To send applications to Apple for notarization, 

	xcrun atool ...
	
needs to be called. But atool uses two-factor verification, which is clumsy for shell command. Thus Apple provides a way to assign a password to atool, to replace two-factor verification.

This password seems to expire randomly, usually just at the moment that the pretest period begins. This short document explains how to get a new password.

Recall that my developer account is koch@uoregon.edu. 

Access the Apple ID Account Page:

	https://appleid.apple.com/#!&page=signin
	
This page may offer to sign into koch@math.uoregon.edu. Change this to koch@uoregon.edu. Enter a verification code from iPhone or regular phone. 

In the SECURITY section, click "Generate Password." Enter 

	atool
	
Copy the resulting password and enter into various shell scripts.
