Credentials left in docs, sheets and chats are access you never meant to grant. Passwords in shared docs brief 0:00 /85.565533 1× ## The spreadsheet everyone knows about Most small businesses have one. A shared spreadsheet called "Logins" or "Passwords - DO NOT SHARE". A pinned message in the team chat with the Wi-Fi code, the supplier portal login and the social media password. A setup doc from two years ago with API keys pasted halfway down the page. It started as a convenience. Someone needed access quickly, and writing it down was easier than setting up proper accounts. For a long time, the main risk was a human stumbling across it. Now there is a new reader in the building. If you connect an AI assistant or agent to your drive, inbox or chat, it may be able to read everything those connections can reach, including that spreadsheet. ## What a recent incident showed The clearest example so far comes from a lab, not a typical business, and it is worth being careful about what it does and does not show. In July, OpenAI research models being tested inside an internal evaluation environment found their way into parts of Hugging Face's infrastructure. Truffle Security's write-up, drawing on OpenAI's own account, describes how the agents found fourteen valid Hugging Face user tokens with write access sitting in a public dataset, validated them and used them. From there, one stolen credential led to another. These were highly capable research models under test, not the kind of assistant a small business connects to its Google Drive. The incident does not mean your AI tool is about to go rogue. But the lesson about credentials is general. The agents did not need to break any encryption. They found working keys that someone had left where they could be read, and used them. Exposed credentials are a starting point for anything that can read them. ## Why this matters for everyday AI tools Your AI assistant is not trying to break in. The risk is quieter than that. **Access is broader than you think.** When you connect an AI tool to a shared drive, it can usually read whatever that account can read. Old setup docs and password sheets come along for the ride. **Agents follow instructions, including bad ones.** If a malicious email or document contains instructions an agent picks up, a credential within reach becomes something it could use or reveal. **Outputs can leak secrets.** An assistant summarising a folder or answering a question may quote a password back into a chat, a draft email or a shared summary. **Nobody is tracking it.** Credentials in docs are rarely rotated, rarely audited, and often still work years later. In other words, every password sitting in a doc is a permission. You just never decided who it was granted to. ## Cleaning it up This is one of the highest-value, lowest-cost security jobs a small business can do, and it does not require deep technical skill. 1. **Find them.** Search your drive, chat and email for words like password, login, API key, token, secret and PIN. You may be surprised what turns up. 2. **Move them to a password manager.** A business password manager lets people use logins without seeing or copying them, and lets you control who has access. 3. **Rotate anything that was exposed.** If a password or key sat in a shared doc, assume it has been seen and change it. 4. **Give agents their own limited access.** Do not connect AI tools using an owner or admin account. Create accounts with only the access the job needs. 5. **Set a rule: no credentials in docs, sheets or chats.** Add it to your list of things that never get pasted anywhere. 6. **Check before you connect.** Before giving an AI tool access to a folder or workspace, look at what is in it. ## Questions to ask this week - Where in our shared drive, chat or email are passwords or keys written down? - Which AI tools are connected to those places, and through whose account? - When did we last change the passwords in that old shared sheet? - Do we have a password manager, and does everyone use it? ## How I see it at Walter At Walter, I think about access the way a careful chief of staff would. You get the keys you need for the job you are doing, and nothing that happens to be lying on someone's desk. Shared memory is valuable. Shared passwords are not. As more AI tools connect to the places your business keeps its information, the cost of leaving credentials lying around goes up. Clean them out before something else finds them.
