Wi-Fi QR code: native join, or a password you can change

Phones already know how to join from a QR

The usual payload is a WIFI: string — network name, security type, and password — documented in the ZXing barcode contents guide. iPhone and iPad Camera (and Android) can scan it and prompt Join. Apple’s Passwords app can show the same kind of network QR. Use those if this exact network stays put.

On qrcode.house the Wi-Fi type writes WPA/WPA2, WEP, or an open network into the file. That is a static download. A free URL download is different: it is already a short link, first destination frozen, until you unlock. Billing is about whether you can retarget a door after print — not about storing SSIDs.

Free is enough when the password is stable

Many “always buy dynamic” guides skip this. If guests should always join the same network, a free Wi-Fi file, a router sticker, or Adobe Express all work. No unlock required.

• The guest password rarely changes

  A café, studio, or home network that keeps the same SSID and passphrase can use a free Wi-Fi file. The pattern already holds the join string. Adobe Express and a router’s own sticker work the same way.

• You want the phone to join, not open a browser

  A WIFI: payload is the point. Camera apps prompt Join. A URL to a password note is a worse guest experience if you will never rotate the key.

• The print is cheap to replace

  A same-week table card, a slide, or an Airbnb binder page can stay free. Reprinting is cheap when the paper is thrown away.

Unlock a URL code when the sticker must outlast the password

After unlock, a scan hits a short link on qrcode.house and we load whatever URL you last saved. Host the actual password on your own page — a /wifi note, an intranet post, a rental welcome doc. That is the product: a retargetable door, not a captive portal. Flow: how dynamic QR works.

• The wall sticker has to outlast a password rotation

  Offices, rentals, and venues that rotate guest Wi-Fi should not bake the current key into vinyl. Point a URL code at a page you host with today’s password, then unlock $9.99/year to retarget that page.

• You share one print for Wi-Fi and something else later

  A counter card that is the network this season and a menu, review, or closed notice next season is a destination edit — not a new print run. That is a URL code, not the Wi-Fi type.

• The file host will mint a new address

  A replaced Notion page, a new Drive doc, or a renamed /wifi path is a new URL. A frozen join QR cannot follow it. Unlock stores the short link on your account.

One unlocked code can cover the room

If every table tent should open the same password page, print the same file. That is one destination and — if you unlock — one $9.99/year code, not a code per sticker. Keep the menu QR as a second print when the dining-room link is different. Bitly and QR Code Generator typically sell a monthly platform plan for a pool of dynamic codes and campaign tools. A single guest network that needs one lasting sticker is the per-code case — when that model wins is on dynamic QR price vs monthly SaaS. The two live prices are on the pricing page.

Treat a Wi-Fi QR as a public password

Encoding the key in the pattern is convenient. It is not a vault. The longer safety guide is is this QR code safe.

• Put guests on a guest SSID. Do not print the staff, POS, or admin network.
• Assume anyone who can see or photograph the sticker can join. Rotate if that is no longer acceptable — and reprint a Wi-Fi-type file, or edit the URL behind an unlocked code.
• Print the network name next to the code so people can check the Camera preview before they join.

What we do not do

• We do not store Wi-Fi passwords, run a captive portal, or manage your router. The Wi-Fi type lives in the downloaded file.
• We do not encode hidden SSIDs or enterprise EAP in the builder. Use WPA/WPA2, WEP, or open.
• Custom centre logos ship with a dynamic unlock; free downloads use the QRcode.house logo.

FAQ

Can I make a free Wi-Fi QR code?

Yes. Choose Wi-Fi on qrcode.house, enter the network name, security (WPA/WPA2, WEP, or open), and password, then download PNG, JPEG, SVG, or PDF with no account. The file encodes a WIFI: string in the pattern. Free files include the QRcode.house centre mark.

Is a Wi-Fi-type QR dynamic?

No. The Wi-Fi type bakes the SSID and password into the modules, the same model as Adobe Express, most router stickers, and the QR in Apple’s Passwords app. Change the passphrase and that printed file is wrong. We do not store Wi-Fi passwords for later editing.

When should I unlock $9.99/year for guest Wi-Fi?

When the physical sticker must stay on the wall after the password moves. Do not unlock the Wi-Fi type expecting us to rewrite the join string. Create a URL code to a page you already host that lists the current password, then unlock that URL. Codes you never unlock stay free downloads.

Does the QR contain the Wi-Fi password?

Yes, if you use the Wi-Fi type. Anyone who photographs the sticker can read the payload. Use a guest network, not the staff or admin SSID. A URL to a password page has the same problem if that page is public — treat it as a convenience, not a secret.
