How to share WiFi password with guests safely: put them on a separate guest network first. In person, show a QR code or use your phone's built-in Wi-Fi sharing so nobody types anything. If you're sending it in advance, use a one-time link that expires, not a text or listing message that sits around forever.
Key takeaways
- Set up a guest network so visitors never get your main Wi-Fi password or access to your devices.
- In person, use iPhone password sharing, an Android QR code or a printed QR card.
- When sending ahead of arrival, a one-time link keeps the password out of permanent message threads.
- A link can't stop a guest saving the password, so rotate the guest password regularly.
- Never use the password printed on the router sticker, and keep the router admin password private.
How to share WiFi password with guests in person
If the guest is standing in your hallway, don't read the password out loud or hand over a sticky note. Your phone can do the job, and nobody has to type a 20-character string on a tiny keyboard.
iPhone to iPhone (or Mac)
When an Apple device tries to join a network your iPhone is already on, your phone can offer to share the password. Both devices need Wi-Fi and Bluetooth turned on, need to be close together, and the guest's Apple ID email or phone number needs to be in your contacts. Tap Share Password when the prompt appears.
Android
On most Android phones, open Settings, go to Wi-Fi, tap the network you're connected to and choose Share. After you confirm with your PIN or fingerprint, the phone shows a QR code. The guest points their camera at it and joins.
A printed QR code
For a rental or an office reception desk, a printed QR code works on both iPhone and Android. Generators turn your network name and password into a code using the standard WIFI:T:WPA;S:NetworkName;P:password;; format. Use a tool you trust, since you're typing your password into it.
Remember that a printed code is the password. Anyone who photographs it can join.
All three methods are fine for in-person sharing. The password never lands in a chat log, and you can see exactly who you're giving it to.
Should you set up a guest Wi-Fi password?
Yes. Before you worry about how to send the password, decide which password you're sending. Giving guests your main network password puts them on the same network as your laptop, printer, smart lock and security cameras.
Most home and small-office routers have a guest network option in their admin page or app. Turn it on and you get:
- Isolation. Guests get internet access but, with the right setting, can't see or reach devices on your main network. Look for an option along the lines of "allow guests to access local network" and switch it off.
- A password you can change freely. Rotating the guest Wi-Fi password doesn't knock your own devices offline, so you'll actually do it.
- A clean cut-off. When a tenant moves out or a contractor finishes, you change one password and they're off.
Give the guest network its own strong password, at least 12 characters, using WPA2 or WPA3. Three or four random words strung together are easy to type and hard to guess. CISA's home network security guidance covers the router basics, including changing the default admin password.
How to share a Wi-Fi password securely before guests arrive
Remote is where it goes wrong. A holiday rental owner wants the guest online the moment they walk in. A landlord wants the new tenant connected on move-in day. A small office wants a visiting consultant ready to work at 9am.
So the password goes out days early by text, email or platform message, and it stays there. A Wi-Fi password isn't your bank login, but a static one sitting in dozens of message threads ends up with everyone who ever stayed. A one-time link limits the copy to the person who needs it, for as long as they need it.
Steps to send it with a self-destructing note
- Open SecureNotes and create a self-destructing note. There's no account or sign-up.
- Paste the details. Network name, password and anything useful, such as "Join the network ending in -Guest. The router is in the hall cupboard if you need to restart it."
- Choose when it self-destructs. For a booking a few days out, pick 7 days. For views, 1 is tightest; choose 3 if the guest will probably open it on both a phone and a laptop. The link stops working at whichever limit comes first.
- Add the extras you want. An optional passcode helps if the link might be forwarded or land in a shared family inbox. Turn on the read notification so you know the guest opened it.
- Send the link through the booking platform, email or text. SecureNotes can also email the link to the guest for you.
- Send the passcode another way. If the link went by email, send the passcode by text or through the booking app, so one intercepted message isn't enough.
- Tell the guest to save it. Once the views run out, the link is gone. Ask them to copy the password or join the network as soon as they open it.

Which way of sharing a guest Wi-Fi password is best?
It depends on whether the guest is in front of you and how often you rotate the password.
| Method | Best for | What it needs | Main downside |
|---|---|---|---|
| Phone sharing (iPhone prompt, Android QR) | Visitors in person | Guest physically present | No help for remote guests |
| Printed QR code or card | Rentals, offices, waiting rooms | Physical access to the space | Anyone can photograph it; must reprint after each change |
| Booking platform check-in info | Airbnb and similar rentals | A confirmed booking | Stays in the guest's app until you change the password |
| Plain text or email | Quick, familiar | Phone number or email | Sits in both inboxes, backups and group chats indefinitely |
| One-time link | Sending ahead of arrival | Guest's email or number | Guest can still save or share the password after reading |
The short version: share in person when you can, use a one-time link when you can't, and rotate the guest password so whatever's left lying around goes stale.
What should Airbnb hosts do with the Wi-Fi password?
Airbnb and similar platforms let you add Wi-Fi details to the check-in information, which is typically shown to confirmed guests around arrival. That's a reasonable channel, as long as you treat the password as something every past guest knows.
- Never put it in the public listing. Not in the description, not in a photo. A router sticker visible in a listing photo has leaked plenty of passwords.
- Keep guests off your smart devices. Locks, cameras, thermostats and noise monitors belong on a network guests don't join. If they share one, a curious guest can poke at them.
- Rotate on a schedule. Changing the Airbnb Wi-Fi password between every stay is ideal but means updating the platform, the printed card and any QR code. Monthly, or after any stay you're uneasy about, is a sensible minimum.
- Keep the router admin password private and changed from the default. The Wi-Fi password gets guests online. The admin password lets them change your network.
If you rotate between stays, a fresh one-time link per booking fits neatly: new password, new note, sent a few days before arrival, set to expire after 7 days.
Common mistakes when sharing a guest Wi-Fi password
- Handing out the main network password. The most common one, and it turns a small favour into full access to your home or office network.
- Using the password printed on the router. The sticker password stays valid until you change it, and anyone who sees the router can read it.
- Posting it in a group chat. Family reunions, wedding parties, team channels. Everyone in the chat keeps it, including people who leave the group later.
- Never changing it. A password you've shared with 200 guests over three years isn't a secret any more.
- Expecting the link to stop copying. A one-time link controls the link, not what the guest does next. They can screenshot it or pass it on. What a one-time secret link guarantees covers the limits. Rotation is your real control.
- Setting the expiry too short. A 1-hour limit for a guest arriving next week means a dead link and a late-night phone call. Match the time limit to the arrival date.
- Sending the passcode with the link. If both are in the same message, the passcode adds nothing.
When should you change the guest Wi-Fi password?
Change it whenever someone who shouldn't keep access might still have it:
- After a tenant moves out or a long-term guest leaves.
- When a contractor or temporary staff member finishes.
- If the password appears somewhere public: a review, a listing photo, a social media post.
- When your router's app shows devices on the guest network you don't recognise.
- On a routine schedule: monthly for a busy rental, quarterly for a small office.
Afterwards, reprint the card or QR code and update your check-in info. A stale QR code on the fridge is the most common reason guests can't connect after a change.
For a small office, keep staff laptops on the main network and point visitors to the guest one. When a regular visitor needs the new password, you can send a secure note rather than adding it to a shared channel.
Frequently asked questions
Can guests on my Wi-Fi see what I'm doing online?
Not your encrypted browsing, since most sites use HTTPS. The bigger risk on a shared network is that guests can see and try to connect to your devices, such as printers, smart speakers, cameras and file shares. A guest network with local access switched off keeps visitors on the internet and away from your own equipment.
Is it OK to leave the Wi-Fi password on a card in a rental?
Yes, for a guest network you rotate. It saves guests messaging you and keeps the password off your phone. Treat the card as public: anyone in the property, including cleaners and past guests, can photograph it. Never print your main network password or router admin password, and reprint the card each time you change the guest password.
How do I find my Wi-Fi password so I can share it?
On recent iPhones, go to Settings, then Wi-Fi, tap the info icon next to your network and tap Password. On many Android phones, the Share screen shows the password beneath the QR code. You can also log in to your router's admin page or app, where the Wi-Fi and guest network settings show the current password.
Should I hide my guest Wi-Fi network name?
No. Hiding the network name doesn't add real protection, because the name can still be picked up by common tools and by devices that have joined before. It mostly makes life harder for legitimate guests, who then have to type the name manually. A strong password, WPA2 or WPA3, and regular rotation do far more.
Can I limit how long a guest can use my Wi-Fi?
Some routers let you schedule the guest network or set access time limits, so check your router's app. If yours doesn't, changing the guest password is the reliable cut-off. Note that a one-time link's expiry only controls the link itself. Once a guest has joined the network, their device stays connected until the password changes.
