For too long I have ignored the deficiencies in Get-Credential, so now I am going to fix them. Ready?
function Get-Credential($caption,$msg,$domain,$name){$Host.UI.PromptForCredential($caption,$msg,$name,$domain)}
Ok, that’s better than the default, whew! At least you can specify the prompt text and the domain and default user name … but there are so many other options that are missing from that dialog —like remembering my credentials for goodness sakes. I know many places forbid using the “remember” option for credentials, but why is that decision not up to me?
Well, I can’t make all of those options appear (at least, not without compiling a pinvoke function to call the Win32 API) nor can I force PowerShell to use the new Vista/2008 Credential function (which is Common Criteria compliant in Vista) instead of the older CredUIPromptForCredentials ... but I can give you the most requested feature for Get-Credential: a -Console option to force the prompt to happen in the console instead of in a “CredUI” pop up.
Note: I kind-of messed up here, this will break if you’re used to using the -Credential parameter for Get-Credential to provide a default user name. I’ll fix it shortly.
