Instagram appears to be stepping back from end-to-end encrypted messaging — a surprising move after years of Meta, its parent company, promoting strong encryption as the future of private communication.
A notice on Instagram’s help pages now says end-to-end encrypted messaging on Instagram will no longer be supported after May 8, 2026. The page instructs affected users to download any chat messages or shared media they want to keep before that date.
They could always do that, and basically anything you can read on your phone, they can access if they need.
Encryption is a math thing: generate a pair of keys: one te encde, one to decode. I broadcast the one to encode (“public key”), and the whole world is tu use it to send me encrypted messages. I keep the decoding (“private key”) only for myself.
In client to erver encryption, we exchange keys with the server through which go all the comms: it decodes my messages and re-encodes them for my contact.
In e2e, the key exchange is between contacts: the server does not have the private keys.
In Meta, the proprietary app can send your private key to the server and then they know what you wrote. You have no way to know it doesn’t do so!
Opensource audited software is the only way to make sure.
