Due to security reasons, you only have three attempts before your Gold Card becomes unsynchronized with the verification system. You will then be asked to resynchronize the Card. By following the normal login process, a new window will appear that requests you to enter two consecutive Security Codes in order to resynchronize with the verification system.
If you fail to synchronize your Gold Card, please generate two consecutive Security Codes with your Gold Card and add these in a Support Case sent to the Entropia Support. Please do NOT generate any further codes until the support staff has confirmed that your Gold Card is synchronized.
