We all know that securing an account with just a password isn’t as secure as it used to be. Nowadays, you may also be asked for a second authentication code before you could access an account. Nonetheless, the second authentication protocol could be breached by a sophisticated hack. To protect the second authentication protocol better, you now can purchase a physical security key to harden the second authentication protocol. This means without a physical key, the hacker would have a very hard time trying to access your account. For an example, they could hack the service which hosts your account to have an access to your account, but this could also be hard for the hacker if the service is well protected. Anyway, check out the video right after the break to see a physical security key in action.
