If you’ve been active on social media platforms, you might have seen people comparing WhatsApp to its competition like Telegram, Signal, etc., over the past few days. Have you wondered why? Whenever we think of communicating with others, we usually think of Facebook Messenger and WhatsApp. However, the two apps weren’t as secure as they seem.

According to WhatsApp’s new policy update, the company will now share user data with other Facebook companies. Prior to the new policy update, every conversation on WhatsApp was protected with end-to-end encryption.

Driven by concerns about data privacy, users have already switched to different messaging apps that care about user privacy. There are many WhatsApp alternatives that offer similar functionality and better privacy options.

WhatsApp vs Signal vs Telegram: security and features

In this article, we will compare the three best instant messaging apps for Android. We will compare the security protocol and functionality of three main apps – Telegram, WhatsApp and Signal. Let’s check.

1. WhatsApp


Over the years, WhatsApp has been known for its end-to-end encryption. What is more important is that WhatsApp allows end-to-end encryption on all communication modes of the app.

It just means that all your voice calls, video calls, photos, videos that you share on the platform have been end-to-end encrypted on WhatsApp.

It should also be noted that Open Whisper System originally developed the end-to-end encryption protocol used by WhatsApp. For those who don’t know, Open Whisper System is also a developer of the Signal messaging app.

The only downside to WhatsApp is that it doesn’t encrypt any form of backup. Additionally, it does not encrypt the metadata used to transport communication between the two endpoints.


WhatsApp is currently the main messaging app available for Android and iOS. The app uses your phone’s internet connection to exchange text messages, make voice and video calls, etc.

Besides the regular instant messaging features, WhatsApp also offers disappearance messages, WhatsApp payment, etc. If we are talking about group chats, the app supports group chat with up to 256 members. Group video calls were limited to 8 users at a time.

Besides the communication features, WhatsApp also has a feature called “Status”, similar to Instagram Stories. You can even use the app to exchange files and documents, but there are file size limits.

2. Signal


When it comes to security and privacy, no other instant messaging app can match Signal. Signal is a messaging app that takes user privacy and security very seriously.

To protect users, it uses the open source signal protocol to implement end-to-end encryption. What’s more important is that it enforces end-to-end encryption on all forms of communication available in the app.

What makes the signal better than WhatsApp is its Sealed Sender protocol. It’s a new way of communicating where no one will be able to know who is sending a message to whom, including Signal.

Unlike WhatsApp, Signal also encrypts your metadata, preventing authorities from knowing to whom and when you sent the messages and for how long. Yes, the signal also allows you to create local encrypted backups.


While Signal beats both WhatsApp and Telegram on its own on the security front, it falls short when it comes to features. It doesn’t have any features like status, payments, etc., but it does have all the necessary features.

You can exchange text messages, make voice and video calls on the platform. Additionally, Signal allows you to create a group to start a text conversation between multiple users, but you cannot broadcast messages to multiple contacts. The latest version of the app also has the group call feature.

Some of Signal’s unique features include the ability to hide IP address, private browsing keyboard, dark mode, powerful photo editor, and more. It also supports emojis and privacy stickers, but their number is very limited. Overall, Signal is the right choice.

3. Telegram


Over the years, we have wondered whether Telegram is the best choice for security and privacy. However, this section will change the way you think. In fact, Telegram’s security is questionable and it doesn’t come close to what WhatsApp and Signal offer.

Telegram supports end-to-end encryption, but it is limited to secret chats only. It just means that the messages you exchange through secret chats are only encrypted, and regular conversations are not.

Additionally, there is one important thing to note here. According to Telegram, the company manages its message storage and decryption keys in a way that would require court orders from multiple legal systems to access any of your data.

So far, the company has not shared any data with third parties and the government. In the secret chats function, Telegram uses its own encryption protocol, MTProto. The protocol is acceptable, but it is a closed source protocol. Thus, security researchers cannot verify the protocol used to encrypt cats.


While Signal and WhatsApp offer features that users would really need, Telegram is overloaded with features. Some features of the app were really useful, but others were just there for no reason. Yes, you get basic features like text chats, group chats, and channels.

While WhatsApp has a group limit of 256 members, Telegram allows users to create groups of up to 200,000 members. Telegram focuses more on groups than on individual chats. In fact, maybe you or your friends are using Telegram just to use the channels to download stuff.

Telegram offers several group-specific features like bots, polls, quizzes, hashtags and more to improve the group experience for users. The platform is also the best for file sharing because it doesn’t compress your files.

There are a few other features like disappearing messages, app locker, scheduling messages, video calling etc.
