The ZTE F6640 is widely deployed by telecom providers. The standard user (user) password is printed on the device label, but the admin account is hidden and uses a predictable or ISP-specific password. This write-up documents a method to obtain or derive the admin password.

If your goal in finding the ZTE F6640 admin password is simply to open ports for gaming, set up a home server, or use your own high-end router (like an ASUS or TP-Link Omada system), you don't necessarily need the admin password.

You only need the user-level password (often printed on the sticker) to access the settings.

This turns the ZTE F6640 into a simple "light converter," passing the raw internet signal to your own router. Your own router then handles all the complex admin tasks (Port Forwarding, VPN, Firewall), and you have full control over that router without fighting the ISP’s locks.

Call your ISP’s technical support. Ask them specifically for the "Modem Admin Password" or "GUI Access Password."

You can delete the TR069_R_VID (Internet VLAN) and set your WAN interface to "Bridge." This allows your personal Asus or TP-Link router to handle the PPPoE authentication, removing double NAT.
