How to secure IoT devices added for Halloween décor

By TechHomeTips Editors Published March 2, 2026 Updated October 28, 2026 4 min read Report a correction

Change default passwords on new décor devices, leave the firewall on, and do not forward ports. Remove the devices from the app when you pack them.

A smart plug or camera you added for Halloween should not keep a default password, a public sharing link, or a port forwarded on the router. Secure it when you set it up, and review its schedules and account access when the décor comes down. Do not weaken the firewall to make a device connect.

Step 1: Change the default login

  1. If the device, router, or app account has a default login, replace it before use. Some plugs have no separate device password; secure the account that controls them.
  2. Use a password you do not reuse for email, the router admin, or the door lock. Turn on the extra sign-in check if the app offers one.
  3. Do not put that password on the porch, in the device name, or on the tape label. The tape names the outlet only: labeling devices.

Router habits that stay in place are the home Wi-Fi security checklist. Guest phones do not join this setup. They use the guest network: guest Wi-Fi.

Step 2: Do not expose the device on purpose

Do not forward a port so a plug, a bulb, or a camera is reachable from the internet in a browser. Use the vendor’s app, or do not use remote access. Do not turn Wi-Fi security off so a plug that prefers an open network will join. If it will not join your encrypted network, return it or leave it unplugged.

A separate network can limit device access when the router and device support it, but some apps need local communication. Test a supported IoT or guest network before the event. A separate schedule and name help organization; they do not isolate network traffic: décor schedules. Watt and outdoor limits remain: the smart-plug checklist.

Firmware updates come from the app or the maker’s own update, on a calm afternoon, not from a file a forum attached. If an important security update fails, stop using the device remotely until you can resolve the update with the maker’s instructions. Do not factory-reset the router to finish a plug update.

Step 3: Turn off sharing you did not mean to enable

Cameras: public feeds and neighborhood posting stay off unless you already understand who can see them. Aim at your door, not the street: doorbell privacy. Share only with a person you trust; choose limited permissions and expiry when supported: temporary camera access.

Voice routines do not gain locks or alarms because a new plug was installed: voice routines. A speaker’s quiet hours stay intact: quiet hours.

Step 4: When the season ends, remove what you added

Physically unplug the seasonal device and disable schedules or shares you no longer need. Remove its app entry if you are retiring it or if the maker recommends that step; app removal alone does not disconnect power. Change a password again if you typed it into a shared note. Leave the router firewall on. The audit list for the week after is permissions after Halloween.

A device you do not recognize in the app gets removed if you are sure it is not the modem, the lock, or the only camera you meant to keep. If you are unsure, do not delete your only admin login. Identify it in daylight.

What you should be able to point at

  • Default passwords changed. Extra sign-in on if the app has it.
  • No new port forwards. Wi-Fi encryption left on.
  • Camera sharing limited to people you intended, with expiry or manual revocation planned.
  • Updates only from the maker’s app, not a random file.
  • Seasonal devices unplugged and unneeded schedules disabled.

Example: the plug joined the house network and nothing else

A new outdoor smart plug still has the sticker password. They change it before the string goes up, and they turn on the app’s extra sign-in check. The plug joins the existing encrypted Wi-Fi. They do not forward a port when the app offers “easy remote.” They do not create an open network when the first join fails. They move the plug a few feet closer to the house and it connects. The camera feed stays private. In November they unplug the plug and disable its seasonal schedule; app removal is optional. The router settings look the same as they did in September. The firewall was never switched off.

Questions readers ask

The instructions say to forward a port so the plug works from anywhere. Should we?

No. Use the vendor app on your phone. Do not forward ports for a seasonal plug or camera. If remote control needs a port, skip remote control.

The device will only connect to an open network. Can we turn security off for an hour?

No. Leave encryption on. If the device cannot join your existing Wi-Fi, do not use it. Do not leave an open network running for décor.

A forum has a firmware file that adds features. Should we install it?

Use firmware only from the maker’s app or official support site for your exact model. If an important security update fails, pause remote use and follow the maker’s recovery instructions; do not install a forum file.

Can we put the new plugs on the guest network so they are isolated?

A separate IoT or guest network can reduce access to your main network if the router supports isolation and the device still works there. Test before the event. A device name or separate schedule is organization, not network isolation.

We shared the app password in a group chat by mistake. What now?

Change the password, remove shares you do not recognize, and do not post the new password in that chat. Unplug the device if you cannot get back into the account.
