Facebook Account Security has just gotten better and sophisticated through a much awaited move. Facebook has done this by bringing forth a new security feature today for the security enthusiasts. Many people did not find the two-factor authentication system via SMS and the app generator quite convenient all the time, hence Facebook went ahead with this step.
Now you can secure your account with a device that is inserted in the USB port of your laptop. This device commonly referred to as a USB security key is a small pen drive lookalike which acts as the new 2nd factor of authentication for your accounts. You will still need to enter your password as usual on the login screen but without this USB key, you cannot log in. You can get through the authentication process just by a tap on the key. To add the key to your Facebook account, you will need to go to
Settings > Security > Login Approvals > Security Keys
Interoperability being one its major feature, the key can be used to manage account security for various platforms such as Github, DropBox, Gmail etc.
Where to Buy the Key for Account Security
One such key is available for purchase on Amazon India. Many other versions of key are also available on Amazon. The basic key allows you to login directly with a tap and can be purchased here. The advanced version adds further security to your account such as the OTP functionality, dual slots on OpenPGP and OATH etc. That is all the technical lingo. For now, these higher variants are not recommended for a new user. If you are interested in taking the next step for your security, you can start with the initial variant. You can make the purchase based on your needs and extent of security you need for your accounts. Moreover also consider the kind of data that you are trying to protect.
