Admin.password file during silent installation of Wowza Streaming Engine

Hi,

According to the article - https://www.wowza.com/docs/perform-a-silent-installation-of-wowza-streaming-engine, we need to create server.license and admin.password file manually but when I tried out the silent installation, the two files were created automatically ?
I used Wowza Installer version 4.8.5 (build 20200616153358).
Apart from this, the content of the admin.password file are different than shown in the article.
My admin.password file looks lik the following

Admin password file (format [username][space][password][space][group])

username password group|group

***** ***** admin|advUser

is this the correct format for admin.password file ?
