10 Best Secure And Encrypted Messaging Apps For Android & iOS | 2021 Edition

We live in an age of internet surveillance and data logging. Agencies and government organizations often want access to private communications; we have had instances of CIA hacking attempts and attempts by the FBI to gain unauthorized access.

To tackle such issues, there has been a rise in secure messaging apps. These apps focus on keeping your privacy intact with a feature called end-to-end encryption (E2E).

A message is end-to-end encrypted if your service provider cannot open it on their servers, i.e., only the people you are communicating with can access the message. Neither the government nor the developers can access it.

If confidentiality is critical for your communication, check out this list of some of the best encrypted messaging apps for Android and iOS platforms. Thanks to iOS’s new privacy labels, we can now easily tell if an encrypted texting app is taking up user data.

Note: This list isn’t in order of preference; it’s a compilation of the best Android encrypted messaging apps. You’re advised to choose one as per your needs.

With its latest encryption technology, Viber has introduced end-to-end encryption services on all the available platforms- Mac, PC, iOS, and Android. 

The unique thing about Viber is that it uses a color-coded system to show how protected a conversation is. Grey color denotes encrypted communication. Green signifies encrypted communication with a trusted contact, and red means that there is an issue with the authentication key. You can also choose to hide any specific chats from your screen and access them later.

8. WhatsApp

one-to-one encrypted messaging app WhatsApp

WhatsApp is one of the most popular and secure messaging apps for Android and iOS. In 2014, the app partnered with Open Whisper Systems to integrate the same end-to-end encrypted chat protocol as Signal. The E2E encryption ensures that only the sender and the recipient can read the messages, and nobody else, not even WhatsApp.

But that hasn’t been enough to stop WhatsApp chat leaks. On top of that, WhatsApp is known to collect massive meta data which can be used to identify users. Recently, WhatsApp also announced new privacy policy changes where Facebook will have access to messages sent to WhatsApp business accounts.

On the bright side, the app has features like the ability to send voice messages, photos, videos, GIFs, video calls, group chats, location sharing, disappearing messages and much more. The app also has a Snapchat-like disappearing stories feature that can be viewed by your WhatsApp contacts.

10. Status

Status is a new player in the most secure messaging apps market. The open-source app is not only a private messenger but also has a decentralized crypto-wallet and a Web3 browser where you can access Ethereum based applications.

Apart from end-to-end encryption, the app uses peer-to-peer (p2p) messaging protocol to make messages more private and secure. You don’t need a phone number to login, instead Status uses public and private cryptographic keys that are stored on your device. Further, you need to create a “chat key and name” that’s completely unique to you.The app also allows you to join public chats.

The best part, however, is that you can send SNT which is Status’ native crypto currency token. SNT is similar to Brave browser’s BAT (Basic Attention Token) where you get rewards for being on the platform. The only problem with the app is that it is still fresh, therefore not many people are using the app.
