WhatsApp QR Code Login Security Analysis
According to foreign media reports, WhatsApp has started supporting QR code functionality in iOS and Android Beta versions. This feature, developed over a year, offers fully encrypted conversation protection.
功能特点与安全措施
用户可以生成并与好友共享二维码，对方扫描即可加入聊天。WhatsApp在相机应用中添加了特殊扫描功能。如果二维码泄露，用户可立即注销并创建新码。理想情况下，二维码应仅由个人共享以避免风险。
Features and Security Measures
Users can generate and share QR codes with friends, who can scan to join chats. WhatsApp has added special scanning features in its camera app. If a QR code is compromised, users can immediately revoke it and create a new one. Ideally, QR codes should only be shared personally to avoid risks.
隐私限制与版本信息
外媒WABetaInfo指出，二维码并非完全私密，因其包含电话号码。因此，虽可用于私人通信，但无法实现匿名。该功能存在于WhatsApp Beta v2.20.171中，可通过“设置”菜单的“配置文件”部分访问。
Privacy Limitations and Version Information
WABetaInfo notes that QR codes are not entirely private as they contain phone numbers. Thus, while usable for private communication, anonymity cannot be achieved. This feature is available in WhatsApp Beta v2.20.171 and accessible via the "Profile" section in the "Settings" menu.
