Major US banks are locking out AI agents that log in with customer credentials

Major US banks including Morgan Stanley and JPMorgan are blocking or restricting AI agents that use customer login credentials to access financial accounts. These institutions are concerned about unauthorized activity occurring when users grant agents permissions to manage their accounts. By limiting these tools to read-only access, banks aim to prevent potential security risks and account takeovers. This shift highlights a growing friction between automated personal assistants and traditional banking security protocols regarding third-party data access.
