How can I change the password on my Cisco 877-K9?
Yes, the text in red color is the password.
And as I said, you can configure the user and password like below.
username admin privilege 15 password 7 *********************
This is what you need to use to log into the Router and if you have enable secret configured then it will promot you to type password to go into to the enable mode (Router#) after log into the Router.
And what you find is...
Router(config)#enable secret ...
Once you logged into the router with the user (admin) you will get exe mode (Router>) now if you want go to enable mode (Router>enable) then it will promt you for password (here you need to give the one you create enable secret password)
And the enable secret will encrypt your password instead of plain text.
If you want change username then you need to change the password accordingly.
Hope this clear you...
