What is a common feature of Secure Messaging?

A common feature of Secure Messaging is end-to-end encryption. This means that messages are encrypted on the sender's device and only decrypted on the recipient's device. This level of security ensures that even if the message is intercepted during transmission, it cannot be read by anyone other than the intended recipient. End-to-end encryption is essential for maintaining confidentiality and protecting sensitive information from unauthorized access.

Other features mentioned, such as automatic archiving, unlimited file size, and multi-language support, may be beneficial in various messaging applications but do not necessarily define secure messaging. While these features add value and enhance user experience, they do not directly relate to the core function of securing message content.
