Multi-mode communication allows for users to send messages through texts, videos, and audios When a platform allows for messages to be send via multiple modes, it usually allows the user to delete whatever kind of message comes through.Encryption does not allow copies of messages to be stored anywhere, including on servers. The message only decrypts using a locally stored key or secret code when it passes from the sender to the receiver, ensuring direct secure messaging. If an app is not end-to-end encrypted, deem it non-private. Currently, this method is the safest, most private method of messaging. From the moment a message is typed, to the time it spends in transit, to the second it’s received, no one else can see that message. End-to-end encryption is a way of creating secure messaging apps by encrypting information so that only the players engaged in communication can read the messages, excluding Internet service providers, the app maker, the government or anyone else.End-to-end encryption, multi-mode messaging, and synchronization among different platforms/devices are the three main keys to look for when deciding on the best messaging program to use. Secure messaging can involve a lot of elements, so we have chosen the most important factors to qualify an application to be a secure messaging app.

Synchronization Across Platforms/Devices (mobile, desktop, web).
