Bank of America Warns Customers Not to Share Banking Passwords With AI Assistants
In an email to customers, the bank says anyone who hands login details to an AI agent is responsible for what that agent does.
Bank of America has emailed customers a warning about AI tools, according to TechCrunch. The email, titled "Protecting your finances in the AI World," tells people not to share their username and password with anyone or any outside service, including an AI tool or agent that offers to act for them. A bank spokesperson confirmed to TechCrunch that the email is real.
TechCrunch lists three risks. An assistant could take actions on your finances that you do not know about. Your bank may read the activity as an intrusion and lock you out. And a security flaw in the assistant could leak your credentials to attackers.
The email is blunt about responsibility: if you share your credentials, you are responsible for activity that results from that access. TechCrunch notes that most bank account agreements already work this way.
The article adds that banks, payment providers and processors are still working out how AI agents should fit into finance, including "agentic payments," where an agent buys things on your behalf. It does not describe any approved way to connect an agent to a bank account yet.
Never type a bank or card login into an AI assistant, even a well-known one. If you want an agent to help with bookkeeping or payments, use only connections your bank or accounting software offers directly, and check what access each tool asks for before you approve it.
