The number of chat messages sent each day is difficult to determine, but considering that WhatsApp alone has billions of users, it is safe to assume that there are an immense volume of ongoing conversations happening at any given time.
While not all of these messages contain sensitive or private information, a significant portion of them do. It is crucial to ensure that these chats remain secure and confidential, only accessible to the intended recipients. To achieve this, it is important to practice good messaging hygiene, which may involve changing apps or adjusting settings. Here are five recommendations to get started:
1. Switch to End-to-End Encryption:
When instant messenger chats are end-to-end encrypted, they become virtually impenetrable blocks of data. Only the devices of the individuals involved in the conversation have the encryption codes necessary to unlock the data, guaranteeing that no one else can read the messages while they are in transit.
Even the developers behind the messaging software cannot access the encrypted data. Therefore, even if an unscrupulous employee wanted to snoop on your chats, they would not be able to. Additionally, if law enforcement requested copies of the conversations, there would be no useful information to hand over.

Some instant messengers, such as Signal, WhatsApp (for personal chats), iMessage, Google Messages (with RCS enabled), Facebook Messenger, and Telegram, offer end-to-end encryption. However, it is essential to check the provider’s policies if you are using any other messaging platform and consider switching to a more secure option.
2. Turn On Disappearing Messages:
Setting your messages to disappear after a specific period of time adds an extra layer of security and privacy. By enabling this feature, your messages will automatically be deleted after they have been read, minimizing the risk of someone gaining access to them, whether physically or digitally.
Facebook Messenger, WhatsApp, Signal, and Telegram are just a few examples of platforms that offer disappearing messages. In Facebook Messenger, you can make a conversation “secret” to enable end-to-end encryption and access the disappearing messages feature. Similarly, WhatsApp, Signal, and Telegram provide options to set messages to disappear within the app settings. For iOS users, older conversations in the Messages app can be manually deleted by adjusting the settings.
3. Lock Individual Conversations:
To prevent unauthorized access to your phone and all of your chats, it is crucial to lock some or all of your conversations behind a passcode or another form of lock, such as the protection on your phone’s lock screen.
WhatsApp simplifies this process by allowing you to lock the entire app through the Privacy menu in the app settings. Alternatively, you can lock individual chats by opening the desired chat, tapping the conversation name at the top of the screen, and selecting “Chat lock.” The available options may vary depending on your phone’s capabilities, such as fingerprint lock or facial recognition.
4. Regularly Update Your Messaging Apps:
Keeping your messaging apps up to date is vital for maintaining security. Developers frequently release updates that address vulnerabilities and strengthen the app’s protection against potential threats.
By regularly updating your apps, you ensure that you have the latest security features and patches. Set your messaging apps to automatically update or regularly check for updates manually to stay protected.
5. Be Mindful of Personal Information:
While secure messaging apps and strong encryption protocols offer a high level of protection, it is essential to exercise caution and be mindful of the information you share through chat messages.
Avoid sharing sensitive personal details, financial information, or any data that could be used against you. Remember that even with advanced security measures, there is still a risk of human error or accidental data breaches.
In conclusion, preserving the confidentiality and security of your chat messages is of utmost importance. By following these recommendations, such as switching to end-to-end encrypted platforms, enabling disappearing messages, locking individual conversations, regularly updating messaging apps, and being cautious about sharing personal information, you can enhance the security and privacy of your conversations in the digital realm.
