VIABUY Authenticator

Dock Financial

About this app

​​With the VIABUY Authenticator, we are introducing a new way to approve online transactions for all VIABUY customers. Similar to entering an SMS one-time password when doing a bank transfer, you may be prompted to confirm certain online payments from time to time.
You can now authenticate transactions directly with our new VIABUY Authenticator app instead of SMS.

The VIABUY account with a prepaid Mastercard card is an independent alternative to traditional bank accounts with debit or credit cards.
