Create an app password in Office 365

1. Sign in to Office 365 and go to the My Account page.
   
2. Choose Security Info > Additional security verification. You'll only see this option if your admin has set up multi-factor authentication for your organization. If you don't see this option, contact your Office 365 admin and tell them to turn on multi-factor authentication.
   
   
3. Choose App Passwords. 
   
4. Choose create to get an app password.
5. When prompted, type a name for your app password, and click Next.
6. Choose copy password to clipboard. You won't need to memorize this password.
   
   Tip: If you create another app password, you'll be prompted to name it. For example, you might name it "Outlook."
7. Past this password into the password prompt for Outlook or type it into your phones email client password prompt.
