Bank of America cautions users against sharing login details with AI assistants

Bank of America warns customers not to share their online banking username and password with any AI‑enabled tool or agent. The alert was sent in an email titled “Protecting your finances in the AI World.” The bank tells users to keep credentials to themselves and not give them to another person or an outside service. The message says that sharing log‑ins with an AI assistant could let the software move money without the user’s knowledge, could trigger the bank’s fraud system and lock the account, or could expose the credentials if the AI service has a security flaw. It adds that most bank agreements hold the account holder responsible for any activity that occurs after they share their login. Bank of America did not comment when asked for a statement about the email. The warning comes as banks, payment providers and processors are still figuring out how to let customers use AI tools for tasks such as “agentic payments,” where an automated agent can buy items at the best price or time. The topic was discussed on stage at TechCrunch Disrupt, where industry leaders said they are grappling with unauthorized agents accessing customer funds.

Context

AI assistants are becoming common for personal tasks, but they are not built to securely handle banking credentials. The bank’s reminder reflects a broader industry caution as financial firms test AI features while protecting user data.
