IBAN stands for International Bank Account Number, a standardized code used to identify individual bank accounts during cross-border payments. It acts like a detailed postal address for your money, ensuring funds reach the correct recipient by including the country code, bank details, and your specific account number.
While often confused with a SWIFT or BIC code (which identifies the bank itself), the IBAN pinpoints the exact account. It is widely used in Europe and over 70 other countries to reduce errors and speed up international transfers.
That sounds like the autofill/payment-method prompt rather than the normal password prompt. As a workaround, check Settings → Autofill and passwords → Payment methods and see if saving/filling payment methods can be disabled there; that should leave password saving separate. I agree a per-site or “never for IBANs” option would be cleaner, because bank account numbers are not the same kind of secret as a login but they are still sensitive enough that repeated prompts are annoying.
The first one is the relevant switch: “Save and auto-fill payment methods”. That is the feature that offers to save card/bank-payment data. The CVC setting is only for card security codes, and “Allow websites to access your saved payment methods” is about sites detecting already-saved methods, not about the save prompt itself. If you only want password prompts, I would turn off the first payment-method toggle and leave password saving enabled separately.
