Dimon: 'You don't want rogue agents, and there could be thousands of them'

The crackdown started last week on JPMorgan's earnings call, where CEO Jamie Dimon said the bank would not let unvetted outside agents into its systems. CFO Jeremy Barnum warned customers who hand over their logins carry the risk themselves.

Most banks are moving toward read-only agent access — agents can see balances but not move money. At Charles Schwab, CEO Rick Wurster said the brokerage blocks big unauthorized agents, including Meta's Muse, 'in the tens and 20s' each week.
