Claude Duet has no credential store: can't securely hold API keys or call APIs
altryne · x · 2026-10-27
Developer altryne discovered that Claude Duet has no credential store — it can't securely hold API keys or act via APIs. In a screenshot, Duet even refuses a user-offered key, explaining that chat input is retained, it doesn't handle credentials, and its shell can't reach the target service, offering Chrome-based link retrieval or manual paste as fallbacks.
A notable capability boundary for anyone trying to automate tasks with Duet.
