Mail username and password error

How do you get to that box? Seriously, there is nowhere I can see where to enter a password for those two Gmail accounts.

And my Dreamhost account password is correct.

Mail keeps logging me out of three of my email accounts (two Gmail and one Dreamhost).

When I restart, everything is fine for a short while, but after a while they disconnect.

I've gone into Accounts in Mail preferences, but I don't see anywhere in the Gmail accounts where I can enter a password. For the Dreamhost account, there is a field for password, and it is correct.

Any ideas?
