how to use a comment rater bot?

Hello guys, I was just wondering how to import a list of accounts into a thumbs up rater bot? I have my list of usernames and passwords but when I import it only types username into the bot and never uses the password so i cant login, I was wondering if there is a special way of doing this or its really simple and I just don't know , thanks.

you should probably import it like:

username: password
username: password
etc.
