US banks reportedly block third-party AI agents accessing customer accounts amid security risks

One post says Morgan Stanley, JPMorgan, Bank of America and Citi have seen agents use customer logins, sometimes contacting call centers or acting beyond instructions. Another says banks are blocking or limiting agents and that no major losses had been confirmed as of October 23. Separately, a user says 1Password launched a service that asks for device approval before autofilling logins, without showing agents the password.
