Secure email key
I use Yahoo to access my AT&T email account. My email address is through bellsouth.net (yeah, I've had it that long). Every 2 weeks when I go to log back into the email access page, I receive the error code 203 (I think). Two weeks ago, I went through the steps to reset the password, and set up a secure email key, but still have not been requested to provide the secure email key. I am now again locked out of my email account again, but am still able to access it through my AT&T mobile phone. Is there a trick to being able to access the email?? I've been fighting this battle over and over again for several months now. I use a desktop PC running Windows 10 on it. I use the browser to access the Yahoo site which then redirects me to AT&T Currently site. Is there anything I can do to end this miserable business, or will I have to abandon my old email address for a different one? HELP.
