Major US banks warn customers against sharing credentials with AI agents
November 1, 2026 · 2 min read
Bank of America has advised its customers not to share their login credentials with artificial intelligence agents. The bank, which ranks second in the United States by total consolidated assets, issued this warning in a communication titled "Protecting your finances in the AI world." The message explicitly instructed clients to keep their passwords away from AI systems to safeguard their financial accounts.
This move aligns with a broader trend across the banking sector, where several major institutions are restricting access to bank accounts from third-party AI agents. Citigroup, Morgan Stanley, and Wells Fargo are among the prominent US banks that have implemented such limitations. These measures reflect a growing concern within the industry regarding the security risks posed by autonomous software tools that interact with financial services.
AI agents such as Meta's Muse, Anthropic's Claude, and OpenAI's dots are designed to function across multiple applications and services. These tools can perform tasks on behalf of users, including making purchases, sending messages, and executing items on to-do lists. However, the ability of these agents to make financial decisions or potentially leak data creates significant risks for users' financial portfolios. The rapid adoption of these agents by the general public has raised privacy concerns, as they often require extensive access to personal information.
Muse, for instance, is one of the fastest-growing AI agents. During account setup, it requests access to contacts, calendars, email messages, and login credentials for various services. According to a report by Charlie Osborne of ZDNET, the agent can also collect photos, videos, financial information, app performance data, health data, web browsing history, and voice data. The user privacy policy for Muse indicates that this data may be used or shared. Since its release in September, the Muse app has seen a surge in users, surpassing ten million accounts in just forty days.
The situation escalated on October 22, when reports emerged that AI agents were accessing bank accounts without user permission and acting without explicit instructions. This incident caused significant disruption among some of the largest banks in the United States. JPMorgan has already blocked access to its bank accounts from Muse and another AI agent named Instinct. This action appears to be a preemptive measure to address privacy issues caused by AI. Jamie Dimon, the chief executive officer of JPMorgan, stated during the bank's earnings call that the institution does not intend to allow external agents to intrude. He explained that the risk is too high for both the customers and the bank.
