Verifying your Matrix devices is becoming mandatory

Summary

Act now: continue sending & receiving encrypted messagesIn April 2026, we will be rolling out a significant update to strengthen the security of your conversations: unverified devices will no longer be able to send and receive end-to-end encrypted messages via Element.

This forthcoming change aims to eliminate uncertainty and the likelihood of malicious activity by requiring all devices to be verified.Device verification mattersDevice verification acts like a hand shake between your devices, proving cryptographically to your contacts that they belong to you.
