I want to create an app password for use with an application that accepts a login and password only. The application is MailtoX Desktop. I'm using it to migrate Microsoft Online mail to Gmail.
The application won't accept my main login because this requires additional authentication. I see this additional security when I set up the account in Thunderbird.
I have searched guides to find the solution but nothing I've found seems clearly directed at the right web app. For example, the name of the service varies across documentation and the page and section titles in Microsoft Online don't quite match. It seems that the guides are out of date or for a similar but different product.
One guide directed me to this link but "Add App Password" isn't listed:
How do I get this to appear?
