1. Recommended Login Method
Do not enter the panel password manually if you have WHMCS billing access — use secure one-time login (SSO).
- Log in at vpnvendor.store.
- Open the client area.
- In the sidebar, find the "Management Panel" block.
- Click "Server Management Panel".
- A new tab opens: panel.vpnvendor.store with automatic login.
2. Conditions for Successful Login
SSO works only if:
- you have at least one VPN server service in WHMCS billing;
- your profile has panel_login and panel_pass filled in (assigned at activation);
- the service is not suspended for non-payment.
Otherwise you will see: "You have no active servers that you can manage…" — pay the invoice or wait for activation.
3. Direct Login (Fallback)
If SSO is unavailable:
- Open panel.vpnvendor.store/login.
- Enter panel email and password from your WHMCS billing profile fields.
Panel credentials are issued by VPN Vendor support; email may match WHMCS billing email, but passwords are for separate systems.
4. Security
- Do not share your panel password with third parties.
- Log out of WHMCS billing on shared computers.
- The SSO token is single-use and short-lived — do not copy the URL from the address bar for reuse.
5. Next Steps
After logging in to the panel, see "Manager Guide: VPN Server Management Panel" in the "VPN Client Management Panel" category.
