# Parameter :: 6. `sub::`
Controls whether the subscription type line appears in output. Used by both `.accounts` (per stored credential) and `.credentials.status` (from live credentials).
- **Default:** `1` (shown)
- **Constraints:** Accepted values: `0`, `1`, `false`, `true`
- **Purpose:** Allows suppression of the subscription type when only token validity or account name matters.
**Examples:**
```text
sub::1 → Sub: max (default)
sub::0 → line omitted
```
