Whatsapp, in a recent update, introduces new 2-Step verification to increase the security. This also fixed the security loophole to prevent the hackers from hijacking your account with knowing your number and some hacking techniquie.
WhatsApp allows users to sign up to the app using their phone number, so if an attacker wants to hijack your WhatsApp account, they would require an OTP (One time password) send to your phone number.
The attacker can grab this OTP by diverting the SMS containing the passcode to their own computer or phone, using either a malicious app or SS7 vulnerability, and then log into the victim's WhatsApp account. The attack even works in case the phone is locked.
In order to fix this issue, Whatsapp introduces 2-step verification password feature for android and iPhone. User can set their 6 digit password to secure their Whatsapp.
How To Enable 2-Step Verification
To enable 2-Step verification first log in to your Whatsapp account and follow these step.
- Go to WhatsApp Settings → Account → Two-step verification.
- Click enable, set a 6-digit passcode and re-confirm it.
- On next screen, enter your email ID (optional) to enable passcode recovery via email. (It's recommended to use email as backup so that you're not locked out of your account if you forget your passcode.)
- Hit "Done, " and you are all set to go.
