The socialbites.ca correspondent noted that in the latest beta versions of WhatsApp on Android, the possibility of using one account from several smartphones at once was discovered. Previously, this feature was only available for a group of smartphones and tablets running Android.
Thus, the user can log in to his main account on his second smartphone by downloading the beta version of WhatsApp for Android with the number 2.23.8.2 and above. To do this, on the number registration page on the second device, you must click on the three dots in the upper right corner of the screen and select the “Link to an existing account” option. Then you have to take the main smartphone, click the three dots on the WhatsApp home page, select the “Associated devices” section, and then scan the QR code that appears on the second smartphone.
Thus, users can simultaneously log into their existing accounts from several devices, including a PC, a tablet, and a second Android smartphone.
However, this innovation was only seen in the beta version of WhatsApp on Android. The emergence of a new feature in stable build and Apple devices has not yet been reported.
Previously cyber expert Bederov talked about his method of hacking WhatsApp using a QR code.
