There is no official way to know if two persons are chatting on WhatsApp. However, you can try some methods to find out their online status and activity, such as calling them, using WhatsApp web, or using monitoring apps.
To see who someone is talking to on whatsapp is easy with the help of third-party WhatsApp spy apps like KidsGuard WhatsApp Reader. You would need to access the target device one time to install this app on it after which the app goes incognito on the target device.
Online means that contact has WhatsApp open in the foreground on their device and is connected to the Internet, which means they are active on the WhatsApp app. The online status, however, does not necessarily mean that the person has read your message.
Do you want to send the same message to multiple people on WhatsApp? To send a message to multiple contacts individually without adding them to a group, you can create a broadcast list. Or, if you want all of the recipients to be able to chat together, you can add up to 256 contacts to a group chat.
On Android, tap the ellipsis icon (three dots) at the top right and select “Linked Devices.” Then, tap the “Link a device” button on the next page to start the process to use same WhatsApp account on two phones.
What 'last seen' means on WhatsApp. If you're in a one-on-one conversation with someone on WhatsApp, you might see a message at the top of the screen that says last seen at. This message shows you the last time that the person you're chatting with logged into WhatsApp.
Open WhatsApp and tap the settings option at the top of the screen. Tap privacy and tap last seen. There are three options here; nobody, everyone, my contacts. Select nobody to hide WhatsApp online status while chatting.
Read in incognito mode or go offline
If you are using WhatsApp for desktop then switching to incognito mode will let you see someone's WhatsApp status without letting them know.
However, you can look for signs indicating he is chatting with someone else, such as being online frequently, hiding his last seen or read receipts, changing his profile photo or status, or being secretive about his phone.
3mSpy Phone Monitoring App
mSpy is another app that features a super-advanced algorithm to help you monitor every tap or keystroke from another phone. You can easily see who someone has been talking to and what he has been talking about lately, be it through calls or messages.
The explanation(s) if you see somebody coming 'online' for just a few seconds on WhatsApp are: They opened the app to read a message without replying, then closed the app.
Hide Your Status
Go to Settings >> Account >> Privacy >> Status and set it to “Nobody”.
Most people using the app open it 23-25 times daily. They use it to stay in touch with friends and family. But other than that, Whatsapp is also a hotspot for finding potential love interests. The platform's prominence makes it a ripe target for online dating scammers, a.k.a romance scammers.
Your ex might be seeking information about what's happening in your life. They no longer have access to you as they did before, so they can't exactly ask you what you've got going on. So, they'll check your status updates or ask those who still have you on WhatsApp to check on you instead.
The biggest disadvantage of using Whatsapp is that, the last time you had logged in to the the messaging app is publicly visible to anyone. This is a serious problem as other people can easily keep a track of your logging in and out of Whatsapp, thereby, your whereabouts.
What is this? WhatsApp does not show how many times you viewed a status. If someone on your contact list posts something on their WhatsApp status, you can view it as many times as you want. They will only see that you have viewed their status, but WhatsApp does not reveal the number of times you did.
Each linked phone connects to WhatsApp independently, ensuring that your personal messages, media, and calls are end-to-end encrypted, and if your primary device is inactive for a long period, we automatically log you out of all companion devices. Linking phones as companion devices makes messaging easier.
In Short. Companion mode will enable users to link their current WhatsApp account to another mobile device. Currently, the companion mode on WhatsApp for iOS is not accessible, so the second device must be an Android phone or tablet.
iPhone users can use two WhatsApp accounts with the help of WhatsApp Business. It is an official business-oriented version of WhatsApp. This version offers all the features available in the regular version. The business version comes with features like auto-replies and catalogues.
