Your Cat Sitter Doesn't Need the Doorbell App: A Festive Access Handover

Christmas cover usually starts with a key. A neighbour, a pet sitter, a cleaner, or a temp drafted in for the busiest fortnight of the year gets a spare set, a rough timetable, and a promise that the cat is friendly. Then someone sends the Wi-Fi password over WhatsApp and the handover quietly becomes a digital access problem.

That is not a reason to cancel the sitter. It is a reason to treat access like a loan, not a gift. You want the cat fed, the post brought in, and the shop floor covered. You do not want a guest network password still working in February, a doorbell app logged in on someone else's phone, or a WhatsApp thread holding your alarm code.

Here is a practical handover for UK homes and micro-firms in December 2026.

Put the sitter on the guest network

Your main Wi-Fi is the front door to everything: laptops, NAS drives, printers, smart plugs, maybe the till or a work laptop. A guest network is the side entrance. It gives internet access without letting a device see the rest of the house.

Before you hand over anything, log into the router and check that the guest network is switched on. Give it a different name and a long password that is not the same as your main one. In the router settings, look for a tick box called something like 'allow guest access to local network' or 'client isolation'. You want that off. The guest should reach the internet, not your files.

Test it from a phone that is not yours. If you can cast to the living room TV or see the printer, the guest network is too friendly. Fix that before the sitter arrives.

For a small firm, the same rule applies. Seasonal staff need Wi-Fi, not a tour of the back office. If your router cannot isolate guests, consider a separate travel router for temps or ask your broadband provider for a business router with proper guest controls. It is cheaper than a quiet data incident in January.

The doorbell app is not part of the deal

Smart doorbells, cameras and alarms often have a share feature. Use it properly: add the sitter as a temporary user with their own login, not your master account. If the app only allows one account, do not hand over your password. Change it after they leave and sign out all devices.

Ask yourself what the sitter actually needs. Feeding the cat does not require live footage of every delivery. If a parcel needs bringing in, a text message and a key safe may be enough. The less access that exists, the less you have to claw back.

The same goes for smart locks and alarm panels. Many support temporary codes or time-limited users. Set a start and end date. Do not give the master code. If your system is older and only has one code, change it when you get home. Write the change on your own calendar, not on a note stuck to the fridge.

Invite smart-home helpers, don't inherit them

Alexa, Hive, Nest, smart plugs, robot vacuums: they are useful, and they are also little accounts with permissions. A pet sitter may need the heating on or a lamp to come on at dusk. They do not need the ability to unlock the front door, order shopping, or add themselves to your household.

Use guest access where it exists. If it does not, set routines instead: a lamp on a timer, heating on a schedule, a smart plug for the Christmas tree. That way the house looks lived in without handing over the controls.

For micro-firms, think about the alarm, the till, the card reader and the cloud drive. A temp may need a login for the rota, not the payroll folder. Create a separate account with the minimum permissions, and put the end date in the account name if your system allows it. 'Temp-December-2026' is a useful reminder when you are tired in January.

What never goes in a WhatsApp message

Chat threads are convenient, searchable and backed up. That makes them a poor place for secrets. Never send an alarm code, a key safe combination, a full Wi-Fi password, or a photo of a key in a group chat. Screenshots get forwarded. Phones get lost. Backups keep old messages long after you have forgotten them.

Disappearing messages are not a vault, either. They disappear from the chat, not from the other person's memory or a notification preview.

If you need to share a password, use a password manager's share link with an expiry date, or say it in person and write it on a card the sitter keeps in their pocket. For a small firm, do not drop the alarm code into a seasonal staff group. Use a sealed envelope, a named manager, or a temporary code that expires. The goal is not secrecy for its own sake. It is making sure access has an end date.

The return-day revoke list

When you get home, do not just take the key back and put the kettle on. Spend five minutes closing the digital doors.

Change the guest Wi-Fi password. Remove the sitter from the doorbell, camera and smart lock apps. Delete temporary alarm codes. Check the router's connected devices for anything unfamiliar. Revoke any shared links or calendar invites. If you used a password manager share, expire it now.

For a small firm, remove temp accounts from email, the card reader dashboard, cloud storage and any messaging tools. Check shared folders for 'anyone with the link' access. Ask the temp to sign out of any app on their own phone, and change the password if you are not sure.

Finally, check the key safe. If the code was shared, change it. If the key was left under a pot, move it. Christmas cover is meant to be temporary. The access should be, too.

At McAfeeCom UK, we would rather you spent five minutes on this now than an hour on the phone in January. A good handover is not suspicious. It is simply clear about what is borrowed, what is shared, and what gets switched off when the decorations come down.
