    Credit card company: "We need to send you a one-time passcode to process your charge!" Me: "okay" Rep: "What's the number we should send it to?" Me: *what kind of verification is it if I provide the number?!* Rest of brain: "SHUT UP AND GET IT OVER WITH" Me: "Pls text me at..."

        Also, the text even calls it "OTP"—abbreviated, with no explanation. Programmers are designing user-interface and non-security people are designing the verification process...

        I remember another "verification" process triggered after I logged on to ATM with Apple Wallet card. ATM prints slip saying call this number. At the number, automated system says enter the text we just sent. HELLO. I used the phone's NFC. I HAVE THE PHONE! I CAN READ ITS TEXTS.

        Brought to you by the people that make you sign your new credit card in front of them and then compare it to your signature on the receipt you also just signed.

        My bank recently went from using phisical card for 2fa (numbers on card in grid, each operation would ask for 3 coordinates) to a 30 second code provided by an app on the same phone. I feel it's a downgrade, I could keep the card and phone separate, but now...

        I bought an expensive thing with a credit card. The company I bought from (not the CC company) called me to ask verification questions. One was "What's a major highway near you". I thought "Well, I just gave you my address, and I'm at my computer, so I could check Google Maps.".

        What I actually said was something like "I just moved here, and I don't drive so I don't really know. Oh, yeah, I walk under a major highway every day, I-70". They let the purchase happen. The major highway I walk under every day is not, in fact, I-70.

        I had the opposite experience, I wanted to link google pay to my bank account but even after answering to all security questions they would have to send me a code over SMS/phone. I couldn't since I was using another SIM card

        Bank: For security, please tell us at which branch you opened your account. Me: I never opened an account with you. Y’all bought my bank and shut it down. Bank: Thank you; that is the correct answer.

        I'm sorry about that. I was arguing to the functional analyst and the security architect that it didn't make sense, but they ignored me. Maybe they just wanted to collect phone numbers. (* True story, though probably not your bank ;) )
