PPP password and it's relationship to security issues

Go to solution

Hi,

 

Just wondering if someone can clean a concern up for me.

 

I have just changed my old BT HomeHub3 and decided to go for a TP-Link router. When I was setting it up I had to enter the PPP username and PPP password. The PPP username I found out was 'bthomehub@btbroadband.com' which just seems to be a generic username? The PPP password I entered was the one I use to log into the BT website. Thinking that the password was a bit weak I changed the password on the BT website. I expected to have to change it on the TP Link router but I didn't as I could still connect to the internet.

 

Can someone explain what the PPP password is for, can I change the password - if so how, if the password is weak does it have any security issues?

 

Thanks

The PPP user name and password is just to authenticate your internet connection as a BT customer. This is in fact accomplished by authenticating against your telephone number, hence a generic user name and password for your router.

In fact a password isn't actually required, it is usually the router that insists on one, anything will do as it isn't used.

Thanks for clearing that up.

 

So, if I understand you correctly, there's no point for a complex password as no one else can use it unless they are using my phone line?

Correct, the password isn't actually being used, its just keeping the router happy. BT HH's don't require a password.
