RouterSploit exploits/generic/ssh_auth_keys. Credintials required after successful exploit

I was trying to explore the exploits/generic/ssh_auth_keys exploit in Routersploit Framework. When I run the scan on my router it shows that it is vulnerable. However, when I try to exploit it this is the result I am getting.
OUTPUT OF THE EXPLOIT

After being told that the authentication is successful. I am requested to enter a Username and a Password what I am supposed to enter?
