Two-factor authentication is gradually becoming the medium of choice for most cloud services. In this modern day, when phishing attacks are highly uncommon and your entire professional and personal information is linked to your devices; it is only common sense to add an additional security blanket to prevent any hostile activity from taking place.
Cloud services house enormous amounts of your personal and professional data and it is too great a risk to have your cloud credentials compromised. Since most people opt for easy passwords which that are prone to hacking. Hence, many cloud services now opt for additional security in the form of two-factor authentication.
In present day, if a hacker can gain access in your personal email or cloud service, then he can commit a variety of offenses ranging from espionage to subtle prank messages. The solution to this entire ordeal lies in opting for a two-factor authentication especially ones that house incredibly sensitive information.
In two-factor authentication, it is required that when signing in from any unrecognized device, the user has to submit a secret code which is usually received in either the form of a text message or is generated through an authenticator app on a previously registered smartphone. When deciding an authenticator application, you can choose from a multitude of services, all of which follow the same standard in generating a limited-time based one-time password.
Some of the cloud services now allow you to choose the methodology that you want to subscribe for the two-factor authentication while others have it set by default.
In order to use two-factor authentication, you need to choose the service that you desire to protect. Once chosen, you need to associate your account to a trusted device. This could be done by either linking a phone number or through scanning a barcode. The phone number that you desire to link will receive an authentication code which has to be entered in your account. Whereas, the barcode method requires scanning the code through your smartphone which would establish the device as trustworthy.
Now if a thief is using phished credentials, then he will be out of luck because he would lack the method of retrieving the one time code which establishes the device as trustworthy and allows sign in.
Even though, the two-factor authentication increases the hassle, however it is just for the first time and isn’t your personal data worth going through that minute hassle?
