192.168.1.123 router login
To open the admin panel, type 192.168.1.123 into your browser's address bar. If the page does not load, this is probably not the gateway address on your network — see the checks below.
192.168.1.123 router passwords
Where to find them:
- The label on the underside or back of the router — most manufacturers print the default admin username, password and Wi-Fi key there.
- The quick-start card or manual that came in the box.
- Your ISP's account portal, if the device was supplied by them — many set a unique password per line rather than a shared default.
There is no documented default username and password for 192.168.1.123, so none appears here. Login details attach to a device, not to a private address, and an address this far into the DHCP range often belongs to a phone, television, printer or smart plug with no web interface whatsoever. Where a device does ask for credentials, its factory pair is printed on the label fixed to the casing, listed in the quick-start guide, or documented on the manufacturer's support site under the exact model number.
How to log in to your router
Type 192.168.1.123 into your browser's address bar and press Enter. Type it by hand rather than accepting an autocomplete suggestion, which often fills in a different address you visited before.
If the browser reports that it cannot reach 192.168.1.123, this is not the gateway address on your network. On Windows run ipconfig /all and read the Default Gateway line; on macOS open System Settings, Network, Details, TCP/IP; on Linux run ip route and read the address after "default via".
If the login page loads but rejects your credentials, and you have never changed them, use the defaults printed on the device's label. If they have been changed and nobody knows the new password, a factory reset is the only way back in.
If you do not know the password
If a device at this address has an administrative interface you can no longer open, a factory reset restores the original login at the cost of everything else stored on it: pairings, network settings, schedules, saved accounts and firmware preferences. Because no vendor is known to ship 192.168.1.123 as a default gateway, do not assume any particular reset gesture — check the model's own documentation, since some devices reset from a button, others from a sequence performed in a companion app. Attempt a stored password or a saved backup first; both are less disruptive than starting over.
192.168.1.123 lives in 192.168.0.0/16, private space reserved by RFC 1918 and masked at 255.255.0.0 for a total of 65,536 addresses. This is the block that consumer networking is built on: home routers, mobile hotspots and small office access points nearly all ship with a gateway inside it. The consequence is duplication on an enormous scale — the same address exists simultaneously on innumerable unrelated LANs, and no traffic addressed to it crosses the public internet.
The relevant segment is 192.168.1.0/24, running from 192.168.1.1 to 192.168.1.254 with a broadcast address of 192.168.1.255. Host position 123 lands near the middle of the range, well inside the pool most consumer routers use for automatic DHCP assignment. A device here has almost certainly been given the number by the router rather than configured manually, and unless a reservation was created, that assignment can shift after a lease expires or the router restarts.
Typically people arrive at this page after noticing 192.168.1.123 in a list of attached devices, in a log entry or in the results of a network scan, and want to determine which piece of hardware is behind it. Our records include 254 other addresses across this /24, and this one sees around 138 lookups annually.

Comment: These addresses are in use by many millions of independently operated networks, which might be as small as a single computer connected to a home gateway, and are automatically configured in hundreds of millions of devices. They are only intended for use within a private context and traffic that needs to cross the Internet will need to use a different, unique address.
