Activation for MasterCard SecureCode is now automatic and registration is no longer required for Southside Bank debit cardholders.  If a transaction is presented to the bank for authorization where the transaction details do not match what we have on record, you may be required to authenticate the transaction using a One Time Passcode (OTP) that will be sent to the mobile number that is on file.
