Whether it is for staying in touch with friends and family across the globe, run a business operation, or contact a coworker, messaging apps like Signal play a crucial role in our daily lifestyle.

We very normally share our personal pictures legal documents and business secrets on the regular messaging applications, which we obviously don’t want to make it visible to wrong people. But how much do we trust these messaging applications claiming to protect all the sensitive information and confidential messages?

Here, in this article, we will talk about why Signal- the most private messaging application is best for privacy!

Signal was all about security first, its Open source encryption is widely used by big tech companies and is trusted by security experts. But first let’s start with encryption

Almost, every messaging platform admits to offer data encryption, making use of mathematical equations for scrambling the data to stop eavesdroppers from accessing those messages.

End-to-end encryption (E2EE) is the most secure type offered by messaging applications, where the decryption keys are only available to the intended users. Along with protecting the communications from eavesdroppers, E2EE also confirms that the company hosting the communications won’t get access to the messages. Also it explains how the data will be protected against interfering warrants by advertising agencies and data breaches.

Signal was one of the first leading platforms to back E2EE encryption feature. In the past few years, some of the biggest tech companies have adopted the Signal’s encryption protocol, including WhatsApp, iMessage, Wickr and more.

When it’s about Signal, There is a lot more to it, than just security with data encryption. Have you ever had a thought about what if, the recipient’s device gets hacked or falls into some wrong hands? With that being the case, data encryption is of little use, because any malicious actor can have access to the messages in its unencrypted format.

Well, the best way to overcome this issue is to get rid of the messages, after it has been read. It is probably the most secured way of making sure that even if the device gets hacked, the malicious actor won’t get any access to the sensitive and confidential messages.

Messaging apps like Signal provide the feature of message deletion, to make the communications more secure.


Yes! In Signal, you can delete any message for all the parties to any conversation to make sure that the sensitive communication doesn’t remain in any device involved in the network.

WhatsApp also offered the “delete for everyone” feature in 2017, but it only allows the deletion of messages shared within the last thirteen hours. Talking of which, Facebook Messenger also offered the “unsend” feature recently, but it only works for ten minutes after the message has been sent.

Signal, also provides a self-destructing messages option, which means the removal of the messages from the respective devices right after the configured period ends. The feature is extremely useful for sensitive conversations, saving your effort of wiping the messages manually.

All the  messages emanates with a certain auxiliary information, termed as metadata, like the ID of both sender and the receiver, message sharing time, time when it is received and read, the IP address, device IDs, phone numbers etc.

Almost every Message server store and process such information for making sure that the message was delivered to the intended recipient on time, along with allowing users to organize the chat logs.

Despite the fact that metadata do not contains any message text, it can still be very harmful, for revealing a lot about users’ communication like their geographical location, the number of times they use the application, and people they connect with.

With this being the case, the messaging service easily falls a victim of any data breaches, where metadata can lead to cyberattacks like phishing and more.

Most of the messaging services collect humungous amounts of metadata and unfortunately, paving a way for data breaches. But do we not know that, Signal holds the best track record, concerning the issues, as the company’s policy, asks only for the registered phone number and the date the user logged in to the account last.

“open-source,” applications with their source code being available publicly, are considered to be more reliable as independent security specialists can verify whether the application is safe or not.

Signal, is an open-source messaging application, meaning that it can be peer-reviewed by technology experts. Signal, also has some tremendous support by security professionals like Edward Snowden and Bruce Schneier.

WhatsApp and Facebook Messenger even though being closed-source, make use of open-source Signal Protocol for their message encryption their messages, clearly depicts that Signal is Best for Privacy .
