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

AI brief

Customers are allowing AI agents to use their credentials to log into accounts at Morgan Stanley, JPMorgan and other major U.S. banks, sometimes without direct instructions. Morgan Stanley has blocked such agents, and other banks are restricting access.

Why it matters: Banks are limiting agent-driven logins as customers hand their account credentials to AI tools.
