WhatsApp is a mobile messaging app for your smartphone that allows you to send text messages, photographs, videos and audio. With more than a billion people using WhatsApp, it is not surprising that it has become attractive to scammers seeking to use its popularity to lure people into becoming scam victims. Also, like many popular apps, it has been a target of hackers seeking to take over the accounts of legitimate users of the app and send out malware filled messages that appear to be trustworthy because the messages look like they are coming from someone the victim trusts.
Mere passwords have not proven to be a particular secure method of authentication. Many people use simple to guess passwords and even what may appear to be complex passwords can often be identified by sophisticated hackers using password cracking software. However, more and more companies such as Facebook, Twitter, Google, Tumblr, Yahoo and others are using dual factor authentication by which when your password is used to access you account, a special code is sent to your smartphone that must be used in order to complete access to the account. This provides dramatically enhanced security. Now WhatsApp has become the latest app to offer dual factor authentication.
Passwords are just too vulnerable to be the sole method of authentication for important apps or accounts. Whenever you are able to use dual factor authentication for a particular website, account or app, you should take advantage of this. Some dual factor authentication protocols do not require it to be used when you are accessing the account from the computer or smartphone that you usually use, but only if the request to access the account comes from a different device, which still provides security without even having to use the special code.
