It is often safe to block all those contacts with whom you are not safe.
With WhatsApp, people are always connected online, eventually increasing the number of messages being sent to close aides.
Recently Facebook CEO Mark Zuckerberg noted that WhatsApp recently crossed 1.5 billion monthly active users with people sending more than 60 billion messages every day. In such a scenario, no one knows how many photos put up as display pictures on WhatsApp will get saved by others. All people, who have your contact number, can see your WhatsApp status and pictures unless they are blocked. All contacts on your phone may not be your friends.
Cyber security expert Rakshit Tandon recently said that people often tend to save phone numbers of drivers, maids, watchmen and many other people who need not know what you are doing on WhatsApp. “It is often safe to block all those contacts with whom you are not safe. Especially, predators tend to observe children or women’s status and display pictures. Even if individuals are blocked on WhatsApp, they can always be contacted via phone or messages which are much safer,” he said.
Experts urge users to enable two-factor authentication, especially since the number of mobile robbery cases are high. Don’t be reactive in your security, always be proactive. While a Facebook account or an Instagram account can be recovered in three minutes, it takes up to 72 hours to recover a WhatsApp account. In such a scenario, enabling two-factor authentication becomes important.
According to WhatsApp, “When you have two-step verification enabled, any attempt to verify your phone number on WhatsApp, must be accompanied by the six-digit PIN that you created using this feature. Upon enabling this feature, you can also optionally enter your e-mail address. If you receive an e-mail to disable two-step verification but did not request this, do not click on the link. Someone could be attempting to verify your phone number on WhatsApp.”
