Last week, Instagram ended its opt-in, and therefore rarely used, end-to-end encryption feature. Years after publicly promising to provide the privacy protections of end-to-end encryption across its platforms by default, it instead gave up on that technical challenge. Now, we've all lost an option for safer conversations on one of the biggest social media platforms in the world.

In an announcement in 2023, Meta bragged about how it had successfully encrypted Messenger, and teased that Instagram was in progress. Even before then, they’d talked about how important encryption was in Messenger and Instagram in a white paper published in 2022, stating: 

We want people to have a trusted private space that’s safe and secure, which is why we’re taking our time to thoughtfully build and implement e2ee by default across Messenger and Instagram DMs.

So where did the reversal come from? In a statement, Meta claimed that, “Very few people were opting in to end-to-end encrypted messaging in DMs.” This isn’t all that surprising, as turning it on was an optional four-step process that few people knew about. Defaults matter, and Meta’s choice to blame people for failing to opt into this feature is proof of how much. In that same statement, the company pointed people to WhatsApp for access to encrypted messaging. Yet if Meta truly wanted people to have a trusted private space to communicate, it would meet them everywhere they are: on WhatsApp, on Messenger, and on Instagram.

But at least Meta was straightforward about the fact that it will not continue to support or work on this feature. That's rare. Most tech company promises aren’t broken explicitly, they just remain undelivered long enough to be forgotten. 

This is particularly disappointing as other companies take even bigger swings, like Google and Apple working together to implement end-to-end encryption over Rich Communication Services (RCS), and Signal’s continued work to make its app simpler and easier to use for everyone.

Meta abandoning this principle is disheartening, especially as we are still waiting for other promised features from the company, like end-to-end encryption in Facebook Messenger group messages. Instead of blaming users for not using these sorts of features and then abandoning the promise of delivery, Meta—and other tech companies—should start by enabling strong privacy protective features by default.

This week, Apple released iOS 26.5, an update that supports end-to-end encryption for Rich Communication Services (RCS), meaning conversations between Android and iPhone will soon be encrypted in the default chat apps. This has been a long time coming, and is a welcome delivery on a promise both Google and Apple made.

With this update, conversations that take place between Apple’s Messages app and Google Messages on Android will be end-to-end encrypted by default, as long as the carrier supports both RCS and encrypted messages (you can find a list of carriers here). RCS messages are a replacement for SMS, and in 2024 Apple started supporting it, making for a marked improvement in the quality of images and other media shared between Android and iPhones. 

Now, those conversations can also benefit from the increased privacy and security that end-to-end encryption offers, making it so neither Google, Apple, nor the cellular carriers have access to the contents of messages. This feature comes courtesy of both Apple and Google supporting the GSMA RCS Universal Profile 3.0, which implements the Messaging Layer Security protocol for encryption. Metadata will likely still be collected and stored for these conversations, making alternatives like Signal still a better option for many conversations. Likewise, if you back up those conversations to the cloud, they may be stored unencrypted unless you enable Advanced Data Protection on iOS (Google Messages end-to-end encrypts the text of messages in backups, but not the media, so we’d like to see a similar offering as ADP on Android). Still, this is a significant step forward for the privacy of millions of conversations worldwide.

End-to-end encrypted RCS messaging is still marked as beta on Apple devices, likely because the rollout is dependent on carriers as well as the Android phone running the most recent version of Google Messages. 

It might take some time before you get this feature in your chats and until you do, remember that the conversations are not protected with end-to-end encryption. But once everyone in the conversation is on the right software version and the carrier support is implemented, you will see a lock icon and the text, “Encrypted” at the top of the conversation for any chats you have over RCS, as seen here:

We applaud Apple and Google for getting this across the finish line and Encrypting It Already! More companies should take these sorts of difficult but necessary steps to protect the privacy of our conversations and our data.
