While WhatsApp stands undefeated given a large number of users, we can’t avoid the developing market and popularity of Telegram and Signal. 

The update in WhatsApp’s privacy policy has given a chance for the market for these two other giants to grow.

WhatsApp 

WhatsApp has all the ingredients for a perfect recipe. This social messaging app has also added a payment feature to its hat. Users can add up to 256 members in the group. You can broadcast messages to various contacts, and also support voice and video calls, both for people and groups.

    • A Note to Self feature is also a highlight of the app. You can share your thoughts and ideas under this feature.
    • Signal permits relay voice calls to its users, identity isn’t shared, same as using a VPN 
    • Signal uses back-end user-facing encryption administration 
    • It uses the open-source Signal Protocol to accomplish end-to-end encryption

WhatsApp vs Signal vs Telegram: Which Messaging Giant is More Secure?

WhatsApp doesn’t encrypt backups (cloud or local). Whatsapp also doesn’t encrypt metadata, not at all like Signal, which is used to convey conversations between two endpoints. WhatsApp group chats have been before discovered to be filed on Google search, significant information breach. 

Telegram group chats are not encrypted except if you use Secret Chats, which again just lets you chat to one contact at a time. 

Regarding client security, Signal offers the most secure communication you can find on the internet. But the most secure app Signal falls short when it comes to all the fancy features WhatsApp and Telegram are offering. Signal naturally encrypts all the local files with a 4-digit passphrase. It also encrypts all the group calls.

What Sets Signal App Apart

FACEBOOK  DOESN’T OWN SIGNAL

It has been shown to us time and time again that we cannot trust Facebook with our personal data. However, well over a billion people decide to send their most personal messages over apps made by the organization. And keeping in mind that Facebook says it can’t access messages sent over WhatsApp and doesn’t access messages sent via Facebook Messenger. But the organization mines your use of those apps for other information, for example how frequently you chat with somebody and whose contact numbers you have saved in your contact list. 

Facebook doesn’t permit outside protection and security specialists to assess its data collection methods, nor the code of its messaging apps. That implies we simply need to take their word for it and trust that they are not taking advantage of any personal information. Also, many studies have shown that not a lot of people are willing to trust the organization with their data.

SIGNAL DOES NOT MINE USERS DATA FOR AD TARGETTING

So why escape from Facebook Messenger and WhatsApp to Signal and not some other messaging app? Since Signal is the only major messaging platform that can run on various platforms (such as android and ios) and avoids following you and your connections to other people. All the other major apps out there track you. And while Apple messages don’t. They are only available to iOS and macOS. Android users are not that lucky, so Signal app might come in handy.

It is acceptable to such an extent that numerous other messaging apps, including Facebook Messenger, Skype, and WhatsApp, have claimed to adopt the protocol to be used in their apps. 

With regards to privacy, Signal is a sure shot winner. As we examined before, Signal just records three pieces of data about their users. This is far less data than other platforms collect. Furthermore, Signal gives you a chance to take the privacy protections a step further. There are a lot of articles that can give you detailed directions on how to create your Signal account without using your phone number.
