Hello, everyone!
HG8245U general version admin account of the webpage is telecom admin/admin telecom.
If you can not use this default account to login the ONT webpage, maybe because the NMS change it.
1. If you are using the ACS to manage the ONT, check whether the NMS change it.
Node:InternetGatewayDevice.UserInterface.X_HW_WebUserInfo.2.Password
2. If you are using U2000 to manage the ONT, check whether the VAS profile bind this ONT may change it.

Thanks.
