Yahoo Mail (@yahoo.com): Generate 16-Digit App Password (Full Laifaxin Binding Flow)
Just 1 step to bind Yahoo Mail to Laifaxin — generate a 16-digit app password on Yahoo's Account Security page, paste it into Laifaxin. Yahoo requires 2-Step Verification to be enabled before this option appears. The password field must use the app password (NOT login password), otherwise it fails 100% of the time.
