How to Hide WhatsApp Chats: Secret Codes and Chat Lock Guide

Direct answer: To hide chats on WhatsApp securely, you can use two built-in features offered by the application. The first is the Archive feature, activated by swiping a chat to the left (on iOS) or tapping and holding the chat and selecting the archive icon (on Android). To prevent archived chats from returning to your main chat screen when you receive new messages, toggle on "Keep chats archived" in your app's Chat settings. The second, more secure method is Chat Lock, which moves selected chats into a hidden folder protected by Face ID, fingerprint scan, or your device passcode. For absolute privacy, you can set a custom Secret Code within the locked folder settings and toggle on the option to hide the folder entirely; this makes your private chats invisible on your main screen, allowing them to appear only when you type your secret code directly into the WhatsApp search bar.

Why on-device chat privacy is essential in today's world

Since smartphones act as extensions of our personal and professional lives, maintaining privacy on our physical devices is a constant challenge. Leaving your phone on an office desk or handing it to a friend to show a photo exposes your entire chat history. WhatsApp stores intimate messages, sensitive business discussions, and private media files. Without proper protections, anyone holding your unlocked device can read your private data.

To address this vulnerability, Meta developed local privacy controls. These features let you keep the app active and unlocked, while keeping specific conversations hidden from prying eyes. This prevents quick, unauthorized snooping in shared environments. Having an on-device privacy filter keeps your personal conversations separate from casual device-sharing moments, protecting you in daily life.

In addition to hiding specific chats on your screen, locking down the entire app with secondary security PINs is a vital defense against digital hijacking. If you want to configure an app-wide passcode lock, check our step-by-step guide on how to lock WhatsApp with password.

Method 1: Archiving chats (Basic Ocultation)

Archiving is the simplest way to clean up your WhatsApp home screen by hiding old or inactive chats without deleting them permanently. However, by default, if an archived chat receives a new message, it will automatically return to your main chat screen. To prevent this, you must change your settings:

Step 1: Enable "Keep Chats Archived" in settings

1. Open WhatsApp on your mobile phone.
2. Navigate to the Settings menu.
3. Tap on Chats.
4. Scroll down to the Keep chats archived toggle and switch it on.

Once enabled, archived conversations will stay in the Archived folder permanently, even when you receive new message notifications from those contacts.

Step 2: Archive your selected chats

• On iOS (iPhone): On the main chat list, find the conversation you want to hide, swipe it from right to left, and tap the grey Archive button.
• On Android: Tap and hold the chat you want to hide, then tap the archive icon (a box with a down arrow) in the top menu bar.

Understanding Chat Archiving vs. Chat Locking

While both features remove chats from your main conversation list, they serve completely different security purposes. Archiving is an organization tool rather than a true security wall. It is designed to declutter your list. Anyone who gains access to your unlocked phone can tap the "Archived" folder at the top of the screen and read all the messages inside. No passwords or fingerprint checks are required. Chat Lock, on the other hand, is a security barrier. It encrypts the chat log on your device storage and hides it behind your phone's biometrics. If someone opens your phone, they cannot open locked chats without your face or fingerprint. Furthermore, locked chats are completely excluded from general device search indexes, meaning their content won't show up in search results unless the folder itself is unlocked.

Method 2: Tranking chats with biometrics (Chat Lock)

For sensitive or business-related conversations, use the Chat Lock feature. Locking a chat moves it into a secure, hidden folder called "Locked Chats" that is protected by Face ID, Touch ID, or your device passcode.

To enable Chat Lock on a conversation:

1. Open the specific individual or group chat you want to lock.
2. Tap the contact or group name at the top of the screen to open the profile info.
3. Scroll down and tap Chat Lock (or "Lock chat").
4. Toggle on the option to lock the chat and confirm with your face scan, fingerprint, or device passcode.

Once locked, you can access the secure folder by swiping down on your main chat list. Tap the "Locked Chats" folder and scan your biometrics to reveal your hidden conversations. If your phone's biometric scanners fail due to screen drops or hardware wear, see our troubleshooting guide on what to do when Face ID not working errors occur.

Method 3: Secret Codes (Advanced Invisible Mode)

While the standard Chat Lock folder hides your messages, the folder itself still appears at the top of your screen if you swipe down on the chat list. This can alert others that you are hiding chats. To make the folder completely invisible, you can create a custom Secret Code.

To set up a secret code and hide the locked folder:

1. Open WhatsApp and swipe down on your chat list to reveal the Locked Chats folder.
2. Tap the folder and unlock it using Face ID or your fingerprint scan.
3. Tap the three dots (on Android) or the settings gear icon (on iOS) in the top right corner of the folder.
4. Tap Chat Lock Settings.
5. Select Secret Code, then tap Create Secret Code.
6. Enter a custom code using letters, numbers, symbols, or emojis. Re-enter the code to confirm.
7. Toggle on the option to Hide Locked Chats.

Once activated, the Locked Chats folder will vanish from your chat list entirely. To reveal it, tap the search icon in the top right corner of your main WhatsApp screen, type your secret code into the search bar, and the hidden folder will appear instantly.

Managing hidden chats across multi-device environments

In today's digital workflow, many users run WhatsApp on multiple screens, including laptops, tablets, and smartwatches. It is important to know how these secondary devices handle your hidden chats. Standard archived chats sync across all devices, remaining tucked away in the Archived folder on WhatsApp Web and Desktop. However, Chat Lock is a device-specific privacy setting. When you lock a conversation on your phone, it does not automatically lock or hide it on WhatsApp Web or Desktop unless those apps support the feature. On many secondary devices, locked chats are completely hidden from the chat list and cannot be viewed at all. This acts as a safeguard, ensuring that if you leave your desktop app open at the office, colleagues cannot browse the messages you locked on your phone. Smartwatches also filter these alerts, hiding sender details and chat content from WearOS or Apple Watch notifications when a chat is locked.

Hiding message previews from your phone lock screen

Hiding chats inside the app is only effective if you also hide message previews from your system notifications. By default, incoming notifications display the sender's name and a preview of their message on your lock screen. To turn off these previews:

Notification adjustments on iOS (iPhone)

1. Open the iOS Settings app and tap Notifications.
2. Scroll down and select WhatsApp.
3. Under Options, tap Show Previews.
4. Change the setting to Never or "When Unlocked."

Notification adjustments on Android

1. Open Android Settings > Apps > WhatsApp > Notifications.
2. Tap on chat notifications and toggle off Use high priority notifications to stop previews from popping up at the top of your screen.
3. Optionally, go to your phone's lock screen settings and select "Hide sensitive content" to keep all message details hidden.

If notifications stop appearing entirely or your app has trouble syncing messages, check if there is a connection issue. See our guide on how to fix WhatsApp Web not working to resolve background data synchronization bugs.

Advanced privacy and device maintenance tips

For complete control over your account privacy and device performance, follow these recommended practices:

• Check linked devices regularly: Open the "Linked Devices" menu in your settings to ensure no unauthorized computers have active sessions syncing your chats.
• Use encrypted backups: Turn on end-to-end encryption for your cloud backups. If you delete chats by mistake before setting up your passwords, see our guide on how to recover WhatsApp messages without backup to restore local files.
• Avoid untrusted links: Never click on suspicious links sent in chats to protect your device from security threats. If your phone loses signal unexpectedly and you suspect you have been blocked, see our guide on how to know if you are blocked on WhatsApp to test your connection.
• Monitor device temperatures: If your phone runs hot while handling heavy data encryption or locked chat directories, read our guide on iPhone overheating causes to protect your hardware components.

Conclusion

Hiding chats on WhatsApp is an important step to secure your personal data in shared environments. Whether you choose to archive conversations, lock chats behind Face ID, or use a Secret Code to hide the locked folder entirely, these native tools offer strong privacy protections. Combining these settings with hidden notification previews and encrypted backups ensures your chats remain private and secure on your device.
