app’s owner and shared-user lists. Follow the maker’s instructions if the product requires a transfer or reset.
Which devices should I check after buying a home?
Check cameras, alarms, smart locks, thermostats and connected appliances, along with keypad codes, alarm PINs, hubs and smart bulbs. The FTC says some devices may be difficult to recognize as connected equipment.
Should I replace a smart device that is still linked to the seller?
Not necessarily. Some manufacturers support ownership transfers or can help restore control. The report recommends replacing devices that cannot be fully reset or are outdated; do not rely on a device for security while access remains unresolved.
What should sellers provide before closing?
Ask for an inventory of included smart devices, manuals, hub details and transfer instructions, plus confirmation that the seller has removed accounts and revoked shared access. The report says buyers can ask for that obligation to be included in closing paperwork.
