    Good morning!

    I'm trying to create a short script to change the local admin account password to use a word which will then be followed by the last 7 digits of the computer name but without the 

    example: computer name: WS-STC-3070-003

    password to be changed to : password3070003

    This is what I have managed to put together:

    Import-Module ActiveDirectory

$password = "test" + $ENV:COMPUTERNAME.Substring($ENV:COMPUTERNAME.Length - 8)


Get-LocalUser –Name “admin” | Set-LocalUser –Password $password

    I keep getting the following error:

    Set-LocalUser : Cannot bind parameter 'Password'. Cannot convert the "test3070-003" value of type "System.String" to type "System.Security.SecureString".
At C:\Users\localuser\Desktop\testing admin password.ps1:6 char:55
+ Get-LocalUser –Name “admin” | Set-LocalUser –Password $password
+                                                       ~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (:) [Set-LocalUser], ParameterBindingException
    + FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Microsoft.PowerShell.Commands.SetLocalUserCommand

    Can you give me some tips please.

    Hey,

    That should be pretty easy. You can do:

    $password = "test" + $ENV:COMPUTERNAME.Substring($ENV:COMPUTERNAME.Length - 8)
$password = $password -replace '-'

    and then go and create your secure string (as already discussed):

    $secureString = ConvertTo-SecureString $password -AsPlainText -Force
Get-LocalUser –Name “admin” | Set-LocalUser –Password $secureString

    So if your Computer name is 'WS-STC-3070-003', it will be reduced to the desired lenght first and then the '-' will be removed. You can reverse the oprations of course - First remove the dashes and do a 'Substring' afterwards.

    I hope I could help. Regards,

    Hi,

    you will have to convert the password into something you can pass (Secure String):

    $password = "test" + $ENV:COMPUTERNAME.Substring($ENV:COMPUTERNAME.Length - 8)

$secureString = ConvertTo-SecureString $password -AsPlainText -Force

    and then use the Securte String like that:

    Get-LocalUser –Name “admin” | Set-LocalUser –Password $secureString

    Hope I could help.

    Thank you very much.

    That did work.

    Any idea how to remove the dashes and use only the numbers?
