Managing personal Outlook.com account settings, security, and privacy
Hello ezpar44
Hi, I'm Karl and will be happy to help you today.
Are you referring to a Yahoo account you created on Yahoo servers or an email account where the ISP is using Yahoo for their email service.
Each ISP may have their own instructions on how to generate the <App Password> so if this is the case, you will need to contact your ISP for the applicable instructions.
For example, my ISP (rogers.com) uses Yahoo servers and the steps to generate the <App Password> are
#1 - Log into the email account
#2 - Click on <Account Information>
#3 - click on <Authorized Applications> --> generate the <App Password>
which differs from the general Yahoo instructions when this doesn't involve an ISP
