Why does the desktop version require phone QR code login?

扫码登录为桌面端增加一道安全校验，只有已登录的手机才能授权电脑端上线，可有效防止账号被他人冒用与异地登录。

消息是否端到端加密？服务器能看到吗？

Are messages end-to-end encrypted? Can the server see them?

所有消息在发出前即完成加密，传输与存储全程为密文，只有收件人能够解密查看，服务器与任何中间环节都无法获知内容。

Messages are encrypted before they leave your device, stay encrypted in transit and storage, and only the recipient can decrypt them — servers and intermediaries can't read them.
