WiFi QR Code: Share Your Wi-Fi Password With One Scan (iPhone & Android)

What a WiFi QR code does

A wifi qr code ends the ritual of spelling your password out letter by letter. Guests point their phone camera at the code and join your network instantly — no typing, no mistakes, no shouting "capital S, then 4, then exclamation mark" across the room. It works for homes, Airbnbs, cafés, offices, and anywhere else visitors ask for the password.

This guide covers the full workflow: how to find your Wi-Fi password on any device, the built-in sharing options on Android and iPhone (and where they fall short), and how to generate a printable qr code for wifi password sharing in about 30 seconds — free, no signup, no app install.

Step 1: Find your Wi-Fi password first

You can't make a code without the password itself. Where it lives depends on your device:

• iPhone (iOS 16 or later): Settings → Wi-Fi → tap the (i) next to the connected network → tap the Password field and authenticate with Face ID. On iOS 18, the Passwords app lists every saved network under its Wi-Fi section. Apple's own guide to recovering a lost Wi-Fi password walks through each option.
• Android: Settings → Network & internet → Internet → tap the connected network. Some versions show the password on the share screen; if yours doesn't, the router is your fallback.
• Windows: Settings → Network & internet → Wi-Fi → click the connected network name to reveal its properties, including the password.
• Mac: Open Keychain Access, search the network name, open it and tick "Show password."
• Router: The default password is usually on a sticker underneath the router; if it was changed, log in to the router's admin page to view or reset it.

Step 2: Try your phone's built-in sharing

On Android, sharing is genuinely one tap: Settings → Network & internet → Internet → tap your network → Share → authenticate, and a QR code appears that any phone camera can scan. Google documents the exact flow in its official Wi-Fi sharing instructions. The guest doesn't need an Android phone — any modern camera app reads the code.

On iPhone, it's more limited. Apple's sharing only works Apple-to-Apple: both devices unlocked and nearby, both signed in to Apple Accounts, the guest in your contacts, Bluetooth on. When the guest selects your network, a "Share Password" notification pops up on your phone — see Apple's guide to sharing a Wi-Fi password. There's no native way to print a code or share cleanly with Android guests, which is where a generated code wins.

Step 3: Generate a universal code in 30 seconds

When native sharing falls short — mixed iPhone and Android households, printed cards, Airbnb welcome books — a generated WiFi QR code works everywhere, for everyone, with zero setup on the guest's side.

1. Open the free QR code generator and switch to the Wi-Fi tab.
2. Enter the network name (SSID), the password, and the security type (usually WPA/WPA2). Tick "hidden network" if your router doesn't broadcast its name.
3. Download the PNG, or hit Print on the Wi-Fi tab of FrostRank's QR generator for a ready-to-cut guest card with the network name and password printed beneath the code — handy for visitors whose cameras won't scan.

Everything runs in your browser, so the password never leaves your device. The code embeds the credentials directly, which means it keeps working forever with no account, no subscription, and no third-party server involved.

Which method should you use?

Where to put the code (and one smarter move)

A printed code earns its keep on the fridge, in the entryway, on a café counter, or inside an Airbnb welcome book — anywhere guests naturally look when they arrive. Pair it with a short line like "Scan to join Wi-Fi" so nobody has to guess what it's for.

The smarter move: most routers can broadcast a separate guest network. Put visitors on that instead of your main network, and point the QR code at the guest credentials. Guests get online in one scan, and your laptops, NAS, and smart-home gadgets stay on a network they can't see.

A quick word on security

A WiFi QR code contains your actual password in plain text — anyone who scans it can extract it, so treat the printed code with the same care as the password itself. That's another reason the guest-network trick above is worth the two minutes it takes to set up. For the deeper tradeoffs (including why static codes beat account-based ones for anything printed), see the complete QR codes guide.

Frequently asked questions

How do guests scan a WiFi QR code?
They open their phone's camera app, point it at the code, and tap the "join network" prompt that appears. No extra app is needed on any modern phone.

Can I create a WiFi QR code on iPhone without installing an app?
Yes. On iOS 18 the Passwords app can display a QR code for a saved network, and otherwise you can generate one in Safari with the free tool above — nothing to install.

What happens if I change my Wi-Fi password?
The old code stops working immediately, because the password is baked into it. Generate a fresh one — it takes about 30 seconds — and replace the printout.

Does it work with hidden networks?
Yes. Tick the "hidden network" option when generating so the scanning phone knows to look for a network name that isn't being broadcast.

Is sharing Wi-Fi with a QR code safe?
The format itself is safe, but the password sits inside the code in plain text. Anyone holding the printout can read it, so use a guest network for visitors and don't post the code publicly.

Do I need to be connected to the network to make the code?
No. You only need the network name and password — you can generate a code for your home Wi-Fi while sitting in a café.
