Any Ideas ?

I am looking to point to the last login time on the user object as part of a solution I am building. However neither the process builder nor formulas allow us to point to the standard out of the box user field called Last login time. I found a trigger on another thread that I could leverage

this is the trigger 
trigger lastLoginDate on User(before update){
User u = [SELECT LastLoginDate FROM User WHERE Id =:UserInfo.getUserId()];
for(User c : Trigger.new){        
    c.last_login__c= u.LastLoginDate;
    }
}

It works but I must hit the edit save button on the user record in order for the trigger to fire. What I need is for the trigger to fire when a user actaully logs in . I had assumed that a user logging in would fire the trigger by updating the standard last login field and therefore update my new custom last login field

Any ideas ?

I thought I could build a process to hit a refresh check box every day on all users, this may work as I only need the login day for the solution.

OR

Is there anyone who knows if I could treak the above trigger to fire when someone actaully logs in ?
