WhatsApp Tips: 4 Hidden Features to Make Chats Safer
By Advit
11 min read
WhatsApp has become an essential app for everyday communication. People use it to talk with family, share photos, send work documents, make calls, and stay connected with friends. But even if you use WhatsApp every day, you may not know about some of its most useful features.
Several helpful tools are available inside the app’s settings and chat menus. They can help you protect private conversations, reduce unwanted calls, secure your account, and free up storage without deleting important messages.
The good news is that you do not need to be a technology expert to use them. Most of these features take only a few taps to set up.
In this guide, we will explore four useful WhatsApp features that can make your chats smarter, safer, and easier to manage. We will also explain how each feature works, where to find it, and when it is worth using.
Note: WhatsApp features and menu names can vary by phone, app version, and rollout availability. Update WhatsApp to the latest version available for your device if you cannot find a particular option.
1. Advanced Chat Privacy: Keep Sensitive Conversations More Private
Not every WhatsApp conversation is meant to be shared outside the chat. You might discuss a personal matter with a friend, exchange sensitive information in a group, or organize something that should stay within a particular conversation.
WhatsApp’s Advanced Chat Privacy feature adds another layer of control over how chat content can be taken outside the app.
When enabled, it restricts certain actions, including exporting the chat, automatically saving media to a device’s gallery, and using messages in that chat for Meta AI features.
This can be especially useful in groups where members do not all know each other well.
How to turn on Advanced Chat Privacy
Follow these steps:
Open WhatsApp on your phone.
Open the individual or group conversation you want to protect.
Tap the contact’s name or the group name at the top.
Find and select Advanced Chat Privacy.
Turn the setting on if it is available.
For group conversations, group administrators can enable this setting. In individual chats, either participant can enable it. The setting needs to be applied to each conversation separately. <Cite refs={[“turn100521search6″,”turn100521search1”]}/>
Why is this feature useful?
Imagine that you are part of a private community group discussing a sensitive issue. You may want members to participate without making it easy to export the conversation or automatically save shared media.
Advanced Chat Privacy adds restrictions that can help in this situation.
It is also useful for people who share information in work-related groups or private discussions and want more control over how that information is handled.
Is Advanced Chat Privacy a complete security guarantee?
No. It adds restrictions, but it cannot guarantee that nobody will copy or share information. For example, another participant might photograph the screen using a different device.
Use this feature as an additional privacy measure, not as a replacement for careful sharing habits.
Best tip: Enable Advanced Chat Privacy for conversations where extra restrictions are helpful, especially when discussing sensitive subjects with a group.
2. Chat Lock: Protect Your Personal Conversations
Do you sometimes lend your phone to a family member or friend? If so, you may prefer to keep certain conversations out of your regular chat list.
WhatsApp’s Chat Lock feature helps you do that. It moves a selected conversation into a separate Locked Chats folder protected by your device’s authentication method or a supported secret code.
Depending on your device and settings, you can use a fingerprint, face authentication, your phone’s passcode, or another supported authentication method.
When a chat is locked, its notification details are also hidden to help protect the contents of incoming messages. <Cite refs={[“turn100521search2″,”turn100521search9”]}/>
How to lock a WhatsApp chat
Open WhatsApp.
Open the individual conversation or group you want to protect.
Tap the contact’s name or group name to open the chat information screen.
Find the Chat Lock option.
Follow the on-screen instructions to enable the lock.
After setup, the conversation should appear in the Locked Chats folder rather than your regular chat list.
The exact steps can differ across Android, iPhone, WhatsApp Web, and desktop versions.
What if you want to hide the Locked Chats folder?
On supported devices, WhatsApp offers a secret-code option that can hide the Locked Chats folder from the main chat list. You can then access it using the configured secret code.
This option is useful if you want an additional level of privacy beyond simply moving conversations into a locked folder.
Look for the secret-code settings within the Chat Lock interface if the option is available on your device.
When should you use Chat Lock?
Chat Lock can be helpful when:
You share your phone with family members.
You want to protect personal conversations from casual viewing.
You receive private messages that should not appear in ordinary notifications.
You want to separate sensitive conversations from your everyday chats.
Remember that Chat Lock protects access to selected conversations. It does not make your entire phone secure if someone can unlock the device or access your account through another method.
Best tip: Use Chat Lock for conversations you would not want someone casually browsing through if they were holding your phone.
3. Stronger Account Security: Protect WhatsApp From Account Takeover
Privacy is not only about hiding messages on your phone. It is also about protecting your WhatsApp account from people who may try to take it over.
Scammers sometimes pretend to be friends, relatives, customer-support representatives, or other trusted contacts. They may ask for a verification code or try to persuade you to approve a login request.
WhatsApp has several security tools to help users protect their accounts. In an August 2026 announcement, the company described stronger two-step verification using a password that can include letters, numbers, and special characters. WhatsApp also highlighted passkeys and additional context for calls from unknown numbers. <Cite refs={[“turn100521search4”]}/>
Enable two-step verification
Two-step verification adds an extra layer of protection when someone attempts to register your phone number with WhatsApp.
To check your settings:
Open WhatsApp.
Go to Settings.
Select Account.
Open Two-step verification, if shown.
Follow the instructions to configure the available protection.
Depending on your app version and rollout, you may see a PIN or the newer password-based option.
Choose a strong, unique credential that you do not use for other accounts. Keep recovery information up to date where WhatsApp offers it.
Consider setting up a passkey
A passkey allows you to verify your identity using a supported method, such as your fingerprint, face recognition, or device screen-lock credentials.
To check whether the option is available, open:
WhatsApp → Settings → Account → Passkeys
Follow the on-screen instructions to set it up on your device.
Passkey availability and setup requirements can vary by device and account.
Be careful with verification codes
This simple habit is just as important as enabling security features.
Never share your WhatsApp registration code or account PIN with another person. A person claiming to be a friend, employee, or support representative should not need you to reveal these credentials.
If a stranger calls unexpectedly and asks you to verify your account, stop and check the situation independently.
Silence calls from unknown numbers
WhatsApp also offers a feature called Silence Unknown Callers. It can prevent calls from unknown numbers from ringing your phone, while those calls remain visible in your call history.
To enable it, open:
WhatsApp → Settings → Privacy → Calls → Silence Unknown Callers
The menu may differ slightly depending on your device.
This can help reduce interruptions from unwanted calls. However, it does not block every possible scam or prevent unknown callers from attempting to contact you through other methods. <Cite refs={[“turn100521search3″,”turn100521search0”]}/>
Best tip: Use two-step verification or a passkey where available, never share account codes, and consider silencing unknown callers if you frequently receive unwanted calls.
4. Manage Chat Storage: Free Up Space Without Deleting Important Conversations
WhatsApp conversations can accumulate hundreds of photos, videos, voice messages, documents, and forwarded files.
Over time, this media can take up a significant amount of storage on your phone. You may notice that your device has less free space for new photos, apps, downloads, or system updates.
The solution is not necessarily to delete entire conversations.
WhatsApp’s storage-management tools let you identify large files and remove unwanted media while keeping the rest of a chat’s history.
How to find and delete large WhatsApp files
Open WhatsApp.
Open the chat that is taking up too much space.
Tap the contact’s name or group name.
Select Manage Storage, if available.
Review the media and files listed.
Select the items you no longer need.
Confirm the deletion after checking your selection.
WhatsApp has also announced options for clearing media separately from chat history when clearing a conversation. This can help users free up space without removing every text message. <Cite refs={[“turn100521search5”]}/>
What should you delete first?
Start by reviewing items such as:
Large videos shared in busy groups.
Duplicate photos and forwarded clips.
Old documents you have already saved elsewhere.
Media from conversations that are no longer active.
Files you can easily download or receive again.
Be careful before deleting anything important. A document or photograph may be difficult to recover if you have no separate copy.
Keep storage under control
You do not need to wait until your phone is almost full to manage WhatsApp media.
Make it a habit to review large files every few weeks, especially if you belong to groups that regularly share videos and images.
You can also review WhatsApp’s media auto-download settings to control which files download automatically over mobile data or Wi-Fi.
The available options may differ across Android and iPhone.
Best tip: Remove large, unnecessary videos before deleting entire chats. This often gives you a more practical way to free up space while keeping useful conversations.
Bonus WhatsApp Tips for Everyday Use
The four features above are a good starting point, but a few additional habits can make WhatsApp easier to manage.
Review your privacy settings
Open Settings → Privacy and check who can see your profile photo, last seen, online status, About information, and Status updates.
Choose the settings that suit your needs instead of leaving every detail visible to everyone.
Use disappearing messages when appropriate
WhatsApp allows disappearing messages in supported chats. You can choose an available duration so that new messages disappear automatically after the selected period.
This can help reduce the amount of conversation history retained in a chat. However, disappearing messages do not guarantee that nobody has saved or copied the content before it disappears.
Check linked devices
Review the devices connected to your WhatsApp account. If you see a device you do not recognize or no longer use, log it out.
This is particularly useful if you have previously linked WhatsApp to a computer or another device.
Keep WhatsApp updated
Updates can include security fixes, bug fixes, and new features. Install updates through your device’s official app store and avoid unofficial WhatsApp applications that claim to offer extra privacy or hidden features.
Final Thoughts
WhatsApp has many useful tools beyond sending messages and making calls. You can use Advanced Chat Privacy to add restrictions to sensitive conversations, Chat Lock to protect selected chats, account-security options to reduce the risk of account takeover, and storage management to remove unwanted media.
The best part is that you can start using these tools without changing how you normally chat.
Begin with the feature that solves your biggest problem. If privacy matters most, review Chat Lock and Advanced Chat Privacy. If you receive suspicious calls, consider silencing unknown callers and strengthening your account security. If your phone is running out of space, start by reviewing large WhatsApp files.
A few minutes spent checking these settings can make everyday messaging more comfortable and easier to manage.
