Password
— on the device label —

The password is unique to your unit and printed on a sticker on the router (often labelled Password or Access Key).

AC2100 dual-band hardware. Tenda ships no universal credential for the AC21 — the label on the back carries a Wireless Password unique to that unit, and that is what gets you through the very first login at tendawifi.com. The setup wizard then splits them: one password for the wireless, another for management.

Factory reset

Reset: with the router powered on, hold the RESET pinhole down for roughly 5-8 seconds with a pin until the LEDs blink, release, then allow about a minute to reboot. Reconnect to the default Tenda_XXXXXX SSID using the rear-label password, open tendawifi.com or 192.168.0.1, and run the wizard to choose a fresh management password.
