The Meta-owned messaging service rolled out the new “Strict Account Settings” on Tuesday (27 January), and allows users to opt in to a more secure messaging environment, with the trade-off being a more restrictive user experience.
New defence features include blocking media and attachments from unknown users, silencing calls from unknown callers, and removing link previews, all of which are tools threat actors use for scams and hacks.
“At WhatsApp, we think you should be able to have a private conversation online, just like you would in person. We will always defend that right to privacy for everyone, starting with default end-to-end encryption,” said WhatsApp.
“But we also know that a few of our users – like journalists or public-facing figures – may need extreme safeguards against rare and highly sophisticated cyber attacks.”
While not completely comparable to secure messaging applications like Signal, a number of platforms have introduced new security measures.
In 2025, Alphabet’s Android launched “Advanced Protection Mode”, while three years earlier, Apple launched “Lockdown Mode”, which it said is designed for those who may be targeted by advanced digital threats. This disables most message attachment types and link previews, and introduces restrictions on browsing and FaceTime.
WhatsApp said the new feature is just one of the ways it aims to secure its users.
“Strict Account Settings is one of many ways we’re working to protect you from the most sophisticated of cyber threats,” it said.
“We’ve also rolled out a programming language called Rust behind the scenes to help keep your photos, videos, and messages safe from things like spyware, so you can share and chat with confidence.”
