WAPI S RAK5420 Network Trusted Client doesn't work

Hello, I got a WAPI RAK 5420, after installation driver, from official site, I have kind of GUI - “Network Trusted security Client” but on start I need enter some user password, but I have no idea what password I need put there, I didn’t have some documentation with some default passwords, what can I do, to enable it?
And some questions, does it’s really work with Windows 10 properly?
Thank you a lot
