A mid-tier step up from the already-seeded T20/T20-W, same Fireware default-credential model. WatchGuard's own Help Center states: "To connect to Fireware Web UI on Interface 1, browse to https://10.0.1.1:8080. User name: admin Passphrase: readwrite."
Factory reset
Factory-reset via the unit's recessed reset button restores admin/readwrite (and the secondary status/readonly account) at https://10.0.1.1:8080 on Interface 1; see WatchGuard's official Fireware documentation for the full procedure.
