WhatsApp has become a part of everyday communication for millions of people. We use it to chat with friends, share photos and documents, make calls, join groups, and stay connected with family. But even if you have been using WhatsApp for years, there is a good chance that you are still missing some of its most useful features.
The reason is simple: WhatsApp does not put every feature directly in front of you. Some useful options are hidden inside chat menus, privacy settings, account settings, or storage tools. Others are features that people know about but rarely use.
In this guide, we are looking at 15 useful WhatsApp features and settings that can make your everyday experience better. These include privacy tools, storage controls, security features, multiple-account support, chat organization options, and a few features that can be especially useful when using WhatsApp across multiple devices.
Feature availability can vary depending on your phone, operating system, country, and WhatsApp version. If you do not see a particular option, make sure WhatsApp is updated to the latest version available for your device.
1. Lock Private Chats With Chat Lock
If you have a conversation that you do not want appearing openly in your normal chat list, WhatsApp’s Chat Lock can be extremely useful.
Chat Lock moves a selected conversation into a locked section that requires device authentication or another supported authentication method to access. Notifications from locked chats also hide the message content and contact information, which adds another layer of privacy.
You can use Chat Lock for individual conversations as well as group chats.
How to use Chat Lock
On a supported phone:
- Open WhatsApp.
- Find the conversation you want to protect.
- Open the chat options or chat information.
- Select Lock Chat.
- Follow the instructions to confirm your device authentication.
WhatsApp also supports a Secret Code for locked chats. This can allow you to hide the locked-chat folder and find it by entering the secret code in WhatsApp search.
One important thing to remember is that Chat Lock is not the same as blocking calls. Calls from contacts in locked chats can still come through.
For anyone who occasionally lends their phone to another person, this is one of the most practical privacy features to know about.
2. Make Messages Disappear Automatically
Not every conversation needs to stay in your chat history forever.
WhatsApp’s Disappearing Messages feature lets you set messages to disappear after a selected period. Current options include 24 hours, 7 days, or 90 days. The setting applies to new messages rather than messages that were already sent before you enabled it.
This can be useful for temporary conversations, event planning, casual discussions, or information that you do not need to keep permanently.
How to enable it
For an individual chat:
- Open the conversation.
- Tap the contact’s name.
- Find the Disappearing Messages option.
- Choose the duration you want.
WhatsApp also provides a Default Message Timer for new individual chats. This means you can choose a disappearing-message duration as a default instead of enabling it manually every time.
However, disappearing messages should not be treated as a guarantee that something can never be saved. For example, a recipient may preserve information in other ways, and some quoted or backed-up content can behave differently.
Think of the feature as a privacy and clutter-control tool, not a magic delete button.
3. Use Advanced Chat Privacy for Sensitive Conversations
This is one of the less obvious privacy settings that many ordinary users may overlook.
Advanced Chat Privacy gives participants additional control over how information from a particular conversation can be shared outside WhatsApp.
When it is enabled, WhatsApp says participants cannot automatically save media from that chat to their device gallery, export the chat, or ask Meta AI to answer questions or create images or summaries using that chat.
The setting can be used in individual and group chats. In an individual conversation, either participant can enable it. In a group, an admin can enable it.
When should you use it?
It can make sense for conversations containing:
- Personal information
- Sensitive family discussions
- Private plans
- Work-related information
- Information that you do not want easily exported or reused
You can usually find the setting inside the chat information screen under the privacy-related options.
It is particularly useful when you want more control over a conversation without having to lock the entire WhatsApp application.
4. Silence Calls From Unknown Numbers
WhatsApp calls can be useful, but unexpected calls from unknown numbers can also become annoying.
WhatsApp includes a Silence Unknown Callers feature that prevents calls from unknown numbers from making your phone ring. The calls can still appear in your Calls list and notifications, so you can check them later if necessary.
How to enable it
Go to:
WhatsApp → Settings → Privacy → Calls → Silence Unknown Callers
This is especially useful if you frequently receive spam calls or calls from numbers that are not saved in your contacts.
There is an important difference here: the feature does not completely erase the call. Instead, it prevents the phone from ringing while keeping the call visible in your call history.
That makes it a good balance between convenience and privacy.
5. Mark a Chat as Unread Even After Opening It
Have you ever opened a WhatsApp message while busy and then forgotten to reply?
The Mark as Unread option can help with that.
When you mark a chat as unread, WhatsApp puts the unread indicator back on your side. It acts as a reminder that you still need to return to the conversation.
There is an important detail, though: marking a chat as unread does not undo the read status for the sender. In other words, the other person can still see that you read the message if read receipts were available.
How to use it
On supported devices:
- Find the conversation in your chat list.
- Open the chat options.
- Select Mark as unread.
This is a simple feature, but it can be surprisingly useful if you receive a lot of messages every day.
6. Edit a Message After Sending It
Everyone makes typing mistakes.
Maybe you sent the wrong word, made a spelling mistake, or realized that your message needed a little clarification. Instead of deleting the message and sending another one, WhatsApp lets you edit sent messages.
WhatsApp originally introduced message editing with a 15-minute editing window after sending. Edited messages are marked as “edited,” but WhatsApp does not show an edit history to the other person.
How to edit a message
- Press and hold the message you sent.
- Select Edit.
- Correct the text.
- Save the edited message.
This is particularly useful in work chats and group conversations, where sending several correction messages can make a conversation unnecessarily confusing.
One thing to remember is that editing is for correcting or updating your own message. It is not a way to secretly change what someone else sees without any indication—the edited label remains visible.
7. Keep Important Chats at the Top
If you have dozens or hundreds of WhatsApp conversations, finding an important chat can become frustrating.
WhatsApp lets you pin chats so they remain near the top of your chat list. According to WhatsApp’s Help Center, up to three chats can be pinned.
You can use this for:
- Family conversations
- Work chats
- Important contacts
- Personal notes
- Frequently used groups
How to pin a chat
On your phone, press and hold the conversation and choose the pin option. On WhatsApp Web and desktop, the option is available through the chat menu.
Pinned chats are not locked or hidden. They simply stay easier to find.
If your chat list is crowded, this small feature can save you time every day.
8. Free Up Storage Without Deleting the Whole Conversation
WhatsApp can consume a surprising amount of phone storage, especially if you are part of active groups that constantly share videos, photos, and documents.
Instead of deleting an entire conversation, WhatsApp provides tools that let you manage large files and remove unnecessary media.
WhatsApp’s newer storage controls allow users to find and delete large files directly within chats. You can also clear media while keeping the chat history itself.
A simple way to use it
Open the relevant chat and look for its storage or media-management option. From there, you can review larger files and decide what you actually need.
Before deleting anything important, check the file carefully. A large video may be taking up space, but it could also be something you want to keep.
This approach is better than randomly clearing WhatsApp data because you remain in control of what gets removed.
9. Use the Same WhatsApp Account on Multiple Devices
You do not necessarily have to use WhatsApp on only one phone or one computer.
WhatsApp supports linked devices, allowing the same account to be used across multiple supported devices. WhatsApp says you can link your primary phone with up to four additional devices, although the primary phone needs to be used periodically to keep linked devices connected.
You can also use the same WhatsApp account on a second phone as a companion device.
How to link another device
On your primary phone:
WhatsApp → Linked Devices → Link a Device
Then follow the instructions shown on the second device.
This can be useful if you have a personal phone and a second device that you regularly use.
A security tip
Do not forget about linked devices.
Occasionally open Linked Devices and check whether every connected device belongs to you. If you see something you do not recognize, remove it.
This is one of those settings that takes only a few seconds to check but can be important for account security.
10. Protect Your Account With a Passkey
Passwords and verification codes are not the only way to secure your WhatsApp account.
WhatsApp now supports passkeys, which can allow you to authenticate using your fingerprint, Face ID, or device screen-lock method, depending on your device. WhatsApp announced in August 2026 that more than one billion people were using passkeys on WhatsApp.
WhatsApp also says users who use both Android and iOS devices can add more than one passkey to their account.
Where to find it
Go to:
WhatsApp → Settings → Account → Passkeys
If the option is available on your account and device, follow the on-screen instructions.
Passkeys are useful because they reduce dependence on manually entering authentication information and use security already built into your device.
You should still keep your phone’s screen lock secure. A weak device PIN can undermine the protection of other security features.
11. Make Your Chat Backups More Secure
End-to-end encryption protects personal WhatsApp conversations while they are being exchanged, but backups are another part of the picture.
WhatsApp offers end-to-end encrypted backups, providing an additional layer of protection for backed-up chat history. WhatsApp has also introduced passkey-based encryption for chat backups, allowing supported users to use a fingerprint, face recognition, or screen lock rather than remembering a separate password or long encryption key.
You can find the relevant option under:
Settings → Chats → Chat Backup → End-to-end Encrypted Backup
Availability and setup options may vary by device and account.
If your WhatsApp contains years of personal conversations, family photos, work messages, or important documents, it is worth checking how your backup is protected instead of assuming that every backup setting is automatically configured exactly the way you want.
12. Turn On Stronger Two-Step Account Protection
Two-step verification adds another layer of protection to your WhatsApp account.
WhatsApp has recently strengthened this system. In its August 2026 security update, WhatsApp said two-step verification was being upgraded from the traditional six-digit PIN to a longer password that can include letters, numbers, and special characters.
If the stronger option is available on your account, take advantage of it.
The basic idea is simple: your WhatsApp account should not rely on only one authentication step.
Good security habits
Use a password that is:
- Unique
- Difficult to guess
- Not based on your name or birthday
- Not reused on other important accounts
Never share your WhatsApp verification code or security credentials with another person, even if they claim to be from WhatsApp.
Scammers often try to create urgency. Taking a few seconds to verify what is happening can prevent a much bigger problem.
13. Check Privacy Settings With Privacy Checkup
WhatsApp has a feature called Privacy Checkup that helps users review important privacy settings in one place.
Instead of searching through different menus individually, Privacy Checkup guides you through several privacy controls covering areas such as messages, calls, personal information, and who can contact you.
Why this matters
Many people install WhatsApp, choose a few settings, and never look at them again.
But your preferences can change. You might have started using WhatsApp for work, joined new groups, or begun receiving messages from people you do not know.
A quick privacy review can help you understand what information you are sharing and who can reach you.
If you have never checked your WhatsApp privacy settings, this is a good place to start.
14. Try Strict Account Settings if You Need Stronger Protection
This is not a setting that every WhatsApp user needs, but it is worth knowing about.
Strict Account Settings is designed for people who may be at higher risk from sophisticated cyber attacks. WhatsApp describes it as a lockdown-style security feature that applies more restrictive privacy and security controls.
When enabled, it can make changes such as:
- Turning on two-step verification
- Turning on security notifications
- Encouraging end-to-end encrypted backups
- Turning off link previews
- Blocking high volumes of messages from unknown accounts
- Restricting certain profile information to contacts
- Limiting who can add you to groups
WhatsApp specifically says that most people are not targeted by the type of sophisticated attacks this feature is designed for.
So this is not something you necessarily need to enable just because it exists.
It is better viewed as an advanced security option for people with a genuine reason to use stronger restrictions.
15. Verify Your Security Code for Sensitive Chats
There is one more security feature that many regular users rarely think about: security code verification.
End-to-end encrypted one-to-one chats have a unique security code. WhatsApp explains that this code can be viewed as a QR code or a 60-digit number and can be compared between the two people in the conversation.
The purpose is to help verify that the encrypted connection between you and the other person is legitimate.
Security codes can change, for example, if someone reinstalls WhatsApp, changes phones, or adds or removes a linked device. A change does not automatically mean that something malicious has happened.
For normal everyday chats, most people will never need to manually compare security codes.
But for particularly sensitive conversations, knowing that this verification option exists can be useful.
Bonus: WhatsApp’s Newer Features Are Worth Watching
WhatsApp is adding new features regularly, so the app you use today may not look exactly the same a few months from now.
For example, WhatsApp has recently introduced or announced features involving multiple accounts on iOS, improved storage management, cross-platform chat transfer, AI-assisted tools, sticker improvements, and other changes. Some features are rolled out gradually, meaning they may appear for some users before others.
In 2026, WhatsApp also announced Incognito Chat with Meta AI, a private temporary way to interact with Meta AI where conversations are not saved and messages disappear by default. WhatsApp said the feature was rolling out gradually.
That is a good reminder not to assume that a feature is available to everyone simply because you saw it mentioned online.
Always check your own WhatsApp app before following a guide.
Which WhatsApp Features Should You Enable First?
You do not need to change every setting at once.
For most users, I would start with these:
For privacy:
Chat Lock, Disappearing Messages, Advanced Chat Privacy, and Privacy Checkup.
For security:
Passkeys, stronger two-step verification, encrypted backups, and checking linked devices.
For convenience:
Pinned chats, Mark as Unread, message editing, and storage management.
For stronger protection:
Silence Unknown Callers and, where appropriate, Strict Account Settings.
The best settings depend on how you actually use WhatsApp. Someone who mainly chats with family may need different controls from someone who uses WhatsApp for work or receives messages from many unknown numbers.
Are These WhatsApp Features Available on Every Phone?
Not necessarily.
WhatsApp supports Android, iPhone, Web, Windows, and Mac, but individual features can have different availability depending on the platform. Some features are also introduced gradually by WhatsApp, so two users may not see exactly the same options at the same time.
For example, WhatsApp’s Help Center currently provides separate instructions for Android, iOS, Web, Windows, and Mac for several features.
If a feature mentioned in this article is missing:
- Update WhatsApp from your device’s official app store.
- Restart WhatsApp.
- Check the relevant Settings section again.
- Make sure the feature is supported on your device.
- Remember that some new features may be rolling out gradually.
Avoid downloading unofficial modified versions of WhatsApp simply because they claim to provide features that are not available in the official app.
Is WhatsApp Actually Private?
WhatsApp uses end-to-end encryption for personal messages and calls by default. WhatsApp’s Help Center explains that personal messages, photos, videos, voice messages, documents, live locations, status updates, and calls are protected by end-to-end encryption.
However, privacy is not simply about encryption.
Your device can still be accessed by someone who knows your screen lock. Notifications can expose information if you allow message previews. Linked devices can provide access to your account if you leave an unauthorized device connected. And information you voluntarily share can always be seen by the people you share it with.
That is why features such as Chat Lock, passkeys, privacy controls, encrypted backups, and linked-device management matter.
Good digital privacy is usually the result of several small habits rather than one magic setting.
Final Thoughts
WhatsApp is much more than a simple messaging app. Behind the familiar chat screen are privacy controls, account-security tools, storage management options, device-linking features, and several small conveniences that can make the app easier to use.
Some of the features in this list, such as Chat Lock and disappearing messages, are focused mainly on privacy. Others, such as message editing and pinned chats, are simply designed to make everyday communication easier. Security features such as passkeys, encrypted backups, and two-step verification are especially worth reviewing because your WhatsApp account can contain years of personal information.
You do not have to enable everything.
Start with the features that solve a real problem for you. Check your privacy settings, review your linked devices, secure your account, and keep WhatsApp updated.
And remember: WhatsApp features change over time. If a setting looks different on your phone, that does not necessarily mean the guide is wrong. WhatsApp regularly updates its apps and gradually rolls out new features, so the exact menus can vary.
The most useful WhatsApp feature is ultimately the one that makes your daily communication more private, more secure, or simply easier.
