# Installation & auth

```bash
npm install -g @aeontel/cli
```

Authenticate via the browser-based device code flow — Aeontel never asks for
passwords in the terminal:

```bash
aeontel login
```

The CLI opens a browser window confirming an 8-character code, which you
approve on `id.aeontel.com/sign-in`. Tokens are stored at
`~/.aeontel/config.json`.
