UniFi Dream Machine — login, gateway address and status lights
Open a browser on a device connected to your UniFi Dream Machine and go to 192.168.1.1, or unifi/.
There is no factory password: you created one during setup.
The UniFi Dream Machine is a firewall router from Ubiquiti, in UK use Superseded; no vendor EOL notice. This page covers the four things people actually come looking for: its settings address, how its login works, what its lights mean and how to reset it safely.
What is the UniFi Dream Machine gateway address?
The UniFi Dream Machine settings page is at 192.168.1.1. Type that into the address bar of a browser — not into a search box, which will just search for the number instead of opening the page.
You can also use unifi/, which reaches the same page and is easier to remember.
Your device has to be connected to the UniFi Dream Machine itself for this to work — over its Wi-Fi or by cable. On mobile data, or connected to a different network, the address goes nowhere.
Read this as a fallback rather than a fixed address. Ubiquiti's wording is that the switch ports are "set to DHCP Server with the fallback IP address, 192.168.1.1/24" — so if the console has been given a different LAN subnet, 192.168.1.1 goes nowhere, and 192.168.1.0/24 is a very common collision with an ISP router. The documented local address is unifi/ typed into a browser, and setup.ui.com is the documented setup address, in Chrome specifically. First-time setup also raises a temporary Wi-Fi network called UDM Setup, where the last four characters come from the MAC address on the bottom label. Unlike the Dream Router and UniFi Express, the UDM has no screen, so there is no way to read its address off the device — Ubiquiti's suggested fallback is the WiFiman app's network scanner. Recovery mode, separately, is on 192.168.1.30.
What is the default username and password for the UniFi Dream Machine?
You set it during setup
The UniFi Dream Machine does not ship with a password to look up. You create one yourself the first time you open its settings, and that is the credential you need.
There is no default password for the UniFi Dream Machine and Ubiquiti does not publish one. You create the admin account yourself during the first-run setup wizard, and that is the credential you need — Ubiquiti's own instruction is to "enter the Username and Password that you created in the UniFi Setup Wizard". For a local-only deployment the documented default username is admin, but the password is whatever the installer chose. Most deployments sign in with a UI Account instead, which is a cloud account rather than a device one. Any site quoting a fixed UDM password has invented it.
If you never wrote it down. A reset wipes the UniFi OS configuration the console holds: networks and VLANs, firewall rules, port forwards, VPN configuration, Wi-Fi names and keys, and the adoption records for every device it manages. The part that catches people is what it does not do — it does not release those downstream devices. Ubiquiti states that "the physical reset button does not remove the device from any applications it was adopted to", so after the console is rebuilt the switches and access points still believe they belong to the old one and report "Managed by Other". Each then needs its own factory reset, a restore from a backup that already contained them, or reassignment through the mobile app.
Check the unit too. The bottom label carries the MAC address, whose last four characters name the temporary setup Wi-Fi network. It does not carry a password.
What do the lights on the UniFi Dream Machine mean?
Here is what each light on the UniFi Dream Machine is telling you, and what to do about it.
| Light | What it means | What to do |
|---|---|---|
| Systemsolid blue | Configured, adopted and running normally. | |
| Systemsolid white | The device is ready to be configured, or ready for adoption. | This is the state a new or freshly reset console sits in. Run the setup wizard. |
| Systemflashing white | Booting up, initialising or shutting down. It flashes about twice a second. | Wait for it to settle. |
| Systemheartbeat white | A double-pulse rather than a steady flash — a firmware update is in progress. Ubiquiti notes the UDM flashes white only during an upgrade, where other UniFi devices alternate white and blue. | Do not interrupt it and do not remove power. |
| Systemslowly flashing blue | A client is connected to the UDM over Bluetooth. This pattern is specific to the UDM. | |
| Systemflashing blue | Blue with a brief flash to off every five seconds — there is no internet connection. This pattern is specific to the UDM. | The console is running but has no route out. Check the WAN port, then whatever is upstream of it. |
| Systemrapidly flashing blue | The Locate feature has been activated from UniFi Network. | Somebody is trying to identify this device. It stops on its own. |
| Systemcycling through colours | Cycling off, white and blue at one-second intervals — the device is in recovery or TFTP mode. | You get here by holding Reset before applying power, or by holding it too long during a reset. Power-cycle the unit if you did not intend it. |
| Systemoff | The device is offline. | Check power first. |
How do you reset a UniFi Dream Machine?
What you lose. A reset wipes the UniFi OS configuration the console holds: networks and VLANs, firewall rules, port forwards, VPN configuration, Wi-Fi names and keys, and the adoption records for every device it manages. The part that catches people is what it does not do — it does not release those downstream devices. Ubiquiti states that "the physical reset button does not remove the device from any applications it was adopted to", so after the console is rebuilt the switches and access points still believe they belong to the old one and report "Managed by Other". Each then needs its own factory reset, a restore from a backup that already contained them, or reassignment through the mobile app.
- Ubiquiti gives a model-specific instruction for the UDM: with the device fully booted, "press and hold the Reset button for about 10 seconds until the System LED becomes solidly lit light blue. After a few seconds, the LED will turn off, and the device will automatically reboot." Timing matters in both directions — Ubiquiti notes you can hold it too briefly, which just reboots the unit, or too long, which drops it into TFTP recovery mode instead. The device has to stay powered throughout.
- Hold it for About 10 seconds, until the System light turns solid light blue. Ubiquiti's generic figure across UniFi devices is 5 to 10 seconds depending on the model..
- Release, and give the unit a few minutes to restart before trying to connect.
A reboot is not a reset. A short press reboots the console and keeps every setting. Only the full ten-second hold clears the configuration.
What if you cannot get into the UniFi Dream Machine at all?
It depends entirely on whether a UI Account is attached. If one is, use Forgot Password on the login screen and the reset email goes to that account. If the deployment is local-only, Ubiquiti is blunt about the outcome: those credentials "cannot be recovered unless an SMTP server was manually created", and "if you are already the owner and still cannot access your credentials, there is no way of recovering the current UniFi deployment. You must factory reset all devices and set up UniFi as new. We do not have access to users' credentials." So the cloud account is the recovery route, and a local-only console with no mail server configured has none.
If that does not work, a factory reset will always get you in, at the cost of every setting on the unit.
