According to reports, customers are handing banking usernames and passwords to AI assistants, which can break rules that customers log in themselves.

Restricting agents

• Morgan Stanley
• JPMorgan Chase
• Bank of America
• Citigroup

Several large banks have started restricting third-party agent access.

Banks also worry about who is liable if an agent causes harm, and Charles Schwab's chief executive wants a daily report on blocked agents.
