The quickest way to find your T-Mobile WiFi password is to look at the physical device itself. For a T-Mobile Home Internet gateway, the default network name (SSID) and password are printed on the gateway label; for a T-Mobile hotspot, you typically find them under the back cover after removing the battery.
How to find your T-Mobile WiFi password on the device label
If you have never changed your WiFi password, this is the fastest method. For a T-Mobile Home Internet gateway, simply look at the sticker on the bottom or back of the device. The default SSID and password are clearly listed there. For a T-Mobile hotspot, remove the back cover and battery; the default network name and password are printed on the label inside the battery compartment. This gives you immediate access without needing any app or login.
How to find your T-Mobile WiFi password with the T-Life app
If you have T-Mobile Home Internet and your gateway is online, the T-Life app lets you view your current WiFi password. Sign in with your T-Mobile ID, then select "Home Internet" from the Home screen. Go to the "My Wi-Fi" screen, and under "My networks," select your network name. The current password is displayed in the "Wi-Fi network password (key)" field. Note that the gateway must be connected to the T-Mobile Network and able to receive data for the app to work.
How to find your T-Mobile WiFi password via the web interface
For both hotspots and gateways, you can access the admin panel through a web browser. Connect to the device's WiFi network, then enter one of these addresses in your browser:
http://192.168.1.1(for some routers and the LTE Wi-Fi Gateway TM-RTL0102)http://192.168.12.1(for some routers and the Nokia 5G21 Gateway)http://192.168.0.1(for T-Mobile hotspots)http://mobile.hotspot(for T-Mobile 5G hotspots)
The default admin password for the T-Mobile Hotspot web interface is 'Admin' followed by the last 4 digits of the device's IMEI, which is printed on the device label underneath the battery. For the Nokia 5G21 Gateway, the default username and password are on the underside of the gateway. Upon first login to a hotspot's web interface, you will be required to change the default admin password. Once logged in, look for the WiFi settings; an eye symbol or similar icon next to the password field can be selected to reveal the current WiFi password.
What to do if you forgot your customized T-Mobile WiFi password
If you changed the WiFi password and cannot remember it, the last-resort option is a factory reset. On a T-Mobile router or gateway, press and hold the small reset button (usually on the back or bottom) for about 10 seconds. This restores the device to factory settings, including resetting the WiFi password to the original default printed on the label. For a Nokia 5G21 Gateway, you can also use the Reset port or the T-Life app to reset the password to default. After resetting, you can follow the steps in the T-Life app or web interface to set a new password, this is also how you would normally change T-Mobile Wi-Fi password for ongoing security. When changing a T-Mobile Hotspot Wi-Fi password via the web interface, the new password must be at least 8 characters long. The T-Life app is the recommended tool for managing wireless passwords on T-Mobile Home Internet.
