WiFi Fields Snapkit Actually Encodes

The Snapkit homepage has a WiFi tab, not a “paste any WIFI: string” box. You fill four controls. The browser builds one payload and draws a static PNG. If you expect WPA3 as a fourth option, a Dynamic checkbox, or scan analytics on a guest sign, the form will not invent them.

This page is the field list as implemented. It is not a rewrite of the generic guest Wi‑Fi guide—that article is the WIFI: format, placement, and “stop spelling the password” walkthrough. How the canvas and PNG work is a separate page.

Field → payload

Download and preview are valid when Network Name (SSID) is non-empty after trim. Password, encryption, and Hidden do not gate the button.

Form label	Control	Encoded as	Notes
Network Name (SSID)	text, id qr-wifi-ssid, placeholder MyWiFiNetwork	S:{ssid}	Required. Typed as-is. Case-sensitive, like the AP.
Password	password, id qr-wifi-password, placeholder Enter WiFi password	P:{password}	Optional. Empty string is allowed. Always present as P:, even under No Password.
Encryption Type	select, id qr-wifi-encryption	T:{value}	Default WPA. Empty value also falls back to WPA.
Hidden Network	checkbox, id qr-wifi-hidden	H:true; only when checked	Stores "true" / "false". Unchecked adds nothing (H:false is not written).

Wrapper is always:

WIFI:T:{encryption};S:{ssid};P:{password};{optional H:true;};

Visible network, WPA, password secret:

WIFI:T:WPA;S:CafeGuest;P:secret;;

Same network, Hidden on:

WIFI:T:WPA;S:CafeGuest;P:secret;H:true;;

Generation is in the browser. The string is not uploaded. There is no account requirement for a default static PNG. The print is still public: anyone who photographs or decodes the PNG reads the password. Treat a guest-network sign the way you would treat the password taped to the wall.

Encryption options

The select has three rows. There is no WPA3 option. If the access point is WPA2 or WPA3-personal, the value you send is still WPA—that is what the tab emits, and what most Camera join sheets expect.

Label in the form	Value in T:	When to use it
WPA/WPA2 (default)	WPA	Almost every password-protected home / café / guest SSID
WEP	WEP	Legacy hardware that still advertises WEP. Do not pick this to “be compatible.”
No Password	nopass	Open SSID. The password field stays on screen and is still written into P:.

Footgun: leave WPA/WPA2 selected and skip Password. Snapkit still downloads. The camera still offers Join. The AP rejects the empty PSK. The product does not pair-check encryption against the password box.

Second footgun: switch the select to No Password and leave leftover characters in Password. Those characters still land in P:. Clear the box if the network is open.

Enterprise 802.1X (username + password, certificates) and captive portals (hotel splash, room-number page) are out of scope for this tab. A WIFI: join sheet cannot fill those. Put a URL to the portal instructions in the URL tab, or keep the generic guest guide for the format background.

Hidden Network

Check Hidden Network only if the AP does not broadcast the SSID. The checkbox writes "true" or "false" in form state; the encoder adds H:true; only for "true".

Do not check it “just in case.” Phones then look for a non-broadcast name. If the network is visible in the picker, leave the box off.

No Dynamic, no analytics

The homepage checkbox Make this QR Code Dynamic (Editable) is shown only when the type is URL. WiFi has no Dynamic control and no scan-count product for this payload. A printed WIFI: string is the credentials. Rotate the guest password later and you reprint—or you stop using this tab and print a short URL you control.

Details: static vs dynamic and how Snapkit generates codes.

iPhone vs Android after a Snapkit WiFi scan

Modern Camera apps recognize a WIFI: payload and offer Join (iPhone) or Connect (Android). The user still confirms. Snapkit does not join the network for them.

Check	iPhone Camera	Android Camera / Lens
Valid WIFI: from this tab	Join sheet with the SSID	Connect prompt; OEM chrome differs
Hidden + H:true;	Usually still offered as that SSID	Pixel / Samsung / Lens disagree; test both
WPA selected, empty password	Sheet appears; join fails on a real WPA AP	Same
WIFI:… pasted into Text	Raw string. No Join sheet	Same — not this tab
802.1X / captive portal	Not a WIFI join	Not a WIFI join
Airplane / radio off	Sheet may appear; radio cannot associate	Same
Camera never locks	Size, contrast, crop — not “WiFi vs URL”	Same

If the camera never locks, start at QR code won’t scan and test the PNG. If it locks and still will not associate, that is SSID spelling, encryption, or a password you rotated—not a Snapkit scan bug.

Preview vs download

Preview is 256 px. Download is about 1024 px PNG. Do not screenshot the widget. Send the downloaded file to print or layout tools. Same rule as the other Snapkit product posts.

Special characters

SSID and password are inserted as typed. Snapkit does not escape ;, \, ", or :. Those characters are delimiters in the WIFI: grammar. A semicolon inside the PSK can make one phone parse a truncated password and another show the raw string.

If the guest network name or password has those characters, generate the PNG, then scan the file on an iPhone and an Android before you print a stack of table tents. Prefer a guest SSID that does not need escaping.

Common self-owns

What you did	What the scan does	Fix
Encryption set to WEP on a WPA2 AP	Join / Connect, then auth failure	Select WPA/WPA2 (T:WPA)
WPA selected, Password left empty	Download works; join fails	Type the real PSK, or switch to No Password only if the AP is open
; or \ in SSID / password	One brand joins, the other truncates or shows text	Test two phones; simplify the guest PSK if you can
WIFI:T:WPA;S:…;P:…;; pasted into Text	Raw string. No Join sheet	Use the WiFi tab
Screenshot of the 256 px preview	Soft modules after print	Download PNG (~1024 px)
Expecting Dynamic / analytics on WiFi	There is no checkbox	URL + Dynamic, or reprint when the password changes
802.1X office SSID in this tab	Join sheet cannot collect a username	Out of scope; this tab is PSK / open / WEP
No Password with leftover PSK text	T:nopass plus a non-empty P:	Clear Password when the network is open

Build list (this product)

1. Open snapkit.store. Choose WiFi.
2. Type the exact SSID. Type the password only if the AP has one.
3. Leave WPA/WPA2 unless the radio is actually WEP or open. Check Hidden Network only if the SSID is not broadcast.
4. Download PNG. Do not screenshot the 256 px box.
5. Scan the file on one iPhone and one Android. Confirm Join / Connect, then that the radio actually associates.
6. Print the human-readable SSID next to the mark. Prefer a guest network isolated from the LAN you care about.

This tab is the remaining homepage type that needed a field map. URL, Text, Contact, SMS, Email, and Phone already have theirs. Use the guest Wi‑Fi guide for placement and the WIFI: grammar; use this page when you need to know what the Snapkit form actually writes.
