This parameter has been deprecated, and Palette TUI is always enabled regardless of its value. For more information, refer to [Initial Edge Host Configuration](../site-deployment/site-installation/initial-setup.md).                                                                                                           | boolean | `false`     |

 | `stylus.localUI.login.attemptsBeforeExponentialDelayStarts` | Number of consecutive failed Local UI login attempts before the exponential delay begins. After this threshold, each additional failed attempt doubles the wait time before the user can attempt to log in again. This parameter takes effect only when `stylus.localUI.login.disableRateLimiting` is set to `false` and is supported for Edge hosts built with Palette agent version 4.7.16 or later. | Integer | `3`         |
 | `stylus.localUI.login.disableRateLimiting`                  | When set to `false`, Local UI enforces a short delay after several consecutive failed login attempts and temporarily blocks the user's access. This parameter is supported for Edge hosts built with Palette agent version 4.7.16 or later.                                                                                                                                                            | boolean | `false`     |
