Managing personal Outlook.com account settings, security, and privacy
I have recently encountered this problem when I upgraded my PC.
Generating And Managing App Passwords is well documented online. The problem is that When requested to enter the App name Yahoo responds with “sorry this feature is unavailable” rather than a drop down list of Apps from which to select.
I had thought of forwarding my Yahoo mail to another mail address but forwarding is ghosted and not available.
Yahoo support were equally unhelpful for 10 minutes until I was cut off. I should at this point mention that I do not subscribe to Yahoo Pro.
Today I did upgrade and was able to forward mail and Generate App passwords.
The subscription was active for less than 30 minutes. The Cancellation location is not easy to locate either but Yahoo do provide this in their welcome to Yahoo Pro email.
