WhatsApp’s New Privacy Lockdown Mode: One-Toggle Security

▼ Summary

– Meta is introducing a new “Strict Account Settings” feature for WhatsApp that consolidates multiple security options into a single toggle for enhanced protection.
– This lockdown mode restricts profile visibility, limits group additions, disables link previews, blocks unknown senders, and enforces two-step verification by default.
– The feature is designed for high-risk users like journalists but will be available to all WhatsApp users globally in the coming weeks.
– Meta denied any connection between this security update and a recent lawsuit alleging misleading encryption, calling the lawsuit frivolous and false.
– Separately, Meta announced it replaced a C++ media library with a Rust-based one for improved safety and plans to accelerate Rust adoption across its systems.

For those seeking a straightforward way to enhance their messaging security, WhatsApp is introducing a consolidated privacy feature. This new option bundles several existing protective measures into a single, easy-to-activate switch, offering a more robust defense for users concerned about digital safety. The move simplifies what was previously a multi-step process, making advanced security accessible with one tap.

The feature, named Strict Account Settings, is located within the Privacy and Advanced menus on both iOS and Android. Once activated, it enforces a comprehensive set of restrictions designed to increase user invisibility and control. Profile photos, last seen timestamps, and online status become visible only to contacts. The setting also limits who can add the user to groups, disables link previews, and blocks high-volume messages from unknown numbers. Crucially, it automatically enables two-step verification and turns on notifications for any changes to the account’s security code.

A key aspect of this lockdown mode is its all-or-nothing nature. Once the main Strict Account Settings toggle is switched on, users cannot individually disable the specific protections within it. This design ensures the security configuration remains intact without potential gaps introduced by user error.

Meta positions this tool as especially valuable for individuals at heightened risk of targeted cyber attacks, such as journalists, activists, and public figures. The company emphasized, however, that the feature will be available to all users globally in the coming weeks, upholding its commitment to privacy for everyone. The announcement was made independently of recent legal challenges; Meta strongly denied allegations in a new lawsuit questioning the integrity of its end-to-end encryption, calling the claims “categorically false and absurd.”

In a related development underscoring its focus on security infrastructure, Meta also revealed it has replaced an older media processing library written in C++ with a new one built using the Rust programming language. The company praised Rust for being smaller, safer, and easier to maintain, noting its successful implementation at a global scale within WhatsApp. This new library handles media and document files, performing validation checks to mitigate risks from maliciously crafted content. Following a trend also seen at other major tech firms, Meta indicated plans to accelerate its adoption of Rust across more systems in the future.
