# Create client credentials

### Preparation

For a mass deployment of clients, where each client shall use its own `client_id` and `password`, proceed as follows:

1. Generate an API key with scope `clients`-auth.
2. Go to client access and generate a pairing script for any of the clients.
3. Download the bash or PowerShell script to your desktop, but don't execute it.
4. Open the scripts with an editor and go to the line where variables `CLIENT_ID` / `$client_id` and `PASSWORD` / `$password` are defined.
5. Delete the lines and replace with the below snippets. Each time you execute the script, new client credentials are created via an API call.
6. Now copy this script to new clients and execute.

### Generate client credentials on Windows with PowerShell

```powershell
#
# Create new client credentials
#
$apiToken = "xxxxx_b4306692-389c-4f4b-8c3c-50638ef07086" # Use token with 'clients-auth' scope
$apiUrl = "https://rport.example.com:443/api/v1/clients-auth"
$apiUser = "john"

$password = (-join ((48..57) + (97..122) | Get-Random -Count 14 | % {[char]$_}))
$client_id = $env:computername
$body = @{
    id=$client_id
    password=$password
}
$json = $body|ConvertTo-Json
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $apiUser,$apiToken)))
Invoke-RestMethod -Uri $apiUrl -Headers @{Authorization = "Basic $base64AuthInfo"} -Method Post -Body $json -ContentType 'application/json'

```

### Generate client credentials on Linux with bash

```bash
API_TOKEN="xxxxx_8fdef130-6597-4522-ae67-62feabfcf05d"
API_USER="john"
API_URL="https://rport.example.com:443/api/v1/clients-auth"

PASSWORD=$(openssl rand -hex 10)
CLIENT_ID=$(hostname -f)  # or use /etc/machine-id
BODY="{
    \"id\":\"${CLIENT_ID}\",
    \"password\":\"${PASSWORD}\"
}"
curl -fsu ${API_USER}:${API_TOKEN} ${API_URL} -H "Content-Type: application/json" -d "${BODY}"
```
