Dynamic WiFi QR codes

A WiFi QR that scans to a page you control — change the password whenever, the printed sticker keeps working.

Updated today 4 min read

A WiFi QR built here scans to a page on your subdomain — not the standard WIFI: string baked into the modules. When the password rotates, you change it from your dashboard and every existing sticker, table card and poster keeps working.

The password changes. The QR doesn't. Same printed code, new password, no reprint. Pick one of the three themes and you're done.

What you can do

Create a WiFi link Network name, password, page copy, theme. One form. Rotate the password Change it in the dashboard — the printed QR keeps working. Theme the page Light, dark, or mint. Title + subtitle of your choice. Hide "Powered by" Lifetime + hosting plans can turn the footer off in Settings.

Create a WiFi link

  1. Pick the WiFi destination type. The form swaps to network + password + page-copy fields.

  2. Network name (SSID).

    Exactly as it appears on the router or in the WiFi list on a connected device.

  3. Password.

    Type or paste it. The page shows the password to anyone who scans — copy it from the device that's already connected, or grab it off the router sticker.

  4. Page title + subtitle (optional).

    Title shows up under the WiFi mark — "WiFi at Mountain Café" or similar. Subtitle is one or two lines of welcome copy.

  5. Pick a theme.

    Light, dark, or mint. The tiles in the form show what each looks like.

What guests see

A scan opens the page with three things stacked: the network name in a row, the password in the next row, and a Copy button next to each. One tap and the value goes to clipboard — the guest doesn't need to read it off the screen or type it character by character.

The Copy button is the point. On a coffee-shop counter sign, retyping a long password off a small phone screen breaks half of guests. Tap Copy, tap into the WiFi password field, paste. Done.

Rotate the password

  1. Same row as every other short link — click it to open the editor.

  2. Update the password field.

    The page picks up the new value on the next scan. No new QR, no reprint, no re-stickering.

  3. Save.

    Autosave fires on blur. The next guest scan reads the new password.

Theme the page

Three themes ship today. Light is the default. Dark suits late-night venues — bars, lounges, hotels. Mint matches the platform's brand accent for anyone who wants to lean into it.

The picker is a visual tile in the WiFi destination form — each tile shows the theme's palette, click to set. Theme applies on the next scan; existing scans don't need a reprint either.

Hide "Powered by" footer

The WiFi page reads its "Powered by Linked.Codes" footer from the same toggle that controls every other public surface — Settings → Branding → Show "Powered by" footer.

  • Free tier: footer always shown.
  • Lifetime + hosting tiers: toggle in Settings hides it across every WiFi page, every short-link-domain landing, every public surface in one go.

Use cases

  • Hotels — rotate the password per stay, refresh check-in cards once, ride them for months.
  • Airbnbs + short-term rentals — one sticker per property. Cycle the password between guests without printing new welcome books.
  • Cafés + restaurants — table-top QR survives staff turnover. The next password swap doesn't mean reprinting menus.
  • Salons, gyms, co-working — guest network on a single counter QR. Staff rotates the password monthly; no comms required.
  • Event venues + conferences — sponsor-branded WiFi page that updates per event. The same printed QR works through the season.

Limitations

WPA networks only right now. Open networks (no password) and WEP-encrypted networks aren't exposed in the form — the page assumes there's a password to copy. If your network is open, point a regular short link at your captive-portal URL instead.
  • The page is shown after a scan via the browser. Phones don't "auto-join" the network like the static WIFI: string does — the trade-off is that the printed QR survives password changes forever.
  • The browser preview shows your subdomain in the URL bar before the page loads. Set up a custom short-link domain so the preview reads as your brand instead of the platform default.
