4. How to manage multiple WhatsApp accounts on the same browser

Using multiple social media accounts, especially WhatsApp, at the same time is becoming more and more necessary for many people. As a freelancer, I need to separate my work with clients and my personal chats.

Similarly, businesses and marketing teams often have to run multiple brands, customer support channels, and promotional campaigns, resulting in the need to maintain separate WhatsApp accounts for each purpose.

However, regular browsers don't support this well. Most only allow you to log in to one WhatsApp Web session at a time. Trying to open multiple accounts using incognito mode or extensions often results in conflicts, automatic logouts, or session errors.

That is why Hidemium becomes the optimal choice. This is one of the best anti-detection browsers available today, allowing you to assign separate browser fingerprints to each WhatsApp account. This allows you to log in and manage multiple accounts on the same device without worrying about duplication or interruption.

How to Manage Multiple WhatsApp Accounts Using Hidemium:

1. Visit website Hidemium.io

2. Download and installHidemium application compatible with your computer operating system.

3. After opening the app, the main dashboard will appear with some sample profiles. Tap"+ Add Profile"in the right corner to create a new profile.

How to create a separate WhatsApp profile:

• Profile name: Replace “Profile 1” with a name of your choice, for example “WhatsApp 1”.

• Switch to tab Proxy.

• Select proxy type: Tick “Proxy”.

• Select the desired country location — for example “United States”.

• Press “Check Proxy” to confirm the new IP is working

• Press “Create Profile” to complete.

Once created, the “WhatsApp 1” profile will appear in the list and be ready to use. When launched, Hidemium will open a separate anti-detection browser corresponding to this profile.

Now, you just need to open WhatsApp Web on that browser and log in to your WhatsApp account as usual.

You can create additional profiles to log in to multiple WhatsApp accounts. All work in parallel without being logged out or affecting each other, helping you manage effectively and with maximum security.

5. Common errors when logging into WhatsApp Web and how to handle them effectively

When logging into WhatsApp on a browser, users often encounter a number of errors that disrupt the experience. Here are the issues I encountered and how I successfully resolved them.

5.1. Unable to scan QR code

This is a fairly common error. Even when holding the phone close to the screen, the QR code on WhatsApp Web is still not scanned. Through practical experience, I realized that the cause usually comes from: a blurry or dusty camera lens, low ambient light, or an unstable network connection.

A simple but effective solution is to clean the camera, move to an area with better lighting, and make sure the QR code is clearly visible and not too zoomed in on the screen. After adjusting these factors, the scanning process is quick.

5.2. “Session Expired” Message

This error often appears unexpectedly even when you think everything is working normally. The main reason is that you have left the WhatsApp Web tab idle for too long or your browser automatically deletes your login cookies.

The fix is simple: refresh the page and rescan the QR code with your phone. When using the Hidemium browser, I always enable cookies in each profile to ensure that the login session is persistent every time I visit again.

5.3. “Phone not connected” error

Several times, WhatsApp Web showed a device not connected message, even though my phone had a signal and was fully connected to Wi-Fi. This was mostly because WhatsApp on the phone was not synced or was not running in the background.

I fixed it by double-checking that WhatsApp was open and making sure the device had a stable network connection. If the problem persisted, I tried toggling airplane mode on and off quickly to reset the network. Also, when using Hidemium, I double-checked my network configurations to make sure they weren't blocking connections needed for WhatsApp to work.

7. WhatsApp Web FAQ

Below are common questions from users when using WhatsApp Web, answered based on practical experience, to help you understand and use it more effectively.

1. How to log in to WhatsApp Web?

Logging into WhatsApp Web is very simple, just follow these steps:

• Visit the page https://web.whatsapp.com using a browser on your computer or laptop.

• Open the WhatsApp app on your phone, select the QR code scanning feature.

• Scan the QR code displayed on your computer screen to connect your account.

Once you have successfully scanned the code, you can use WhatsApp Web to send messages as usual.

2. Is it possible to log in to WhatsApp using just a phone number?

No, friends can't log in whatsapp with just a phone number without going through the verification step. The system will send an OTP code via SMS or call to authenticate your identity. In addition, when logging in to a new device, you still need to use your main phone to scan the QR code.

3. Does WhatsApp limit the number of accounts on one device?

Yes. Each WhatsApp account is linked to only one single phone number. Therefore, you cannot use multiple WhatsApp accounts at the same time on one device without the help of a dedicated tool.

However, browsers that support multiple accounts like Hidemium can help you log in and use multiple WhatsApp accounts at the same time without getting logged out, conflicts or account lockout errors.

4. Is WhatsApp Web safe?

Basically, WhatsApp Web is quite secure thanks to end-to-end encryption. However, the level of security still depends on how you use it:

• Avoid logging in on public or shared computers.

• Make sure to log out after each session.

• Do not install extensions from unknown sources.

• Use a password or screen lock to protect your personal device.

To increase security when using WhatsApp Web, you can combine it with anti-detection browsers such as Hidemium – a tool that helps protect identity, separate login environments, and reduce the risk of being tracked or exposed to data.
