If your talking about the online authentication for Unl. Members trainers. You can down load an offline authentication code unique to your account on the trainer page. This tells the trainer that your account is in good standing order and has not been banned. And allows you to use them offline.
Q: I'm an Unlimited member and trainers that I download say they must be authenticated before they can be used. What's this about?
A: Authenticity checks were added to our personalized trainers in an effort to maintain the integrity of files downloaded from our site and to also help curb illegal file sharing. If an Internet connection is present and the trainer is not being blocked by a firewall or security application, this check will be transparent. If an Internet connection is not present or the trainer is blocked, an offline key will be needed to run the trainer. A key can be obtained from our trainer troubleshooting page. Please note that no information, personal or otherwise, is sent to Cheat Happens during the online authenticity check. Your trainers will fail this check if your account has been banned. This check does not apply to PROMO or PUBLIC trainers, only those personalized for individual use.
