YubiKey is the latest Facebook offering to increase the level of user account security. This is a hardware key that effectively protects it from hacker attacks.
Increasing threat from hackers has forced companies to provide different types of Internet services, increasing the level of security of user accounts.
Most of them went to a two-tier user authentication system, consisting of a password and an additional code sent by SMS to his phone. This way, even if a cybercriminal steals passwords, he will not take over our account as he will not have access to the second security code.
This has been the case so far, but more and more tools are emerging to take control of the victim’s smartphone and thus get access to authorized SMSs, so the two-tier security system is no longer so secure. Facebook has this way in the form of an external hardware key called YubiKey.
