The way security keys work is that you go to login to the resource in question and when you go to login it asks you for a second factor of authentication – in this case the security key. You push a button on your security key and it displays a number which you then type in and you gain access to your resource.

This kind of authentication should be used more frequently in my opinion. Anyone can look over your shoulder and see your password, or guess your password if it’s a week password using social hacking but with a security key you really up the level of security for yourself.

I encourage people to use two factor authentication, not just with your PayPal but to try and implement it with other resources that you need to secure in your networks.
