Hi @tarunsaini120, 

Welcome to TPG Community! 

Here's a community article that can guide you on how to change the WIFI password: https://community.tpg.com.au/t5/Broadband-Internet/Changing-your-WiFi-password-on-your-TPG-Modem/m-p...

Know that your device must at least be connected to the TPG WIFI.
