Facebook Introduces New Features for End-to-End Encrypted Messenger App

Meta Platforms on Monday announced that it has started to expand
global testing of end-to-end encryption (E2EE^[1]) in Messenger chats by
default.

“Over the next few months, more people will continue to see some
of their chats gradually being upgraded with an extra layer of
protection provided by end-to-end encryption,” Meta’s Melissa
Miranda said^[2].

The social media behemoth said it intends to notify users in
select individual chat threads as the security feature is enabled,
while emphasizing that the process of choosing and upgrading the
conversations to support E2EE is random.

“It’s designed to be random so that there isn’t a negative
impact on our infrastructure and people’s chat experience,” Miranda
further explained.

Along with flipping the switch on E2EE, Meta has also added more
features into its encrypted chat experience, including support for
themes, custom emojis and reactions, group profile photos, link
previews, and active status.

The latest development comes a little over five months after it
officially began testing^[3] the feature as a default
in August 2022. It’s, however, worth noting that E2EE was enabled^[4]
as an opt-in nearly seven years ago in the form of “secret conversations^[5].”

In comparison, WhatsApp already has E2EE enabled out of the box,
and Instagram lets users switch on E2EE^[6]
for individual conversations^[7].

The security setting is also part of Meta’s broader “privacy-focused vision for social
networking^[8],” which it hopes to roll
out across Messenger and Instagram at some point this year after
taking additional time to “get this right^[9].”

The move further arrives amid a broader push by tech giants to
incorporate encryption options in their services. Google, last
month, introduced^[10] E2EE for group chats
with as many as 100 users in its RCS-based Messages app^[11] for Android. The
feature is currently limited to the beta version.

Apple, in a similar move, has unveiled^[12] an Advanced Data
Protection option for iOS, iPadOS, and macOS that enables
end-to-end encrypted (E2EE) data backups in its iCloud service. An
encrypted chat feature for Twitter direct messages is presently
in the works^[13].
