WhatsApp’s new feature for linked devices and account security
WhatsApp is testing a new feature for linked devices, and it is an important security feature for your account security in 2026. WhatsApp's security tools already let you review linked devices, but the new feature could make your account safer by sending alerts when another device is active at the same time as your main phone. In simple terms, you would no longer need to keep opening the Linked Devices screen just to check whether something looks off.
This update was spotted in WhatsApp beta for Android 2.26.15.6, based on reports from WABetaInfo and follow-up coverage from other outlets. Right now, the feature is still under development, so you cannot use it yet. But the idea is easy to understand, and honestly, it makes a lot of sense.
What the new linked-device security feature does
At the center of this update is real-time monitoring for linked devices. Today, WhatsApp lets you see devices connected to your account, such as WhatsApp Web, a desktop app, or another companion device. That part already exists.
What is new is the alert system.
If you are using WhatsApp on your primary device and another linked device becomes active at the same time, WhatsApp may send a notification to your main phone. That means you get a heads-up right when concurrent activity happens.
A simple example helps here:
- You leave WhatsApp Web open on your office computer
- Later, you start using WhatsApp on your phone
- If that web session is active at the same time, WhatsApp may alert your primary device
That alert could help you spot unauthorized access faster instead of finding it hours later.
Why this matters for your account safety
This is a small change, but it can solve a very real problem. Many people do not check their linked devices often. You might scan a WhatsApp link device QR code once on a shared laptop, forget to log out, and move on with your day.
That is where risk starts.
At the moment, if your thought is, "My WhatsApp is linked to another device without me," you need to manually open the Linked Devices menu and inspect the session list. The new feature aims to cut that delay by warning you during simultaneous activity.
That matters because account safety often depends on speed. If someone is reading messages through an open web session, an instant alert gives you time to react before more damage is done.
How it is different from the current Linked Devices screen
Right now, WhatsApp gives you control, but not much urgency.
You can:
- Open WhatsApp settings
- Tap Linked Devices
- Review all active sessions
- Log out from devices you do not recognize
That works, but it depends on you remembering to check.
The upcoming system changes the flow. Instead of making you do all the checking, WhatsApp may notify you automatically when concurrent use is detected. According to the reporting, the alert will appear only on the primary device and only when another linked device is active at the same time.
That last part is important. WhatsApp does not want to flood you with pointless alerts. If you are only using a linked device yourself, a warning would not always be useful. The goal is relevance, not noise.
How to check linked devices on WhatsApp Android
Until this new feature rolls out, manual checking is still your best habit. If you want to know how to check linked devices on WhatsApp android, do this:
- Open WhatsApp on your Android phone
- Tap the menu icon or settings area
- Select Linked Devices
- Review every logged-in session
- Look for devices, browsers, or locations you do not recognize
- Tap a session and log it out if it seems suspicious
If something feels wrong, trust that feeling. A forgotten browser session is common. So is staying logged in on an old computer.
How to know if my WhatsApp is linked to another device
There is no single magic sign, but a few clues usually show up.
You may notice:
- Unknown devices in the Linked Devices list
- Messages marked as read when you did not open them
- Strange account behavior after using WhatsApp Web on a shared PC
- Security alerts or login prompts you did not expect
- Friends saying they got odd messages from you
If you keep wondering, "How to know if my WhatsApp is linked to another device," start with the Linked Devices screen. It is still the clearest place to verify active sessions.
Once WhatsApp launches this new security feature, that process should become easier because you may get notified during suspicious simultaneous activity.
WhatsApp is extending chat lock functionality to linked devices
This new alert system is not happening in isolation. WhatsApp is extending chat lock functionality to linked devices as part of its broader account security push.
Earlier beta reporting showed that WhatsApp had already been working on chat locks for companion devices. Before that, locked chats were mainly protected on the main device. The newer approach expands protection by letting users secure conversations on linked devices too, using a passcode or secret code system.
That is a helpful step because account security is not just about seeing who is logged in. It is also about limiting what another person can access if they get near one of your connected devices.
Put both updates together and the direction is clear:
- Better visibility into linked-device activity
- Better protection for sensitive chats
What happens if WhatsApp detects concurrent activity
Based on current reporting, the notification behavior is pretty specific:
- Alerts are sent only to the primary device
- Alerts happen only when simultaneous activity is detected
- The feature is expected to be optional through advanced privacy settings
This means WhatsApp is trying to alert you at the moment it matters most.
Imagine you left your laptop open at work. Someone clicks into your WhatsApp Web session while you are texting from your phone on the bus home. If the system works as described, your phone would get a warning. You could then check sessions right away and remove the device.
That is much more useful than discovering the issue days later.
How to secure My WhatsApp account from hackers
Even with the new feature coming, your daily habits still matter. If you want to know how to secure My WhatsApp account from hackers, start with the basics:
- Turn on two-step verification in WhatsApp
- Never share your SMS code or verification code
- Review linked devices often
- Log out of WhatsApp Web on shared or public computers
- Lock your phone with biometrics or a strong PIN
- Keep WhatsApp updated
- Use chat lock for sensitive conversations when available
- Be careful with phishing links and fake support messages
A lot of so-called hacking cases are really session misuse, QR linking on a trusted device, or social engineering. Someone does not always need to break into your phone. Sometimes they just need you to scan the wrong QR code once.
What to do if your WhatsApp account is hacked
If you suspect your account has been misused, act quickly.
Here is what to do if your WhatsApp account is hacked:
- Open Linked Devices and log out of every unknown session
- Reinstall or re-verify WhatsApp on your main phone if needed
- Enable two-step verification immediately
- Check for any changed settings or suspicious account activity
- Warn your contacts if strange messages were sent from your number
- Contact WhatsApp support if you cannot regain control
If you are searching for how to logout from hacked WhatsApp, the fastest route is usually through the Linked Devices section. Remove every device you do not trust. Then secure the account before linking anything again.
Also pay attention to a WhatsApp hacked message sent from your number. If friends tell you they received odd links, money requests, or urgent texts that sound unlike you, take that as a warning sign.
Rollout status and when you may get it
At the time of writing, this feature is still under development and not yet available for public beta testing. It was discovered in WhatsApp beta for Android 2.26.15.6 on the Google Play Store, but that does not mean it is live for everyone.
The expected rollout path is familiar:
- Development in beta builds
- Limited release to select users
- Wider rollout in a future update
So if you do not see it yet, that is normal.
What this means for everyday users
For most people, this feature is about peace of mind.
You should not have to constantly wonder whether an old desktop session is still open. You also should not need to manually check linked devices every day just to feel safe. If WhatsApp delivers these alerts well, the feature could become one of the most practical security updates the app has added in a while.
It will not replace good habits, but it can give you one more early warning sign. And for account safety, early warnings matter a lot.
FAQ
Are WhatsApp-linked devices safe?
Yes, in general, WhatsApp-linked devices are designed to be safe. Your personal messages, media, and calls are protected by end-to-end encryption. Each linked device connects to WhatsApp independently while keeping the same privacy and security standard users expect. That said, safe design does not remove human mistakes. If you leave a browser session open on a shared computer, another person may still access your account from that device.
Can I tell if someone is reading my WhatsApp on another device?
Sometimes, yes. You may notice unknown sessions in Linked Devices, messages marked as read that you did not open, or account behavior that feels unusual. The upcoming linked-device security feature could make this much easier by alerting you when another device is active at the same time as your main phone.
Can someone read my WhatsApp messages from a linked device?
Yes. If someone has access to a linked device, such as an active WhatsApp Web session or another connected companion device, they may be able to read your messages without using your phone directly. That is why checking linked devices and logging out of unknown sessions is so important.
What does it mean when your WhatsApp account is being registered on a new device?
It usually means someone is trying to activate your WhatsApp account on another phone or device using your number. This can happen when you are switching phones, but it can also be a warning sign of unauthorized access. If you did not request it, do not share any verification code, secure your account, and review your linked devices and security settings right away.
