Bridge Mode

I am trying to enable bridge mode for my network so I can use my google wifi points (the google support person told me it would work better if I put the network into bridge mode).  I went to the page http://10.0.0.1 but I am not able to login to change my network. I do not remember changing the password and a help article I read said it should just be username: admin and password: password. I don't know why it won't let me log in and if maybe I changed the password, how do I change it again because I do not remember?
