Encrypted Messaging Apps

Using encrypted messaging apps can prevent others from snooping on your chats and calls. How can you choose a safe chat app?

End-to-end encryption is necessary, which ensures that only the sender and receiver can access the conversation content. Even better, it prevents apps from storing copies of your messages on their servers.

However, keep in mind that an unsecured device can enable anyone to access your messages. It’s essential to use a separate password or biometric like Face ID, fingerprint, or iris to lock your messaging app. Or, use a VPN for an extra layer of privacy and security.

Back to the topic, here we’d like to share with you the 10 best secret chat apps for encrypted messaging. Keep reading to know their pros and cons. Some secret chat apps are blocked in many countries. And we’ll show you how to bypass geo-blocks.

Internet security is far beyond private messaging. Data leakages happen in more than just messages, voice calls, and video calls, but on many other occasions. For example, public Wi-Fi exposes your privacy, hackers steal your data, and your ISPs track your online activities. A VPN like PandaVPN can cover your IP address and make you anonymous online. You can have one on your device.

Anyway, safe chat apps enable you to chat privately at least. The followings are detailed descriptions of the above encrypted messaging apps. Check it out.

1. Signal 

Owned by a non-profit foundation created by an anarchist cryptographer, Signal is the best encrypted messaging app, though your account is linked to your phone number.

Signal supports instant messages, group chats, voice calls, video calls, and media and file attachments. End-to-end encryption protects all of your actions on Signal. All Signal messages can be set to self-destruct after a certain period of time.

Using Signal to chat privately requires you and the person you are chatting with both to have Signal installed on your devices. This way, the encryption feature can function properly on both ends of the conversation.

FAQs about the Encrypted Messaging Apps 

Q: What makes the best messaging apps?

The followings are the main factors that make an encrypted messaging app reliable.

1) End-to-end Encryption – E2EE allows only the sender and the recipient of the messages to have the access to read them. Any other third parties including your ISP, mobile carrier, and phone/computer manufacturer can’t access them.

2) Self-destructive Messages – Messages are heavily encrypted and can self-destruct. The self-destructing messages will disappear automatically after a certain period of time, depending on your settings.

3) Open Source Software – This means the app is open to anyone that can inspect, modify, and enhance it. Open source code allows the messaging apps to be independently verified for security.

4) Minimal Data Collection – Some messaging apps may collect metadata about you, including who you talk to, how long you chat, what device you use, and even your IP address and phone number. If you mind this problem, check the user agreement carefully and choose a private chat app that doesn’t log your metadata.

Q: What is the safest encrypted messaging app?

Signal is the most secure messaging app, offering industry-leading encryption to protect your chats and calls over the internet. It is based on a combination of Curve25519, HMAC-SHA256, and AES-256 encryption protocols. It’s almost impossible to crack.

Q: Is WhatsApp truly encrypted?

The fact that Facebook owns WhatsApp makes people hesitate to believe it is an encrypted messaging app. Actually, WhatsApp is one of the easiest ways for anyone to use end-to-end encrypted messaging. It encrypts your chats end-to-end by default.

However, note that WhatsApp does collect your contact list, location, device identifiers, and transaction history, among others.

Q: Is Facebook Messenger private?

Messages you send through Facebook Messenger are not end-to-end encrypted. We do not encourage you to use Facebook Messenger for private messaging. Try the secure chat apps we recommended above.
