Apple Configurator 2 asking to export keychain

Hi

I've been trying to set up a Mac to use Apple configurator 2 to set iphones into our ABM. I've used the instructions from our provider to setup the Blueprints. But, when I plug a device in I get a pop up asking:

Apple configurator 2 wants to export key "Apple ID Authentication 2020-07-30 07:34:50 GMT-07:00" from your keychain.

To allow this, enter the "login" keychain password.

I have no idea what this would be? I have tried all of the usual passwords that we use.

Can someone tell me where it is getting this from?

Thanks.

Richard
