 October 31, 2018  Mohit Kumar Apple introduces a new privacy feature for all new MacBooks that "at some extent" will prevent hackers and malicious applications from eavesdropping on your conversations. Apple's custom T2 security chip in the latest MacBooks includes a new hardware feature that physically disconnects the MacBook's built-in microphone whenever the user closes the lid, the company revealed yesterday at its event at the Brooklyn Academy of Music in New York. Though the new T2 chip is already present in the 2018 MacBook Pro models launched earlier this year, this new feature got unveiled when Apple launched the new Retina MacBook Air and published a full security guide for T2 Chip yesterday.

Dual WhatsApp: How to use dual WhatsApp in a single phone

Posted by on
Image result for whatsappAlmost all Android smartphones today come with support for dual-SIM card slots, allowing users to use two different numbers on a single device. Officially you cannot use two WhatsApp accounts in one smartphone. However, companies like Xiaomi, Samsung, Vivo, Oppo, Huawei and Honor now offer 'Dual Apps' or 'Dual Mode' feature (the name may differ from brand to brand) which allows users to run two different accounts of the same chat app.

This means you need not carry two smartphones just to use two WhatsApp accounts. Wondering how? Here's a ready-to-use guide.

First, let's start with the name and location every manufacturer uses for this feature:

Samsung: Dual Messenger
Settings > Advance features > Dual Messenger

Xiaomi (MIUI): Dual apps
Settings > Dual Apps

Oppo: Clone AppsSettings > Clone Apps

Vivo: App cloneSettings > App clone
Asus: Twin appsSettings > Twin apps


Huawei and Honor: App TwinSettings> App Twin

Now, how to use Dual WhatsApp feature on your smartphone.

1.

Open the dual apps settings option on your smartphone

2.

Select the app you want to duplicate (in this case select WhatsApp)

3.

Wait for the process to finish.

4.

Now, head to the home screen and tap on the second WhatsApp logo you see in your app launcher

5.

Configure using another phone number and get going.


Do note that there are a few phones -- Android one devices and those offering 'stock' Android -- that do not come with dual app features . For these, there are several apps such as Parallel, Dual App Wizard, DoubbleApp and more available on Google Play Store. Users can just download these apps to run two accounts of the same Chat app on their phones.
