Meta rolls out encrypted messaging by default for Facebook and Messenger

Users of Meta’s Facebook and Messenger apps will now have their messages protected by end-to-end encryption, according to a statement from the company. The decision is expected to enhance security and privacy for users, but some governments may oppose it due to concerns that encrypted messages could aid criminal activity. Meta had previously announced plans to make encrypted messaging the default mode for its platforms, with WhatsApp already offering encrypted communications since 2016. Messenger also introduced optional end-to-end encryption in the same year. This new rollout required a significant redesign of Messenger to support default encryption. The update brings Facebook and Messenger in line with WhatsApp and other rival apps that offer similar levels of protection, such as Signal and Apple’s iMessage. Under the new default settings, even Meta will not have access to user messages. However, when participants report a message, it may be visible to Meta. The expansion of end-to-end encryption is seen as a positive development for individuals such as political dissidents, human rights workers, journalists, and minorities who rely on encryption for protection against authoritarian governments. On the other hand, law enforcement officials have expressed concerns that increased privacy measures could hinder investigations. In 2019, Meta clashed with the US Justice Department over encryption, with the company arguing that weakening encryption would benefit criminals and repressive regimes. UK officials have also criticized Meta’s plan, claiming that it could assist child sex abusers and hinder law enforcement’s ability to prosecute offenders. Both law enforcement agencies and tech companies have been at odds over the issue of providing authorized access to encrypted messaging without compromising security.
