In TSD54E, a red warning message "The password is too simple. Please change after login!" will appear if a weak password is detected; entering the temporary password "000000" will redirect you to the password change interface, and the warning will disappear after successful update, while the default password "888888" remains available for urgent access if immediate login is required before password modification.

In TSD54E, enter the default password “888888” to log in to the management system, and the system won’t request you to change password.

> [!NOTE]
> Note: The software will be locked after three consecutive invalid password attempts. To unlock it, reboot the machine.
