Some time ago, I was wondering how many broadband passwords our landlord had, but I was not very interested. I was bored last night and figured out how to find the broadband password in the router. I know the management account and password of the vro, because I bought the vro, which makes it easy for me to find the broadband account. I have tried asterisks viewer and broadband account password viewer before. They don't work for me. So I was bold enough to guess if I could check the source code of the webpage and find out the broadband account password from the source code. After my first test, it was actually successful. This is too much ...... next let's take a look at the steps. The first step is to log on to the vro. Generally, enter 192.168.1.1 or 192.168.0.1 to open the vro page, the default account password is admin (because vrouters are divided into many types, some of the default account passwords are not admin but others, because many of them are not described here) find the network parameter-WAN port settings, and the account and Asterisk password will appear on the right side. The asterisk password is displayed here, which you cannot view, even if you use a tool, you cannot view it. This may have been designed by the producer. The page is refreshed every second. After this page is reached, we press F12 (I use IE9, so press F12 directly, and other browsers test it by themselves) and a box will appear at the bottom of the page, the box contains various source code of the Web page. Here I have found out which bandwidth account and password are saved, so I can click this item to view the account and password. The two items are: <frameset rows = "*" cols = "155,30, * "border =" 0 "frameBorder =" NO "frameSpacing =" 0 "> <frame name =" mainFrame "src ="/userRpm/MainRpm.htm ">
