However, users can report messages to the company. With end-to-end encryption enabled by default, Meta says it won't be possible for the company to read users' messages. When your chats are upgraded, you will be prompted to set up a recovery method, such as a PIN, so you can restore your messages if you lose, change, or add a device,' Crisan wrote. It will take a number of months to complete the global roll-out. 'Because we have over a billion users, not everyone will get default end-to-end encryption right away. Meta also previously implemented E2EE on millions of accounts while testing the feature.

Meta said it will take months to implement across its entire user base. This has taken years to deliver because we've taken our time to get this right,' Crisan wrote yesterday. 'Since 2016, Messenger has had the option for people to turn on end-to-end encryption, but we're now changing personal chats and calls across Messenger to be end-to-end encrypted by default. Meta said it is using 'the Signal Protocol, and our own novel Labyrinth Protocol,' and the company published two technical papers that describe its implementation. Meta also plans default end-to-end encryption for Instagram messages but has previously said that may not happen this year.ĬEO Mark Zuckerberg said in 2019 that the company planned to 'implement end-to-end encryption across all of our messaging services.' The Meta-owned WhatsApp already had end-to-end encryption enabled by default, and users could enable the security technology on Messenger. Meta held firm, telling Ars in April that 'we don't think people want us reading their private messages' and that the plan to make end-to-end encryption the default in Facebook Messenger would be completed before the end of 2023. The consortium complained that terrorists, sex traffickers, child abusers, and other criminals will use encrypted messages to evade law enforcement. In April, a consortium of 15 law enforcement agencies from around the world, including the FBI and ICE Homeland Security Investigations, urged Meta to cancel its plan to expand the use of end-to-end encryption. 'Today I'm delighted to announce that we are rolling out default end-to-end encryption for personal messages and calls on Messenger and Facebook,' Meta VP of Messenger Loredana Crisan wrote yesterday. Meta has started enabling end-to-end encryption (E2EE) by default for chats and calls on Messenger and Facebook despite protests from the FBI and other law enforcement agencies that oppose the widespread use of encryption technology.
