BT modem (not router/hub) default password

[miahw]

There is a default username and password for the BT modem (not router/hub) using the PPPoE protocol. The username is bthomehub@btbroadband.com - I was wondering whether this is secure? I presume this is safe because the router is protected by a separate password. And if the modem were to be hacked, this would require a physical connection to the modem. If it is not safe, is there a way to change the default username/password?

By the way, is it safe to use the default PPPoE username and password on the modem or should this be changed? It is probably safe to use the default credentials because a hack would require a physical connection to the modem.

The username for your PPoE connection is the same as the millions of other BT users. It merely authenticates you are using BT. There is no password required although third party routers need one to be entered.

This is merely for your connection to the network, there is no way for a hacker to access your modem or router with this method of line authentication.

The PPPoE username and password are generic to all BT customers and cannot be changed. Authentication is via the phone number or FTTP connection details.

Since the username and password is known and open, could this not be hacked?

Thanks for the reply. I thought that this is the case because if this can be hacked, then the hacker would need to physically log into the modem with an Ethernet cable which obviously is not possible to do discretely - the hacker would have to come to your house.

You do not access the BT modem using PPPoE, the modem accesses the BT BRAS using PPPoE with the generic credentials.

I have merged your posts onto one thread to avoid confusion and multiple replies.
