WhatsApp is gearing up to introduce a new strict security mode that will offer an extra layer of protection for users who believe they might be targets of cyber attacks. The feature, spotted in the latest WhatsApp beta for iOS (version 25.33.10.70) by WABetaInfo, is designed to simplify privacy management by letting users enable multiple advanced security settings at once.
The upcoming mode will reportedly roll out to beta testers in the coming weeks before reaching all users globally.
What is WhatsApp’s Strict Security Mode?
The Strict Security Mode will automatically apply the most secure privacy and safety settings across the app. It will adjust features like media sharing, call handling, and group invites without requiring users to manually tweak every option.
This mode is particularly aimed at users who feel they might be under targeted online surveillance or phishing attempts. It helps them secure their accounts with a single tap instead of navigating through multiple privacy settings.
Blocks Media and Attachments from Unknown Numbers
A key part of this mode is its ability to block media and attachments from people not in your contacts. When activated, photos, videos, and voice messages from unknown senders won’t auto-download, minimizing the risk of malware, spam, or harmful content.
Chats with unsaved numbers will also be limited to plain text messages, reducing exposure to suspicious files or links and making WhatsApp safer for high-risk users.
Disables Link Previews for Better Privacy
Normally, WhatsApp generates a preview (image and description) when users send or receive a link. However, in strict mode, this feature will be automatically disabled to prevent WhatsApp from fetching metadata from websites, a move that protects your IP address and makes it harder for websites or attackers to track your activity or location.
Silencing Unknown Callers and Limiting Group Invites
Another major privacy improvement comes from silencing unknown callers. Calls from numbers not saved in your contacts will be muted to help prevent scams, spam, and harassment.
Additionally, group invites will be limited so that only your saved contacts can add you to groups reducing the chances of being added to random or fraudulent groups.
Automatic Security Notifications for Encryption Changes
The Strict Security Mode will also make encryption-related alerts more visible. Users will receive security code notifications whenever a contact’s encryption key changes often due to reinstallation or device switch.
This ensures that users can verify the authenticity of their conversations and continue chatting securely.
Enabling Two-Step Verification by Default
To protect accounts from theft and phishing attempts, the new mode will automatically turn on Two-Step Verification. This feature adds a PIN-based verification layer whenever someone tries to register your WhatsApp number again.
Even if someone gains access to your SIM card or device, they won’t be able to hijack your account without the PIN significantly improving account safety.
Limiting Visibility of Personal Information
With Strict Mode active, profile photo, last seen, online status, and About info will be automatically limited to contacts only. This helps protect personal details from strangers and prevents impersonation or stalking attempts.

Protecting IP Addresses in Calls
Lastly, the new security mode will route voice and video calls through WhatsApp’s servers instead of direct peer-to-peer connections. This hides the user’s IP address, making it harder for anyone to track their approximate location.
While this may slightly affect call quality, it ensures maximum privacy for sensitive or confidential calls.
A Step Toward Safer Communication
With cyber attacks and phishing scams becoming increasingly sophisticated, WhatsApp’s Strict Security Mode marks a significant step toward more robust user protection. By combining multiple privacy tools into one easy toggle, WhatsApp aims to make secure communication simpler and more accessible to everyone.
The feature is currently in development and expected to reach beta testers soon before rolling out globally on both iOS and Android.
