WhatsApp Now Has Its Own Version of Apple's 'Lockdown Mode'
Not to be outdone by Apple's "Lockdown Mode," Meta is rolling out new security features for WhatsApp designed to protect high-risk users—journalists, activists, and government officials, for example—from cyber attacks. Strict Account Settings is a "lockdown-style" mode that builds on the platform's existing end-to-end encryption, adding stronger privacy features and additional restrictions against unknown contacts.
For most WhatsApp users, this level of lockdown is overkill. However, people with access to sensitive data that is potentially valuable to threat actors actually have been targeted with spyware campaigns through messaging platforms like WhatsApp, so for users like that, it may be a lifesaver. (In the last year, WhatsApp has also patched multiple zero-day exploits that allowed spyware to proliferate.)
As noted, the new WhatsApp settings are similar to Apple's Lockdown Mode, an OS-level feature that blocks attachments, link previews, and communication from unknown contacts alongside some other settings changes. It also disables wired connections to external devices and a range of web features. Android's Advanced Protection offers similar functionality.
How WhatsApp's Strict Account Settings protects high-risk users
Strict Account Settings automatically enables existing privacy and security settings and adds a host of restrictions to users' communication and visibility on WhatsApp.
Two-step verification and security notifications, which alert you if a contact's security code changes, are turned on.
Link previews are disabled
High volumes of messages from unknown accounts are blocked
Only your contacts or those added to a pre-established list can see information about you, including your last seen and online, profile photo, about details, and links on your profile.
Only known contacts or those on your pre-established list can add you to groups.
How to enable Strict Account Settings on WhatsApp
These controls can be enabled by going to Settings > Privacy > Advanced and toggling on Strict account settings. Settings must be changed on your primary device and cannot be updated on the web. Note that the feature will roll out gradually over the coming weeks, and may not be immediately available.
