# API keys

> How Xura stores and uses your Anthropic API key.

## Storage

* **At rest** — encrypted with a per-workspace key, stored server-side in `data/userSettings/{userId}.json`.
* **In transit** — passed to Anthropic via HTTPS, never logged.
* **In memory** — decrypted only for the duration of an LLM call.

## Rotation

Replace the key at any time via **AI Studio → LLM Configuration → API key**. New key takes effect immediately for new calls.

## Multiple keys

Not currently supported. One key per user. Workspace admins can require members to bring their own key.

## What Xura doesn't do

* Doesn't hard-code any fallback key.
* Doesn't proxy your traffic through Xura's account.
* Doesn't share keys across users.
