Default router admin credentials are publicly documented for every model. Here’s how to change yours in under 5 minutes.
Routers ship from the factory with a default admin username and password — often 'admin/admin,' 'admin/password,' or a short string printed on the router's label. These defaults are publicly documented for every router model and are the first thing anyone attempts when trying to access a router without authorization. Leaving the default unchanged means anyone on your network (or within WiFi range) can access your router's full admin interface.
A factory reset — whether done intentionally during troubleshooting or accidentally — restores all settings to default, including the admin password. If someone reset the router to fix a problem and didn't re-set the admin password afterward, the router is back to its default credentials. This is particularly common when purchasing a second-hand router that was reset before being sold.
Open a browser on a device connected to your home network and type 192.168.1.1 in the address bar. If that doesn't work, try 192.168.0.1 or 10.0.0.1. Some routers use a custom address — check the label on the bottom or back of the router, which usually lists the admin URL, default username, and default password. You can also find the gateway address on Windows: open Command Prompt and run `ipconfig` — the 'Default Gateway' address is your router's admin IP.
Enter the current admin username and password. If you've never changed them, use the defaults printed on the router's label. Common defaults include admin/admin, admin/password, or admin/(blank). If the defaults don't work and you don't have a record of changing them, you'll need to factory reset the router to restore the defaults — check your router model's manual for the reset button location and process.
Once logged in, look for a menu item called 'Administration,' 'System,' 'Management,' or 'Advanced' — the exact name varies by router model and firmware. Look for 'Change Password,' 'Admin Password,' or 'Router Password.' Enter a strong new password: at least 12 characters, not a word from the dictionary, not the same as your WiFi password. You'll need to log in again with the new password immediately after saving.
While you're in the router admin interface, navigate to the WiFi or Wireless settings section. Check your WiFi password (also called the Network Key or WPA2 Pre-Shared Key). If it's still a default value — typically a short random string printed on the router's label — replace it with a strong passphrase of at least 12 characters. Any device currently using your WiFi will need to re-enter the new password.
In the WiFi settings, check the Security Mode or Encryption setting. It should show WPA3 (preferred on newer routers) or WPA2-AES at minimum. If you see WEP, WPA (without a version number), or 'Open,' your network is using weak or no encryption — change it to WPA2 or WPA3 immediately. WEP can be cracked in minutes with freely available tools.
Record both the new router admin password and the WiFi password in a secure location — either a password manager (Bitwarden, 1Password, or the built-in keychain on iOS/macOS/Windows) or a physical note stored somewhere only household members can access. Losing both the admin password and access to the router label (if you've obscured it) results in needing a factory reset, which disconnects all devices and requires full reconfiguration.
