mail login flagged as suspicious ?
First off I've had a yahoo mail address for almost as long as yahoo existed, but I've never been locked out for logging in too much. The new security is horrible- I'll NEVER give you my phone number to get a login code, just so you can ignore my password. To add insult to injury- you still ask me security questions that were disabled by YOU 4 years ago because you couldn't but leak your customer data to hackers, and I get locked out of my account because I cannot answer those questions when you flag the computer I've been using for the last 5 years to login, as suspicious and block it.
What an amatuerish operation you've become, I managed to get in today just long enough to generate an app password so I can dump all my emails to a PC before I close this account. This should make you happy since I don't have to complain about the 15 second lockout to READING my mail because you don't like thet I have an adblocker running when I visit yahoo pages.
Oh, my idea- hire some high school kids to do your security, they surely can do a better job than all your degreed engineers you have on staff.
