'OS X Mail keeps asking for iCloud password' Solution

This is soooo annoying to me. I've finally figured out something that works.
Go to Preferences (Mail > Preferences)
Go to Accounts
Select your iCloud account from the left.
Choose the Advanced tab
Change the Authentication setting from "Apple Token" to "Password".
Close Preferences and click "Save" when it asks if you would like to save your changes.
Haven't had it ask for the password since and it was happening ALL THE TIME for me. Hope this helps someone else!
