This technology applies encryption to messages on one device so that only the device to which the message is sent can decrypt it. Your messages are secured with a ‘lock’ and only you and the recipient have the ‘key’ to unlock them.
In other words, end-to-end encryption ensures that only you and the person you’re communicating with can read what is being sent. This includes photos, videos, voice messages, documents, and calls.
If your messages are end-to-end encrypted, it’ll be impossible for a third party to intercept and read your messages (even the app provider itself!). And for businesses, this is extremely important if your clients will be sharing personal information such as their home address or phone number.
