Step 10: Click on "app passwords"
Step 11: Click Create
Click 12: Give the name to the app password you're creating. With near certainty, the first one you'll want to create will be for Outlook. You'll be creating an app password for *each* non-web based program/device you use. You cannot reuse app passwords. Let's say you've got a tablet, a phone, two different Outlook installations (on two different computers), and a Skype for Business installation. That's five different programs and you'll need five separate app passwords. I recommend naming each app password for the program you'll be using. For example, you might call them Outlook laptop, Outlook desktop, iphone 7, Galaxy S7, iPad, Skype for Business, or something similar.
Step 13: Use the app password the system gives you and track it. Within the next two hours, your devices (Outlook or phone or tablet etc) will prompt you for a password for your email account. Instead of using your regular password, you'll use the app password. You *cannot* reuse app passwords, so you should be sure to 1) make as many passwords as you need and 2) track them until you first use them (the app passwords are useless after you first use them).
