Major U.S. banks block AI agents that log in with customers' credentials
Several major U.S. banks are blocking AI agents that access accounts using a customer's login credentials, saying their terms require human access. Bank of America has asked customers not to give their banking passwords to AI assistants.
Who is affected and how
- retail customer
- Banking passwords and login details should not be given to AI assistants, because the bank prohibits it and the activity is hard to trace.
- banking professional
- Banks already struggle to tell whether the account owner or an AI agent is carrying out an action, so identifying agent traffic is an urgent task.
- fintech company
- Agent products built on sharing customers' credentials rest on a risky business model; official API access is needed.
