So what's the solution?
If the hacked WhatsApp account uses a telephone number, we can verify the telephone number by entering the 6-digit code received via SMS. After entering the 6-digit SMS code, hackers using our WhatsApp account will be automatically kicked out.
You may also be asked to enter a two-step verification code. If we don't know the code, the person using our account may have two-step verification enabled. Like it or not, we have to wait 7 days before being able to log in to an account without a two-step verification code.
Whether or not we know the verification code, hackers who use our WhatsApp account will be issued after we enter the 6-digit SMS code. After that, if we already have access to the account and suspect that someone is using our account via WhatsApp Web/Desktop, we recommend removing or terminating the WhatsApp account connection on all computers connected to that account.
After that, to prevent WhatsApp accounts from being hijacked, all you have to do is activate two-step verification. When we activate this two-step verification we will be asked to enter a six-digit PIN. The function of this PIN is as entry access when changing cellphones in the future.
The way to activate two-step authentication (Two Step Authentication) is as follows. First of all, enter the WhatsApp profile then select Settings (Settings). After that, select Account (Account) and click two-step authentication (Two Step Authentication). Next, activate this feature by entering a six-digit PIN.
After the two-step authentication (Two Step Authentication) is active, enter a six-digit PIN when logging in to a different device or gadget. Apart from that, every now and then we will also be asked to enter this six-digit PIN on the device or gadget that we are currently using.
