How to Share WiFi Without Giving Out the Password

Updated 29 September 2026 · 6 min read

The easiest way to share WiFi without giving out the password is a WiFi QR code: guests scan it with their phone camera and connect without ever typing or hearing the password. For one-off sharing with friends, iPhone and Android also have built-in sharing features. For any business, pair the QR code with a separate guest network, because a QR code still contains the password.

What are the ways to share WiFi without the password?

For a home with the occasional visitor, the phone features are fine. For a business with a steady stream of customers, a printed QR code on a guest network is the practical choice because nobody has to hand over their phone or stop work.

How does a WiFi QR code let people connect without typing?

A WiFi QR code stores your network name, security type and password in a standard format: WIFI:T:WPA;S:NetworkName;P:Password;;. When someone scans it, their phone reads the details and offers to join.

• iPhone: the built-in Camera app reads WiFi QR codes on iOS 11 or later.
• Android: most phones on Android 10 or later can scan with the Camera or Google Lens. Some older or less common models need Google Lens or a QR scanner app.

You can make one free with GuestNet at app.guestnet.my: enter your guest network details, pick a design, test-scan and export a 300 DPI PNG or PDF. GuestNet escapes special characters such as ; , : " \ automatically, which is a common reason homemade codes fail. If yours will not scan, see why a WiFi QR code is not working.

How do I share WiFi from an iPhone?

iPhones can pass a WiFi password to another Apple device without showing it:

1. Make sure your iPhone is unlocked, connected to the WiFi and has Bluetooth turned on.
2. Your guest's iPhone, iPad or Mac should be nearby, and you should be in each other's contacts.
3. Your guest selects your network on their device.
4. A prompt appears on your iPhone asking to share the password. Tap Share Password.

This only works between Apple devices, and only when you are physically there. It does not help an Android guest, and it is not practical for a restaurant with dozens of customers.

How do I share WiFi from an Android phone?

Most recent Android phones can display a QR code for the network you are connected to:

1. Open Settings and go to Wi-Fi (on some phones it is under Network or Connections).
2. Tap the network you are connected to, or the gear icon next to it.
3. Tap Share. You may need to confirm with your fingerprint, face or PIN.
4. A QR code appears on screen for your guest to scan.

Menu names vary between Samsung, Xiaomi, OPPO, vivo and other brands. Some phones also show the password in text under the QR code, so be mindful of who is looking at your screen.

Does a WiFi QR code really hide the password?

Only partly. A QR code keeps the password out of sight: nobody has to say it aloud, write it on a whiteboard or type it on a shared device. But the password is stored in the code as plain text, not encrypted.

So a QR code solves convenience, not secrecy. The way to protect your business devices is to make sure the password on the card only unlocks a network you are happy to share.

Why should I set up a separate guest network?

A guest network is a second WiFi network from the same router, with its own name and password. It keeps customers away from your POS, CCTV, printers and office laptops.

• Check your router. Most modern routers, including ISP-supplied ones from Unifi, Maxis, TIME and CelcomDigi, have a "Guest Network" or "Guest WiFi" option. The exact menu varies by model, so check the router's manual or your ISP's support pages.
• Use WPA2 or WPA3 security on the guest network.
• Turn on client or AP isolation if available, so guest devices cannot see one another.
• Never put your main network or router admin password on a public card.
• Change the guest password periodically, then re-export and reprint your QR card.

A note on privacy: in GuestNet, the QR preview is generated in your browser and your WiFi password is never saved in our database. It is sent once over HTTPS at export time to render the file. The exported file contains the QR code, so it encodes the password; we keep only the latest export per card per format for re-download, and delete it when you delete the card or account. Details are in our Privacy Policy.

Frequently asked questions

Does a WiFi QR code hide the password?

It hides the password from casual view, but it does not encrypt it. The password is stored as plain text inside the code, so anyone with a QR scanner app can read it. Use a separate guest network so that is not a problem.

Can I share WiFi from my iPhone to an Android phone?

Not with the iPhone share-password prompt, which only works between Apple devices. For Android guests, use a WiFi QR code instead. A printed card works for both iPhone and Android.

What is the best way for a business to share WiFi?

Set up a separate guest network with WPA2 or WPA3, then display a printed WiFi QR code for it on tables, the counter or the wall. Staff do not need to hand over their phones, and your main network stays private.

Do I need to reprint the QR code if I change the password?

Yes. The password is part of the code, so an old card will stop working. In GuestNet your design is saved, so you only need to enter the new password, export again and reprint.
