DSP2 is a strong authentication method that allows you to validate an online transaction over 30€ by directly connecting to your bank account. This system replaces the 3DSecure system, which only required entering a one-time unique code received via SMS to validate the payment.
Today, for enhanced security, you need to validate the transaction using:
A password and secret code that only you know
Your mobile phone with your bank’s application
A biometric characteristic (fingerprint, voice recognition, facial recognition)
