Security and privacy have become paramount concerns for instant messaging users. Recognizing this, Meta-owned WhatsApp has introduced a new Secret Code feature to further fortify the protection of sensitive conversations.
WhatsApp initially introduced Chat Lock in May 2023 as a security measure for private chats, limiting access to biometric authentication or screen lock. Recognizing the need for improvements, WhatsApp has now refined Chat Lock to make it more functional and secure.
Users can now initiate Chat Lock by long-pressing a conversation and selecting the “Lock chat” option, streamlining the process for added convenience. The enhanced security feature also introduces a Secret Code functionality, allowing users to set a unique password, including emojis, for accessing the Chat Lock folder.
Previously, accessing locked chats was relatively straightforward by swiping down from the chat list window. In response to this, WhatsApp has implemented a more discreet approach. Users can now choose to hide the Locked Chats folder from their chat list and access it solely by typing the secret code into the search bar. This refinement adds an extra layer of stealth to the Chat Lock feature, ensuring privacy is maintained even when the device is shared or someone has access to the phone.
WhatsApp’s commitment to user security extends beyond Chat Lock enhancements. The recent introduction of the “Protect IP Address in Calls” feature demonstrates the platform’s dedication to safeguarding user information. This feature masks users’ IP addresses during calls by relaying them through WhatsApp’s servers, adding an extra layer of protection against potential threats.
The changing landscape of messaging app security is underscored by global perspectives. The French government’s call for officials to refrain from using popular messaging apps like WhatsApp, Signal, and Telegram in favor of domestically developed alternatives reflects concerns about potential vulnerabilities in widely-used platforms.
In response, industry leaders like Meredith Whittaker, president of Signal, and Will Cathcart, the head of WhatsApp, have contested these claims, asserting that their platforms prioritize user security.
