PowerShell script to show all wifi passwords saved in Windows

wifi-passwords.ps1

(netsh wlan show profiles) | Select-String "\:(.+)$" | %{$name=$_.Matches.Groups[1].Value.Trim(); ($details=netsh wlan show profile name="$name" key=clear) -and ($pass=($details | Select-String "Key Content\W+\:(.+)$").Matches.Groups[1].Value.Trim() -or "N/A"); [PSCustomObject]@{PROFILE_NAME=$name;PASSWORD=$pass}} | Format-Table -AutoSize

Microsoft changed something in Win11 25H2. This one should do the job ;-)

Create a list with all WIFI Credentials

$outputFile = "$env:TEMP\wifi_list.txt"
netsh wlan export profile key=clear folder="$env:TEMP"

Get-ChildItem "$env:TEMP\WLAN-*.xml" | ForEach-Object {
$xml = [xml](Get-Content $_.FullName)
$ssid = $xml.WLANProfile.Name
$password = $xml.WLANProfile.MSM.Security.sharedKey.keyMaterial

"SSID: $ssid" | Out-File -FilePath $outputFile -Append -Encoding UTF8
"Passwort: $password" | Out-File -FilePath $outputFile -Append -Encoding UTF8
"------------------------" | Out-File -FilePath $outputFile -Append -Encoding UTF8

Remove-Item $_.FullName

}
