These days you cannot be too careful when it comes to online security and protecting your clients' accounts. Where once the use of nothing but a username and password were more than enough to secure an online account, these are readily hackable as most people use easy to remember information. By adding another identifier to the mix you are creating a two factor authentication system that is virtually impossible to hack.
The online gaming industry has long been the target of hackers who will hack into a person's gaming account, use it to make as much in game currency as possible that can be sold on the web for real cash and then move on once they have been discovered. In light of this the top online gaming sites now use the two form authentication system to protect player's accounts. For more information on this type of security, contact us at Digi-Sign.
