Four Ways to Secure Your Messages

In an era where digital communication is the norm, securing your messages has never been more crucial. While platforms like Apple and Google have made strides towards end-to-end encryption (E2EE), their limitations mean that some messages might still slip through the cracks, unprotected. Thankfully, there are concrete steps you can take to keep your conversations secure.

1. Choose the Right Messaging Apps

Not all messaging apps prioritize your privacy the way they claim. For example, while Facebook Messenger offers E2EE, it requires users to enable it manually. Telegram, another popular app, only uses E2EE in specific contexts.

For maximum security, opt for Signal or WhatsApp. These apps are both free and widely available, and they utilize the open-source Signal Protocol for E2EE, ensuring that your messages remain private. Signal, which operates as a nonprofit, is highly recommended for its commitment to user privacy. WhatsApp, owned by Meta, also offers E2EE but, unlike Signal, it is a commercial product (though Meta cannot view your messages).

Both platforms also support a range of features typical of modern messaging apps, from group chats to video calls. One caveat is that Signal does not back up your messages by default. As a result, you’ll need to migrate your messages manually if you switch phones. WhatsApp, on the other hand, has a robust backup mechanism that you can activate within its settings.

2. Identify When Your Messages Are Encrypted

Knowing when your messages are secure is essential. If you’re using an iPhone, you can easily check: any message sent in a blue bubble indicates E2EE protection. On Android devices using Google’s Messenger app, look for a lock icon on the send button or beneath sent messages.

If your messages aren’t encrypted, consider switching to an app that prioritizes your privacy. iPhone users should also think about enabling Advanced Data Protection, which secures backups that could include sensitive messages.

3. Utilize Self-Deleting Messages

Storing messages on your device can expose you to potential risks, such as unauthorized access or theft. To counteract this, consider configuring your settings to automatically delete older messages. On iPhones, navigate to Settings > Apps > Messages > Message History to select a time frame for how long messages remain stored on your device.

If you’re using Signal or WhatsApp, both platforms allow you to set timelines for message retention or choose to make specific messages disappear after being read only once.

4. Keep Your Phone Updated

Your phone’s overall security directly impacts the safety of your messages. Always ensure that you install the latest security updates. This practice not only protects your messages but also your device’s functionality.

Additionally, activate anti-theft features for your iPhone or Android. Remember that biometric security features, like face or fingerprint recognition, aren’t infallible. Be aware of how to disable them temporarily in case of emergency. On iPhones, press and hold the volume-up and lock buttons; then select the lock button again or tap Cancel when prompted. For Pixel phones, simultaneously press the lock and volume-up buttons and select Lockdown.

By following these strategies, you can dramatically enhance the security of your messages, ensuring that your private conversations remain just that—private.
