How2 Android: Share Wi-Fi With a QR Code
Your Wi-Fi password is sixteen characters of chaos, and a guest is waiting. Your Android phone already hides a QR code that shares it in one scan. No spelling, no shouting, no typos.
The Step-by-Step: Show Your Wi-Fi QR Code
Open Settings, then Network and Internet, then Internet. Tap the Wi-Fi network you are connected to, then tap Share. Your phone asks you to confirm it is you with your fingerprint, face, or PIN, because this screen reveals the password in plain text under the code.
Show the QR code to your guest. On their phone, they open the camera or Wi-Fi settings and scan. Most modern phones offer to join the network the moment the code is recognized. That is the whole spell: Settings, Internet, tap your network, Share, scan.
- Settings → Network and Internet → Internet
- Tap your connected network → Share
- Confirm with fingerprint or PIN, then let them scan
Helping iPhone Guests and Older Phones
An iPhone scans the same code from its Camera app or from Control Center's QR control and offers to join. The code is a standard format, so it works across brands. The password also appears as text under the code on many Android phones, which saves guests whose camera is cracked or ancient.
If a guest's phone is too old to scan codes, read them the plain-text password from that same screen. It beats digging through your router settings or hunting for the sticker you meant to photograph years ago.
| Option | Best for | Watch out |
|---|---|---|
| QR scan | Fastest, no typos | Very old phones may not scan |
| Plain text on Share screen | Always works | Anyone viewing can read it |
| Router sticker password | Last resort | Often changed long ago |
The Safety Rules Nobody Mentions
Anyone who can see that QR code can join your network forever, including a photo of it. Do not post the code anywhere, and do not keep a screenshot of it in your camera roll where a shared album might spread it further.
If a crowd of guests just passed through, like after a party or a rental weekend, change the Wi-Fi password afterward or move guests onto a guest network next time. Most routers offer a guest network in their settings, and it keeps visitors away from your computers and smart home gear.
- Never post or store the QR code photo
- Use a guest network for parties and visitors
- Change the password after big gatherings if you shared the main one
Bonus: Print a Guest Code for the Fridge
Frequent hosts can print the QR code once and frame it by the door. Many routers and free QR generators can make a Wi-Fi code from your guest network details, which is the one worth printing because it is separated from your main devices.
Keep the printed code on the guest network only. When you eventually change the guest password, reprint the little card. Guests get online in seconds, your main password stays private, and nobody ever has to spell anything across the kitchen again.
