Messaging Layer Security (MLS) is a security layer for end-to-end encrypting messages. It is maintained by the MLS working group of the Internet Engineering Task Force, and is designed to provide an efficient and practical security mechanism for groups as large as 50,000 and for those who access chat systems from multiple devices.[1][2][3]
