Bank of America warns against sharing bank credentials with AI agents
Bank of America emailed customers urging them not to share banking usernames or passwords with AI assistants or agents, including tools that act on their behalf. A spokesperson confirmed the email was authentic, which warned that customers could be responsible for activity resulting from access they voluntarily granted, subject to applicable consumer protections. Android Authority also reported that some major US banks are restricting external AI agents or using bank-authorized read-only connections.
The warning establishes a boundary for agentic payments: banks are distinguishing between authorized, read-only financial access and giving AI agents credentials that can move money or change account settings.

TL;DR
- Bank of America is warning customers not to share banking usernames or passwords with AI assistants and agents.
- Customers could be held responsible for activity resulting from voluntarily granting an AI agent account access, subject to applicable consumer protections.
- As Gemini, Claude, ChatGPT, and other AI assistants become more autonomous, banks are increasingly concerned about unauthorized access and liability.
AI assistants can write your emails, book appointments, shop on your behalf, and increasingly handle tasks you’d rather not do yourself. It’s the kind of convenience that’s hard to resist, even as questions grow about how much access we’re giving these tools. However, letting an AI assistant manage your calendar is one thing. Trusting it with your life savings is quite another, and Bank of America would rather its customers didn’t find out the hard way.
