Password reset problem

Hello All,

Today we got odyssey blue j4125 mini PC. After installing SSD card and Wi-Fi antenna, I powered on the system. The moment it powered on, the system shows password expired and must be changed. Its not allowing us to change to new password also. I’m attaching the screenshot during Sign-in process…

Please advise me on the above issue

Default system without password. You can input space for instead.
