# How do I authenticate and verify my connection to Massive Network?

1. Authentication Requirements:
   * PROXY\_USERNAME and PROXY\_PASSWORD (found in [Profile](https://partners.joinmassive.com/profile) section)
   * Choose the appropriate port:
     * 65535 for HTTPS
     * 65534 for HTTP
     * 65533 for SOCKS5
     * 1080 when default ports are blocked by firewall

2. Verification Steps:

```bash theme={null}
curl -x "https://network.joinmassive.com:65535" -U "PROXY_USERNAME:PROXY_PASSWORD" http://ip-api.com
```

Successful connection will return your IP information
Error **407** indicates invalid credentials.
