How does PSD2 affect bank customers' digital identity?

BBVA, for example, use the same model that Consult Hyperion has been using with its clients to help them think through their strategies.

Authentication: verification through credentials that the user is the customer they say they are (username and password, OTP, digital certificates and others). 

Authorization: the financial service providers (TPP) with a license to operate must be given authorization by the customers before they can access their accounts. They need to have proof of consent, which can be obtained through access tokens. "

The report also described how gangs stole mobile security codes – which banks automatically send to card holders’ registered mobile phones to verify online transactions – by using either a Trojan...
