how to grab only username from get-credential

Hi guys, I’m creating a script to map network drives over a VPN connection. To connect to the network drives, I’m pulling credentials through get-credential.

write-host "Please enter your username and password." $mycredentials = get-credential -username domain.local New-PSDrive -Name Z -Root \server.domain.localmisc PSProvider filesystem -Credential $mycredentials -Persist -description "misc" 

This is all well and good. However, one of the drives I need to map is a user home folder, which is normally mapped to server.domain.localusers%username%

Is there any way for me to pull the username portion of the credential (the part that comes after domain.local) to pipe it into the network drive root path? Thanks for your help!
