Dashboard authenticated user

Hosting with IIS i can enable windows authentication on IIS which allows me to authenticate to dashboard using AD account

i have authentication enabled for my dashboard which puts a user account in top right of dashboard with option to sign out

but wondering about a few things

is it possible to have the authenticated users id displayed in upper right of dashboard instead of Admin

is it possible to access the authenticated users username and password to use when running certain commands (using pscredentials)

is it possible to use forms authentication when accessing the dashboard similar to when accessing the admin page

when i toast $ClaimsPrincipal the output is security.claimsprincipal
toasting $user outputs admin and toasting $env:username outputs the app pool id

im would like to access the account that authenticates to the dashboard

any feedback much appreciated
