WhatsApp is reinforcing its position as a privacy-first messaging platform with the rollout of new features designed to protect users from increasingly sophisticated digital threats.
Building on its long-standing commitment to default end-to-end encryption, the Meta-owned messaging service is introducing enhanced protections that lock down accounts and limit how sensitive conversations can be shared, particularly for users who face elevated security risks, a WhatsApp blog conveyed.

The company says these updates are aimed at ensuring that private conversations online remain as secure as those held in person. While WhatsApp’s encryption already shields messages and calls from outside access, the platform acknowledges that certain users, including journalists and public-facing figures, require even stronger safeguards against rare but highly advanced cyber attacks.
Introducing Strict Account Settings
To address those risks, WhatsApp has announced a new lockdown-style feature called Strict Account Settings. When enabled, the setting automatically applies the most restrictive privacy controls to a user’s account, limiting how WhatsApp functions in key areas.
Under Strict Account Settings, attachments and media from people who are not in a user’s contacts can be blocked, reducing exposure to potentially malicious files. Once activated, certain account settings become locked, preventing accidental changes that could weaken security.
The feature is rolling out gradually over the coming weeks and can be enabled by navigating to Settings > Privacy > Advanced. WhatsApp describes Strict Account Settings as one of several measures designed to protect users from the most sophisticated cyber threats.
In addition to these front-facing controls, the company has also implemented the programming language Rust behind the scenes to strengthen defenses against spyware and other security vulnerabilities, helping to safeguard photos, videos, and messages.
Advanced chat privacy adds a new layer of control
Alongside account-level protections, WhatsApp is also enhancing privacy within individual chats and groups. In April 2025, the platform introduced Advanced Chat Privacy, a feature aimed at preventing content from being taken outside of WhatsApp when additional discretion is required.
When enabled, Advanced Chat Privacy blocks others from exporting chats, auto-downloading media to their devices, and using messages for AI features. This ensures that conversations remain confined to WhatsApp, giving participants greater confidence that sensitive discussions will not be shared elsewhere.
The feature is available in both one-on-one chats and group conversations, reflecting WhatsApp’s view that groups increasingly mirror real-world networks. The company notes that Advanced Chat Privacy is particularly useful in sensitive group settings, such as health support communities or local organising efforts.
Users can activate the setting by tapping the chat name and selecting Advanced Chat Privacy. This is the first version of the feature, with plans to expand protections over time. The setting is rolling out to all users on the latest version of WhatsApp.
