# Sign in

> Browser sign-in writes a local credential. CI uses a revocable API key.

## Interactive (`compute setup`)

```bash theme={null}
compute setup
```

The CLI starts a device login, opens (or prints) a URL on [compute.cx](https://compute.cx), and waits for Approve.

On success it writes `~/.compute/config.toml` with mode `0600`. The token is never rendered in the approval page HTML.

```bash theme={null}
compute doctor --json
```

Use this to confirm you are signed in without dumping secrets.

## CI (`COMPUTE_API_KEY`)

1. Sign in on the [dashboard](https://compute.cx/runs).
2. Create a key under [API keys](https://compute.cx/keys). The secret is shown once.
3. Export it in the environment:

```bash theme={null}
export COMPUTE_API_KEY='ck_live_…'
```

The env var wins over `config.toml`. Revoke the key from the dashboard when the job is done.

## Dashboard

The website is for keys, credits, usage, and watching runs. **Create runs from the CLI**, not from the dashboard.

## Next

Add prepaid credit, then [run a function](/get-started/first-run).
