WhatsApp is expanding privacy controls with a feature that lets you lock and hide individual chats directly inside the app. This update, first spotted by TechCrunch, gives users more granular control over message visibility on shared or personal devices.
The new option integrates with native screen lock methods, adding a layer of security without changing how people use the service day to day. Below is a quick overview of what this means for privacy, compatibility, and setup.
| Feature | Description | Availability | Device Requirements |
|---|---|---|---|
| Lock individual chats | Apply app-level lock to specific conversations | Gradual rollout | iOS and Android with recent app version |
| Biometric or PIN unlock | Use fingerprint, face recognition, or custom PIN | Optional, based on device support | Compatible biometric hardware or secure lock screen |
| Hidden chat list | Selected chats do not appear in main conversation list | Opt-in per chat | Requires re-authentication to view hidden chats |
| Quick access from navigation | Dedicated archive and lock shortcut in menu | Rollout aligned with stable release | Updated app from official stores |
App Privacy Controls and Chat Lock
How the Lock Feature Works
After enabling the setting, users select specific chats and choose to lock them. Each time someone opens a locked chat, they must verify identity through a saved biometric method or device PIN. The feature is designed to keep private conversations local to the device without storing additional data on WhatsApp servers.
Impact on Notifications and Media
Locked chats can still display message previews, but sensitive content can be hidden behind the lock screen. Media downloads remain intact, and end-to-end encryption is unaffected, ensuring that encryption in transit and at rest continues to protect messages independently of the new lock layer.
Hidden Chats and User Experience
Managing Visibility in the Chat List
Hiding a chat moves it to an archived section accessible only through a direct shortcut or after unlocking. This helps reduce clutter on the main conversation list while keeping the history intact. The change is reversible, and users can unhide any time from the archive menu.
Performance and Interface Consistency
Early testing shows minimal impact on app performance, even with multiple hidden chats. The interface adapts to different screen sizes, and the archive drawer maintains consistent navigation patterns across iOS and Android builds.
Security and Device Compatibility
Supported Authentication Methods
The feature relies on existing security mechanisms like fingerprint sensors, facial recognition, or device passwords. On supported Android devices, it connects with the Android Keystore, while iOS builds leverage the local biometric framework. If system lock changes, users must reconfirm access to maintain a smooth experience.
Platform Rollout and Versioning
Availability starts with the latest stable versions of WhatsApp and expands over time. Older devices may not see the option until they update the app to a compatible build. Keeping the app up to date ensures users can manage locked and hidden chats consistently.
Getting Started with Protected Conversations
- Update WhatsApp to the latest version from official app stores.
- Open a conversation, tap the contact or group name, and choose Lock Chat.
- Select your preferred unlock method, such as fingerprint or device PIN.
- To hide a chat, enable Hide from chat list in the same lock settings.
- Access hidden chats through the archive or the dedicated shortcut in the menu.
- Review authentication settings periodically to keep security aligned with device changes.
- Monitor app updates for refined controls and improved compatibility over time.
FAQ
Reader questions
Can I lock multiple chats at once?
Yes, you can individually select each chat and enable the lock for as many conversations as you want. There is no batch action yet, so each chat must be configured separately in the chat settings menu.
Will hidden chats appear in backups?
Hidden chats are still included in local chat backups created by the app. If you restore from a backup, the hidden status and lock settings are preserved alongside other conversation data.
What happens if I disable biometric unlock?
Switching away from biometric unlock will require you to enter your device PIN or password each time you open locked chats. This can be useful if you share your device briefly but still want to keep chats protected.
Can notifications hide message content for locked chats?
You can adjust notification settings so that locked chats hide message previews. This prevents sensitive content from appearing on the lock screen while keeping the conversations accessible from within WhatsApp.
