The platform, which has billions of users worldwide, said the decision was taken with user safety in mind, particularly for younger audiences. Company representatives indicated that fully encrypted messaging could limit the ability of authorities to access communications when investigating harmful or illegal activity.

Under E2EE systems, only the sender and recipient can read the contents of messages, preventing access by hackers, corporations or government bodies. The approach is widely viewed as a key safeguard for digital privacy.

Several major messaging services have already adopted E2EE, including WhatsApp, Signal, Facebook Messenger and iMessage.

According to information shared with BBC, TikTok acknowledged that full encryption would prevent law enforcement and security agencies from accessing private messages, potentially increasing risks related to harassment and grooming.

Industry analyst Matt Navarra argued that failing to implement E2EE could put TikTok at odds with evolving international privacy standards. The company has previously faced scrutiny over data protection practices and alleged links to the Chinese government.

Other platforms handle encryption differently. Signal, WhatsApp, Facebook Messenger and iMessage use E2EE as a default setting. Instagram is in the process of enabling it by default for direct messages. X offers encrypted messaging, while Telegram provides E2EE as an optional feature. Snapchat applies encryption to photo and video messages and plans to extend it to text chats. Discord has announced that voice and video calls will use E2EE by default.

TikTok’s stance has renewed debate over how social media companies should balance privacy protections with safety and regulatory obligations, particularly given the platform’s large base of young users.
