We daily read about security breaches going around the world. This is the reason that many of the users have now started using 2 step verification for their social accounts. However, when we talk about WhatsApp then very few users show their interest in enabling 2-step verification process. As, according to them, WhatsApp account is associated with their phone number, therefore cannot be compromised. So, guys if you too feel the same then let me end your myth.
Just, think for a second if your phone gets stolen or someone issues a duplicate sim card by blocking your original sim, and insert that sim in his phone then he can easily get access to your WhatsApp.
However, if you have 2-step verification enabled then he needs that secret code before logging into yours WhatsApp account.
To get started you have to first start WhatsApp on your phone.
Also, WhatsApp tries to make you remember the PIN, therefore it will periodically ask you to enter your PIN. Also, you have no option to disable that without disabling the 2-step verification feature.
