A Family Handyman report warns that cameras, locks, alarms and other smart devices left in a home may still be connected to a previous owner’s account. Security specialists recommend checking each device’s account status, resetting it and replacing equipment that cannot be secured or no longer receives updates.

Smart devices left behind after a home sale may still be linked to the previous owner’s account, potentially leaving that person or users they invited with remote access to cameras, locks, alarms or other equipment, according to a Family Handyman report. Security specialists cited in the report recommend treating inherited devices as potentially accessible until ownership is checked and the equipment is reset or transferred.

There is no reliable visual sign that an inherited device has been removed from its former owner’s account. Kurtis Baron, an offensive security specialist at Echo Secure, advises new homeowners to assume the old owner could still have access until they verify otherwise. Nathan Connell, founder and editor of Future Technology, suggests trying to register each device through its manufacturer’s app: a message that it is already registered may indicate that another account remains attached. Some companies, including Ring, provide an ownership-transfer process.

Homeowners should review each device’s app for unfamiliar shared users as well as the primary account. Connell cautions that a former owner or a person previously given access could potentially operate connected door locks or garage controls, or view camera feeds. These are possible risks described by the source, not evidence that a particular former homeowner has retained or misused access.

Baron recommends resetting inherited cameras, alarms, locks, thermostats and connected appliances, following the maker’s instructions to remove old accounts, perform a factory reset and register the device to a new account. Homeowners should also delete old keypad and alarm codes, create new ones, and remove guest permissions. The Federal Trade Commission notes that devices such as light bulbs or security systems may be difficult to identify as smart products, so an inventory should include equipment beyond obvious cameras and speakers.

The developmentA Family Handyman report outlines how new homeowners can check and secure smart devices that may remain accessible to former owners or their invited users.

Why Old Device Access Matters

Smart-home access can reach beyond control of a single appliance. Depending on the device and permissions, a linked account may expose camera footage or allow remote operation of locks, alarms or garage doors. That makes account ownership and access lists a practical part of moving-day security, alongside changing physical door locks.

The home’s network is also part of the security picture. The FTC describes the router as central to privacy for internet-connected devices, since they commonly use it to reach the internet. Baron recommends using a new router rather than relying on equipment left by the seller. New occupants should set a new Wi-Fi password and review the network for devices they do not recognize. These steps can help establish control of the connected-home environment, but they do not replace device-specific resets or account transfers.

There can also be a limit to what a reset accomplishes. Baron recommends replacing equipment that cannot be fully factory-reset or is outdated and no longer receives security updates. Until an inherited camera or smart lock has been transferred and secured, the report advises homeowners not to rely on it for protection.

Securing Devices During a Move

The report frames smart-device access as a handover issue: equipment may be included in a home sale, while its account, permissions and setup details remain tied to the seller. A seller’s removal of a device from their own app, a manufacturer’s transfer procedure and a buyer’s factory reset are not necessarily the same process. Some products require the former owner to remove the device before a new user can register it; Google’s Nest moving guidance is one example cited in the report.

The FTC advises buyers and sellers to account for smart features that may not be obvious. Connell recommends asking before closing for a list of connected devices included in the sale, along with manuals, hub details and account-transfer instructions. Baron suggests including a written requirement in closing paperwork that the seller remove access to included devices. These steps can make the handover clearer, but buyers still need to verify device status and set up their own accounts and credentials after moving in.

“It is much safer to just assume the old owner can still access them.”

Access Depends on Each Device

The report does not establish that former owners generally retain access, or that any specific device has been accessed after a sale. Whether an old account remains connected depends on the product, its setup and whether the seller or manufacturer completed the relevant removal or transfer steps. A device appearing to work normally does not, by itself, confirm who can access it.

Some manufacturers offer ownership-transfer support, but the exact steps vary. It may not be possible to identify every connected product by sight, and the report gives no single test that works across brands. Homeowners should consult each manufacturer’s instructions and contact its support team if an account cannot be removed or ownership cannot be transferred.

Steps for Buyers and Sellers

After moving in, buyers can make an inventory of connected equipment, check each manufacturer’s app for registration and shared users, and follow the product’s directions to transfer or factory-reset it. They should replace old access codes, create new credentials, secure the router and Wi-Fi network, and check which devices are connected. Equipment that cannot be reset or no longer receives security updates may need replacement.

Before closing, sellers can provide a complete device list and manuals, remove their accounts and revoke access for other users. Buyers who cannot confirm a device’s status should contact the maker rather than assume it has been cleared. The report does not identify a new policy or deadline; the next step for each household is a device-by-device handover and security check.

Key Questions

How can I tell whether a previous owner still has access?

Check the manufacturer’s app to see whether the device is already registered, and review its shared-user list for unfamiliar accounts. Because there is no reliable visual check, follow the maker’s ownership-transfer and reset instructions.

Which devices should I check after moving in?

Review inherited cameras, alarms, smart locks, thermostats and connected appliances. The FTC also cautions that some smart products, including light bulbs and security systems, may not be easy to recognize as connected devices.

Is a factory reset always enough?

Not necessarily. Procedures vary, and some products require the former owner to remove the device from their account before a new owner can register it. Contact the manufacturer if the transfer or reset does not work.

Should I replace a smart device left by the seller?

Not automatically. Some devices can be transferred or reset. Baron recommends replacing products that cannot be fully factory-reset or are outdated and no longer receive security updates.

What should I ask the seller before closing?

Ask for a list of connected devices included in the sale, manuals, hub information and transfer instructions. The report also recommends confirming that the seller has removed their accounts and revoked other users’ access.
