How to Share Your Wi-Fi Password With a QR Code on Android
Spelling "capital S, lowercase seven, underscore" across the room never works the first time. A Wi-Fi QR code connects a guest in two seconds and keeps the password out of the conversation.

On Android 10 and later, open Settings > Wi-Fi, tap your connected network and then Share. After unlocking, Android shows a QR code that any phone camera can scan to join. It is handy, but it is four taps deep, and there is no way to keep it visible or print it.
Keep the Wi-Fi code one tap away
With QR Actions you can create a Wi-Fi QR code once, style it, and pin it to the home screen as a widget. Guests scan it from your phone while you keep talking. The network name and password are stored only on your device.
- Open QR Actions, tap Create and choose Wi-Fi.
- Enter the network name, the password and the security type (usually WPA/WPA2).
- Save it and add it to the home screen, or share the image to print it.
A printed code for your home, café or clinic
Share the generated image to a printer or a messaging app, print it at a readable size, and put it where guests sit. Add a line such as "Scan to join Wi-Fi" so people know what it is. Because the code is generated on the device, it keeps working for as long as the password stays the same; change the password and simply make a new code.
Security notes
A Wi-Fi QR code contains the password in plain form, so treat the printed version like a written password: fine on a wall in your home or shop, not something to post online. If you offer Wi-Fi to the public, use a separate guest network so visitors cannot reach your own devices.
Frequently asked questions
Which phones can scan a Wi-Fi QR code?
Any recent Android phone or iPhone with the camera app; both recognise Wi-Fi codes and offer to join the network.
Does it work for 5 GHz networks?
Yes. The code carries the network name and password; the phone picks the band.
Can I hide the password from guests?
The code contains it, but a guest scanning it never has to see or type it, which is still far better than reading it out.
