⚠️ The most common guest WiFi passwords — avoid every one
These are what people actually set. Each appears in standard cracking wordlists, and several are guessable by anyone who can read your signage or your rental listing:
| Common guest password | Why it fails |
|---|---|
| welcome123 | The single most common guest password worldwide. In every cracking dictionary. |
| guestwifi / guest2026 | The word 'guest' plus a year is a standard mutation rule in cracking software. |
| Business name + year | Attackers try the venue's own name first. So does anyone who reads your signage. |
| Street address or house number | Printed on the listing, visible from the road, in public records. |
| Same as the main network | Defeats the entire point. Guests now have your real credentials. |
| password / 12345678 | Still the most-attempted strings in every attack log ever published. |
| Property or room name | For rentals, this is in the listing title. Guessable before anyone arrives. |
| wifi / internet / connect | Single dictionary words fall in under a second. |
🎲 Guest WiFi password ideas that actually work
Guests read the password off a card, or hear it once at a reception desk, or squint at it on a fridge magnet. That makes a short passphrase the right format — pronounceable, typeable on a phone, and genuinely random.

Clear enough that a tired guest at midnight finds it instantly
☕ Café & Restaurant Guest Names
On-brand, and unambiguous next to five other networks in range
💼 Office & Client Guest Names
Professional enough to put in a meeting invite
How to set up a guest network
Almost every router made since about 2018 supports this, and every mesh system does. The path differs by brand but the shape is always the same:
When to change the guest password
Not on a calendar — when the group with access changes. Every phone that ever connected still holds the credentials and rejoins automatically whenever it's in range.
| Setting | Change it when | Why |
|---|---|---|
| Home | After a party, or when a houseguest leaves | Old devices reconnect silently for years otherwise |
| Airbnb / rental | Between bookings, or monthly at minimum | Every past guest's phone still holds the credentials |
| Café / restaurant | Quarterly, or when printed cards are reprinted | Balances security against reprinting signage |
| Office | Quarterly, and immediately when staff leave | Contractors and ex-employees retain access indefinitely |
| Any | Immediately after a device you don't recognise appears | Assume the password has spread further than intended |
Guest WiFi for Airbnbs and short-term rentals
Rentals have a specific problem: every guest who ever stayed still has the password, and the property name and address are published in the listing — which rules out the two things hosts most commonly use as passwords.
- Never derive it from the listing. Property name, street, house number, and city are all public before anyone books.
- Print a QR code, not a password. Guests scan on arrival. Fewer support messages at midnight, and you can use a password nobody would tolerate typing.
- Rotate between bookings if you can. Monthly is a fair compromise. Reprinting one card is cheap.
- Guest isolation is non-negotiable here. Smart locks, cameras, and thermostats sit on your main network. A stranger sleeping in the property should have no route to them.
- Don't name it after the property. "Apartment 3B Guest" is fine and clear; "SunsetVillaWifi" tells anyone in range which listing they're standing next to.

Frequently asked questions
What are good guest WiFi password ideas?
A 4 or 5 word passphrase like Cedar-Harbour-Lantern-Swift. Guests read it off a card or hear it once, so it needs to be pronounceable and easy to type on a phone. Put the personality in the network name — that's public anyway.
What are the most common guest WiFi passwords?
welcome123, guestwifi, guest2026, the business or family name plus a year, the street address, and reusing the main network password. All are in standard cracking wordlists, and the last one defeats the point of having a guest network at all.
Should guests be on a separate WiFi network?
Yes. It gives visitors internet while isolating them from your printers, NAS, cameras, and smart home devices — and lets you change the guest password freely without re-pairing your own equipment.
How do I set up a guest WiFi network?
Log into your router at 192.168.1.1 or 192.168.0.1, find Guest Network under Wireless settings, enable it, give it its own name and password, and confirm client isolation is on. Mesh systems expose the same setting in their app.
How often should I change my guest WiFi password?
When the group with access changes, not on a schedule. Home: after a party or a departing houseguest. Rental: between bookings, or monthly. Café or office: quarterly, and immediately when staff leave.
What is a good guest WiFi password for an Airbnb?
A 4-word passphrase on a printed card, or better, a WiFi QR code guests scan on arrival. Avoid anything based on the property name or address — both are in the listing. Rotate between bookings if you can.
Can guests see my devices on the guest network?
Not with guest isolation enabled — the default on most modern routers, but worth checking. Look for client isolation or AP isolation. Without it, a guest network is just a second password to the same network.
