生成您的 WiFi 二维码
QR design & error correction options
🔒 100% Client-Side Privacy: Your WiFi SSID and password are processed directly in your browser using local cryptographic functions. Credentials are never sent over the network.
Beyond static QR codes: captive portals & private PSKs
Shared QR codes leak passwords and lack compliance. Purple delivers branded captive portals, automated CRM capture, and per-tenant private PSK (iPSK) on Cisco Meraki, Aruba, Ruckus, and UniFi.

WiFi 二维码将网络名称、安全类型和密码编码为 iOS 和 Android 相机可原生读取的格式。访客只需将相机对准二维码并点击即可加入，无需口述或手动输入密码。您可以将其打印并放置在接待台、酒店客房、会议室或咖啡厅桌面。
此工具为您提供
- 支持 WPA/WPA2/WPA3、WEP 和开放网络，以及隐藏的 SSID。
- 提供清晰的 SVG 和高分辨率 PNG 下载，适合任何尺寸的打印。
- 完全在客户端运行。您的网络名称和密码绝不会离开浏览器。
WiFi QR code syntax and URI specification
Modern smartphone cameras (iOS 11+ and Android 10+) parse wireless network configurations using the standardized MeCard / ZXing wireless URI scheme. Each parameter in the string is separated by a semicolon and terminated with a double semicolon.
| Parameter | Field Name | Syntax & Examples | Description |
|---|---|---|---|
| WIFI: | Scheme Header | WIFI:... | Declares the barcode payload as a wireless network configuration string. |
| S: | Network SSID | S:MyNetwork; | The service set identifier (network name) broadcast by the access point. |
| T: | Authentication Type | T:WPA; | T:WEP; | T:nopass; | Encryption protocol: WPA (covers WPA/WPA2/WPA3-Personal), WEP, or nopass for open. |
| P: | Pre-Shared Key | P:SecretPassphrase; | Network passphrase or security key. Special characters (;, :, \, ") must be backslash-escaped. |
| H: | Hidden Network Flag | H:true; | H:false; | Optional boolean flag indicating whether the SSID is hidden and does not broadcast beacons. |
| ;; | Payload Terminator | ;; | Double semicolon terminating the wireless configuration record. |
Static WiFi QR codes vs enterprise captive portals vs iPSK
Choosing the right onboarding method depends on your venue size, security requirements, and visitor engagement goals. Compare how static QR codes stack up against managed captive portals and dynamic Identity Pre-Shared Keys (iPSK).
| Feature | Static QR Code | Purple Captive Portal | Identity PSK (iPSK) |
|---|---|---|---|
| Primary use case | Small cafes, home offices, private meeting rooms | Public venues, retail, hospitality, healthcare, events | Student housing, build-to-rent (BTR), multi-tenant units |
| Authentication method | Shared pre-shared key (PSK) | Web login, SMS OTP, social auth, or email verification | Unique dynamic pre-shared key per user or apartment |
| Password security | Shared password easily leaked or forwarded | No shared password; dynamic session authorization | Private key isolated to specific resident devices |
| Client device isolation | Requires manual AP client isolation configuration | Built-in network isolation and firewall ACLs | Dynamic VLAN/micro-segmentation per resident |
| Visitor insights & CRM data | Zero data capture or visitor analytics | Real-time footfall, dwell time, CRM sync (HubSpot, Salesforce) | Resident device mapping and bandwidth management |
| Regulatory compliance | No terms of service or GDPR/CCPA acceptance | Automated legal compliance, opt-in consent, and audit logs | Tenant privacy compliance and audit readiness |

常见问题解答
WiFi 二维码在 iPhone、iPad 和 Android 上是如何工作的？
当移动设备相机扫描符合标准无线网络 URI 方案（WiFi:S:SSID;T:WPA;P:password;;）格式的 WiFi 二维码时，操作系统会直接解析网络凭据。iOS 和 Android 会显示原生通知提示，询问用户是否要加入该网络。点击提示后，设备将自动关联网络，无需手动选择 SSID 或输入密码。
使用此工具在线生成 WiFi 二维码安全吗？
安全。此工具完全在客户端运行，使用您网页浏览器中的 JavaScript。您的网络 SSID、安全加密类型和预共享密码绝不会传输到我们的服务器，也不会存储在任何数据库中。SVG 和 PNG 图像均在您的设备上本地生成。
支持哪些 WiFi 安全加密类型？
此工具支持 WPA、WPA2 和 WPA3-Personal (SAE/PSK) 网络、传统的 WEP 网络以及开放式未加密网络 (nopass)。它还支持隐藏网络广播标志。
我可以为隐藏的 SSID 生成二维码吗？
可以。启用“隐藏网络”选项会在二维码负载中包含 H:true 参数。扫描时，支持的客户端设备将在网络关联期间专门探测隐藏的 SSID。
为什么商业场所要从静态二维码升级为 Purple 强制门户？
虽然打印的二维码对小型办公室很方便，但大型公共场所、酒店和零售品牌在面对共享密码时会遇到安全和运营方面的挑战（例如带宽滥用和无法获取访客洞察）。Purple 用品牌化的强制门户、自动化的 CRM 潜在客户获取、GDPR/CCPA 合规性以及 802.1X 私有 PSK (iPSK) 身份验证取代了静态凭据。
Running guest WiFi at scale?
A printed QR code is the easy bit. Purple adds branded captive portals, data capture, and analytics on top, so guest WiFi becomes a marketing channel across every venue.
