Hi Deriv Community Members, 
If you received a deposit error as “Authentication failed” upon depositing via Mastercard or VisaCard, it shows that your debit/credit card 3-D Secure authentication was not complete.
Thus, please ensure you enter the correct security code from MasterCard (called SecureCode) or Visa (called Verified by Visa). And you may contact your bank for more information if you don’t receive the code or the code shows invalid.
Hope this information finds you well 
If you have any questions, please visit our Help Centre or contact us via Live Chat and WhatsApp.
