Beef up your online security and privacy of your chats with the best secure messaging apps available on Android and iOS devices.

It’s no brainer that we all communicate through our messaging apps. And, it’s no rocket science that we want to keep our private conversations private!

From awkward first time conversations with your crush to office gossip, or opening up about your feelings, no one wants their private conversations to be seen by third-parties nor be swamped with unnecessary ads.

The fact of the matter is that unless you’re secured with an encrypted messaging app, you’re simple exposing your private chats out in the open.

How to choose a secure messaging app

There are dozens of messaging apps available on the Play Store and the App Store, but not all of them offer the security they claim to provide. When choosing a secure messaging app, it goes without saying that you should opt for an app that offers end-to-end encryption by default.

Here’s a list of the top 5 best secure messaging apps:

  1. Signal

Signal Messenger, initially released in 2018 is free and open-source software that is headquartered in Mountain View, CA. Signal messenger gained widespread recognition for being the most secure messaging application available in the market.

Signal is an instant messaging, voice calling and video calling application that is available on iOS and Android phones. The app uses end-to-end encryption protocols that secure any and all messages sent to other Signal users.

Apart from sending and receiving messages, Signal is used for wide purposes such as sending and receiving encrypted group messages, attachments and media messages to other Signal users.

What’s interesting about the app is that it has an integrated mechanism for authenticating that no man-in-the-middle attack occurs.

  1. WhatsApp

By far, the most popular and widely used messaging app, WhatsApp, has over 1 billion active users. With an easy-to-use interface, WhatsApp offers features such as location and file sharing, gifs, and even desktop support.

The app comes equipped with the industry’s highest level of encryption protocol. The encryption features Perfect Forward Secrecy (PFS). What this encryption standard means is that if a snooper intercepts your communications, all they’ll be able to see is the last message you’ve sent. Everything else will remain private.

To fully secure your communications, however, you’ll need a robust VPN that is renowned for offering highest-graded encryption. Learn more about WhatsApp’s encryption.

  1. Skype

Skype is a widely popular messaging app that’s used by businesses and individuals alike. Skype claims that all Skype-to-Skype voice, video, file transfers, and instant messages are entirely encrypted. The encryption offered by Skype protects you from vulnerabilities such as eavesdropping by malicious users.

Skype uses the AES (Advanced Encryption Standard*), also known as Rijndael, which is used by the US Government to protect sensitive information, and Skype has, for some time, always used the strong 256-bit encryption. User public keys are certified by the Skype server at login using 1536 or 2048-bit RSA certificates.

When communicating on Skype, your communications are secured from the server end. Learn if your business communication are secure on Skype.

  1. Facebook Messenger

The infamous messenger app, Facebook Messenger, is a messaging app developed by Facebook. It was originally developed as Facebook Chat in 2008, but Facebook revamped its messaging service in 2010.

To get encrypted conversations on Facebook Messenger, you have to start a ‘secret conversation’ within the Facebook app. Here’s how to start a secret conversation:


Secret conversations are currently only available in the Messenger app on iOS and Android, so that they won’t appear on Facebook chat or Learn about Facebook scandal.

  1. Telegram

Telegram gained popularity in 2014. The app has over 100 million users and offers excellent features that are appreciated by many. However, the app doesn’t seem to provide just an adequate level of security needed in today’s massively monitored digital world.

Strange face about Telegram: the app doesn’t offer encryption by default. To have encrypted conversations, you need to switch on the encryption option manually. While cybersecurity experts see this is a significant flaw, it’s worth mentioning that it’s much better than other messaging apps.

Final Verdict

While there are several other messaging apps available in the market, they don’t offer topnotch encryption nor have a credible track record. Your best bet is to use industry-recognized secure messaging apps and always use a VPN to ensure your messages, voice calls, video calls, files, and much more are secured with the highest grade encryption.
