Banks warn customers not to give AI agents account logins
First merged summary.
Major US banks are warning that customers who share logins with AI agents stay liable, and many are steering tools toward read-only access.
Bank of America emailed customers titled “Protecting your finances in the Al World,” telling them never to share a username and password with a person or outside service, including an AI tool or agent that offers to act for them. The bank says account holders remain responsible for activity that follows from that access. According to Axios, as reported by Malwarebytes, major US banks are detecting third-party AI agents inside customer accounts, often using logins customers supplied. JPMorgan Chase CEO Jamie Dimon said allowing arbitrary outside agents was too risky. Many banks allow or are moving toward read-only access so tools can analyze transactions without moving money. TechCrunch says banks are still working out agentic payments; Bank of America did not immediately comment.
