You never need an account to use a PFX tool. The two that use the internet, the PFX Executor and copying between computers, talk to a small program called the relay. You can run that relay yourself, on your own PC or VPS. It is free, it makes its keys on your machine, and it never contacts PrecisionFX.
The relay places no trades. Your EAs do, under their own settings, and the copy follower does nothing until you switch it on in two places. If a step doesn't look like the picture, that's normal: open the "Not seeing it?" box under it.
Two of the copiers never use a website. Tick what is true for you.

TradingView and the copy EAs need a safe https:// address. A tunnel gives one.

|---|---|
| Quick test | tunnel = quick. The address changes every restart, so use it for testing only. |
| Cloudflare Tunnel (recommended) | In Cloudflare Zero Trust, Networks › Tunnels, create a tunnel and copy its token. Add a public hostname such as relay.yourdomain.com pointing to http://localhost:8787. Then set tunnel = cloudflare, cloudflare_token and public_address. |
| ngrok | Run ngrok http 8787 --url=https://your-name.ngrok-free.app in its own window and set public_address to that address. |

The relay does not recognise this key. The key is not in relay-config.txt, or its line was deleted. Copy it again.
This key is bound to a different account. Each key belongs to one account. To move it, write new in place of the key and paste the new key into the EA.
The relay makes every key with your computer's own random generator and never sends it anywhere.
No account, no check-in, no updates. The only outside connection is the tunnel you switch on.
Unless you change listen. The tunnel reaches it from inside, with no open router port.
Copies and trades keep their stop loss and take profit. They are just not managed until the relay runs again.
Risk warning: The relay passes your own alerts and trades between your own terminals. Trading carries a high risk of loss and is not suitable for everyone. Copying repeats losses as well as profits.
