Also know, is Viber really secure?
Yes! Viber uses end-to-end encryption. It protects messages from being read by a third party. The message coming from your device is encrypted before it is sent to your contact.
Also, is Viber safer than messenger? Facebook messenger doesn't offer automatic encryption but allows users to set it up themselves. WhatsApp and Viber, however, both tout their end-to-end encryption is automatic and makes it so even they can't access your messages, which leads many users to believe their conversations are secure.
Similarly, you may ask, is Telegram really private?
Telegram has marketed itself as a secure messaging app. There are indeed ways to keep chats private on Telegram, but only if you know how. Unlike WhatsApp and iMessage, Telegram conversations aren't encrypted end-to-end by default. The problem is that some users don't seem to be aware of the risks of using Telegram.
What is so special about telegram?
Telegram's core functionality is the same as most other messaging apps: You can message other Telegram users, create group conversations, call contacts, and send files and stickers. So, for the average person, using Telegram doesn't necessarily mean their messages are more private or secure than when using WhatsApp.
