慢雾余弦警告：建议桌面端Teleggram用户开启Passcode Lock功能并记牢对应密码

Odaily Odaily reported that Cosine, founder of SlowMist, posted on platform X, recommending that users of the desktop version of Telegram enable Passcode Lock and remember their set passcode (forgetting it requires re-logging into Telegram).

It is understood that this passcode is mainly used to unlock the user's local Telegram session, allowing access to highly sensitive local data (such as identity-related information). Enabling this application lock helps protect local data, preventing unauthorized access to the device or account theft/compromise via malware.
