## roboto auth login

Sign in through your browser and save a new access token to a profile in the Roboto config file. Select the profile with the top-level --profile flag (default: ROBOTO_PROFILE, then the config file's default profile, then 'default'). Replacing an existing profile's token requires --overwrite.

```bash
roboto auth login [-h] [--endpoint ENDPOINT] [--no-browser]
                  [--port PORT] [--expiry-days EXPIRY_DAYS]
                  [--overwrite] [--set-default]
```
