[SlowMist Founder Yu Jian Warning: Desktop Telegram Users Advised to Enable Passcode Lock and Remember the Corresponding Password] Odaily Planet Daily News – SlowMist Technology founder Yu Jian posted on the X platform, recommending that users of the desktop version of Telegram enable the Passcode Lock feature and remember the set passcode (if forgotten, Telegram will need to be re-logged in). It is understood that this passcode is primarily used to unlock the local use of Telegram, granting access to sensitive local data (e.g., identity-related information). Setting up an app lock helps protect local data, preventing unauthorized physical access to the device or theft/account takeover due to malware.
