A guest Wi-Fi password gets handled very differently from your main one. People read it off a card and type it with their thumbs while you stand there waiting. So the best guest password is long enough to be safe and dull enough to say out loud without spelling anything. Here is how to pick one, with some network name ideas at the end.
- Length
- 8 to 63 characters for WPA2 and WPA3. Aim for 15 or more.
- Best pattern
- Three or four random words. Easy to say, hard to guess.
- Avoid
- Lookalike characters such as
0andO, or1andl. - Never
- Your main Wi-Fi password with “guest” stuck on the end.
What makes a good guest password
Length does almost all the work. A WPA2 or WPA3 password can be anything from 8 to 63 characters, and someone trying to crack it offline gets nowhere with a long one. Symbols add less than people think, and they cost a lot at the moment someone has to find the backslash on a phone keyboard.
The UK’s National Cyber Security Centre recommends three random words for exactly this reason. The result is long and still easy to remember. For a guest network that is the right call. Four words is better if you don’t mind the extra typing.
The word that matters is random. A phrase you would naturally say, like a football team and a year, is the first thing a guessing tool tries. Open a book at three random pages and take the first noun on each, or use a password manager’s passphrase generator. People are bad at random. Machines and books are fine at it.
Password ideas, by style
Use these as patterns, not as passwords. Every example on this page is now on the internet, so make your own from the same recipe.
| Style | Looks like | Good for |
|---|---|---|
| Random words with hyphens | kettle-orbit-plum |
Reading aloud. The hyphens tell people where words end. |
| Random words run together | lanternmosscopper |
Typing on a phone. No punctuation keyboard needed. |
| Four words | tulip-garage-violin-salt |
A guest network that stays the same for a year. |
| Words with a number | maple-canoe-47 |
Routers that insist on a digit. |
| Generated string | vT9qL2mWx8Rk |
QR codes only. Nobody should have to type this. |
Characters to keep out
The main troublemakers are characters that look alike in print. A capital O and a zero, or a lower-case l next to a one and a capital I, turn a two-minute job into ten minutes of retyping. Plain lower-case words avoid the whole problem.
If one of them is unavoidable, say because the router generated the password, print the card in a monospaced font such as Consolas or Menlo. Both draw the zero with a slash through it, so nobody has to guess.
Watch the edges too. A space at the start or end of a password is invisible on a card and breaks the login every time. And if you will ever turn the password into a QR code, characters such as ; : and \ have to be escaped inside the code, which some generators get wrong. Our guest Wi-Fi QR code guide covers that.
Passwords not to use
- Anything about you. Surname, house number, street, dog’s name. Guests know these, and so does anyone who has walked past.
- Your main password with a suffix. If
Summer2026is the main network,Summer2026guesttells a guest exactly what to try next. Some routers create the guest password this way by default; check yours. - The router’s generated key, if you’ll read it out. It is secure and it is miserable to dictate.
- Stock phrases.

How often to change it
At home, change it when you’d rather someone stopped using it: a lodger moves out, a builder finishes. Otherwise, leave it. Changing it constantly just means retyping it on everyone’s phone.
A shop or holiday let is different, because the password leaks. Guests photograph the card and post it in reviews. Monthly is a sensible rhythm, and straight away when a member of staff leaves. Changing it means reprinting every sign, which is the strongest argument for a QR code you can regenerate in a minute.
Some venues give up on the password and swap it for an email sign-up page instead. The guest types an email address rather than a code from the wall, and the business ends up with a list of customers who said yes to hearing from it. That’s what CaptureWiFi, a service we also run, is built for.
Guest Wi-Fi name ideas
The network name, or SSID, can be up to 32 characters. Make it obviously different from your main network so nobody joins the wrong one. And keep it free of anything personal: your surname plus “Guest” announces whose house it is to every phone on the street.
| Kind | Examples |
|---|---|
| Plain | Visitors, Garden Office Guest |
| Friendly | Kettle's On, Spare Room, Make Yourself At Home, Wipe Your Feet |
| Jokes | Not The Main One, Pretty Fly For A WiFi |
| Holiday let | The property’s name, e.g. Old Mill Cottage. Guests look for it. |
| Business | The trading name, e.g. Harbour Cafe Free WiFi. Nothing cleverer. |
One caution on the jokes. Everyone within range sees the name, including neighbours you’ve never met. Funny is fine. Rude, or anything aimed at the people next door, tends to go less well than it sounded in your head.
