# API keys

> Create, store, separate, and revoke the keys used by MCP clients.

API keys authenticate MCP calls. Each key begins with `ttm_` and belongs to your Totem account.

## Create a key

Create a key in the dashboard and copy it immediately. Totem shows the plaintext exactly once. After that, Totem stores only a hash and cannot reveal the original value.

## Store it safely

* Put the key only in the supported secret or header configuration for your MCP client.
* Do not put it in your game archive.
* Do not commit it to Git.
* Do not paste it into `CLAUDE.md`, `AGENTS.md`, screenshots, or support messages.

## Use more than one key

You can create separate keys for different MCP clients or devices. Revoking one key does not affect the others.

## If a key leaks

1. Create a replacement key.
2. Update the affected MCP client.
3. Confirm that the five Totem tools appear.
4. Revoke the leaked key.

## If a key is lost

Create a replacement. A lost key cannot be recovered.
