Security clueless on the front end for sure. I asked the local bank teller to show me how the app worked with the different reference numbers they had given me. They were very patient, as was I, until it came to the password reset step. I was literally wtf are you kidding me when they told me to put in a password. You know, something like Juanmadrid2024.
