WiFi QR Code Generator — Scan to Connect, Password Stays Private

Real-world use cases

• Cafe guest WiFi card on the counter

  Stop answering "what's the password?" forty times a shift. Fill SSID + password, pick "WPA / WPA2 / WPA3", leave "hidden" unchecked. Set size to 512 px, error-correction M, export PNG (or hit "Print poster" for the ready-made sheet). Print at A6, laminate, and place it within arm's reach of where customers actually sit — phones lock between the counter and the table. Test by scanning from 40 cm before you laminate. Keep it black-on-white; a colored background drops the scan rate noticeably even when contrast looks fine on screen.

• Airbnb / vacation rental welcome sheet

  Guests arrive, scan, connected — before they've even put the bags down. Use the rental's guest network SSID and password, encryption "WPA / WPA2 / WPA3". Export SVG so the same QR scales cleanly onto a framed A5 welcome card next to the check-in instructions. Step by step: type the network name exactly as it appears on the router label (case-sensitive), paste the password (special characters are escaped automatically), set error-correction Q so a smudge on a well-handled card still scans, download SVG, drop it into your welcome-sheet template. Reprint only when you rotate the password.

• Office visitor network at reception

  Visitors join the guest VLAN without IT tickets or front-desk spelling. Fill the guest SSID + rotating password, pick WPA, and if the guest network is intentionally not broadcast, tick "hidden network" so the payload includes `H:true` and phones search for it. Export PNG at 384 px for a reception-desk acrylic stand. Step by step: confirm the encryption with IT (WPA2/WPA3 personal → "WPA"), generate, and reprint on the day the password rotates. Because the password never enters the URL or storage, you can generate it on a shared reception machine without leaving it in the browser history.

• Pop-up event or market stall WiFi

  Vendors and staff at a weekend market need the back-of-house network fast. Generate a WiFi QR, print a few copies on plain paper, tape one to each till. Use error-correction H here — paper taped to a metal stand gets crumpled and rained on, and H recovers up to ~30% damage. Step by step: SSID + password + WPA, error-correction H, size 256 px (small footprint, still scans at arm's length on H), PNG, print on the office laser, done. No app, no account, no cloud round-trip.

• Replace a sticky note with a scannable code for relatives

  The fridge sticky note with the WiFi password in fading marker is a security and legibility mess. Generate a clean QR instead: SSID + password + WPA, size 384 px, PNG. Print one, magnet it to the fridge. Relatives and houseguests scan instead of squinting. Step by step: read the SSID off the router (not the network you renamed in the app, unless they match), paste the real password, generate, print. When you change the password, regenerate in ten seconds — the old printout just stops working, which is the point.

Common pitfalls

• Choosing the wrong encryption type. WPA, WPA2 and WPA3 personal all use the single "WPA" QR type code — there is no "WPA3" option and you don't need one. The mistakes that actually break joins are leaving a password on a "None / open" network, or selecting WEP for a modern WPA router. Match the router, and when in doubt for a home/office router pick "WPA / WPA2 / WPA3".

• Hand-escaping a password that contains special characters. People see that `;` and `:` are reserved and start adding their own backslashes, then this tool escapes again, and the doubled backslashes get into the real password. Paste the raw password exactly as your router has it — the escaping is done for you, once, automatically.

• Printing too small or on a colored background. Under ~3 cm square, or white modules on a tinted card, real-world scan distance collapses to almost touching the paper. Print black-on-white at 3 cm or larger, and scan-test from arm's length before you laminate or frame it.
