Bank of America warns customers not to share their banking password with their AI assistant
Bank of America emailed customers under the title "Protecting your finances in the AI world," asking them not to share their username and password with anyone, including "an AI-enabled tool or agent that offers to act on your behalf," and noting the customer remains responsible for any activity resulting from such access. The warning comes as more users hand their credentials to personal AI assistants, while banks globally are already reporting incidents of unauthorized AI agent access to customer accounts, as the industry still works out how to safely allow "agentic payments," purchases an AI tool makes on a user's behalf. The risk, as the bank describes it, cuts two ways: either the assistant acts without the user's full knowledge, or a security flaw in the AI tool itself leaks the credentials to malicious third parties. For a business or professional considering linking a personal AI assistant to a bank account, the warning shows that banks themselves consider the risk serious enough to actively notify customers, before any single standard for secure access even exists.
