Meta introduces end-to-end encryption by default on Facebook and Messenger

End-to-end encryption is now available for all calls and conversations conducted via the Messenger app and Facebook social media platform, according to a statement from Meta.

Clear data is safeguarded by end-to-end encryption (E2EE), which makes sure that only the parties engaged in the exchange may decrypt it. Information for everyone else who accessed it would be jumbled.

In order to ensure that data is safely transmitted over the internet in a format that cannot be deciphered by intermediaries, it encrypts the data on the sender’s device using a special encryption key.

The message’s receiver uses a private key that is exclusive to them to decode it locally on their device.

“Nobody, including Meta, can see what’s sent or said, unless you choose to report a message to us,” the business adds in its explanation.

To ensure availability across all user devices, Meta says that conversations and media transferred through Messenger will be kept in encrypted form on Meta’s servers. This information is provided in a separate article that provides further details on the underlying technology of the deployed E2EE method.
