Updating custom columns on login?

[Altonymous]

I've added some custom columns to my user table.  They are not required fields, however, during login I would like the user to be able to pass me data to put into these fields.  I know how to do it during registration of a user but not during authentication.  Any idea/suggestions on how to go about this?

you need to extend the sessions controller and change the new action with for handling the extra data
