Yes, I always do that. I'm a security freak
Greetings from Alto Adige (Südtirol)
These payments have been made directly with the credit card credentials, not through PayPal, Skrill or any other payment service. I have enabled Two Factor Authentication on every payment website (where possible).
Nexi Pay is the official app of the Nexi credit card institute (former CartaSi).
Thank you all for your advices.
Sincerely
ThoSap
