How a Wi-Fi QR code works
The code holds your network name, password and security type in a standard format that the iPhone and Android cameras understand. Scanning it shows a "Join network" button. Your password is drawn into the code on this device and is never sent anywhere.
Find the network name and password on the sticker under your router. If you change the password, make a new code.
Questions
Will these QR codes expire?
No. Keeper makes static codes: your link, Wi-Fi details or contact card are stored in the pattern itself, so there is no server in the middle that can be switched off. A link code works for as long as the page it points to is online.
Why did my old QR code stop working?
Most likely it was a dynamic code. Many generators put their own short link in the code and redirect it to yours, then turn the redirect off when a free trial ends. Use the checker on this page to see where a printed code really goes.
Is it free? Do I need an account?
Free, no account, no watermark, no scan tracking. The code is drawn in your browser and nothing you type is sent to us.
How big should I print it?
At least 2 cm (about 0.8 in) across for something held in the hand, like a business card. For a poster read from a distance, divide the distance by ten: scanned from 2 metres, make it 20 cm.
Can I change the colour?
Yes, pick any of the dark inks. Keeper only offers colours dark enough on white for phones to read reliably. Light codes on dark backgrounds fail on some phones, so they are not offered.
Can I change where it points after printing?
Not with a static code, and that is the trade. If you want to change the destination later, point the code at a page you own, like your own website, and change that page instead.
