ADTRAN Default Router Passwords

ADTRAN supplies carrier access equipment and the Total Access and NetVanta lines.

Point a browser at whatever your computer reports as its default gateway. On Windows that is the Default Gateway line from ipconfig; on macOS, Network settings shows it under the active connection. None of the ADTRAN entries here are for a web interface — they are reached over telnet, which means a terminal or a serial console rather than a browser.

None of them ask for a username; the field is left empty. 3 of them shipped with no password at all. Where one is set, adtran comes up most often, on 4 entries.

All of them are reached over a protocol that puts the password on the wire in clear text, so work from a machine on the same wired network rather than across the internet, and change the password once you are in.

This is not hardware you reset with a paperclip. Recovery runs through the console port: interrupt the boot sequence, tell the bootloader to ignore the saved configuration, start up, read or clear the password, then save and reboot. The exact key sequence differs by platform and is in the vendor documentation under password recovery.

You need physical access and a serial cable for this, which is deliberate. Anything reachable only over the network cannot be recovered this way.
