1. During install, tick Apply lockdown and enter the customer Windows username + a password of 8+ characters (the installer creates the account if missing).
2. Restart the PC. It should sign into that account by itself and open RigPass.
3. To verify: open an admin Command Prompt and run reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v AutoAdminLogon — it must show 1. Also reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\PasswordLess\Device" /v DevicePasswordLessBuildVersion should show 0. Check C:\ProgramData\RigPassClient\harden.log and …\system\autologon.log.
4. If Windows still asks for a password: reinstall with Apply lockdown ticked (or re-run harden.ps1 as Administrator from the install folder). Turn off Windows Hello for that account if it overrides auto-logon. The client re-asserts these flags on every start and every minute via the RigPass Policy task.
