accountsd wants to use the "login" keychain

Hi all,

I have logged on to my MacBook Air (2014 on Sierra 10.12.1) and now I get a series of pop up boxes that are asking me to enter a keychain password. I enter a password which I think is correct into one of them and it seems to go away but when I turn on and use the Mac again I have the same issue. I'm a bit concerned as the logo on the popup of some of them suggests it's doing something to be system and I'm wary of the security (lots of passwords in my keychain!)

Does anyone know how to make this go away?

Thanks
