sbcglobal.net login and password issues

Hello - for the last several days, every time I try to access my email, I'm receiving the below error.  I realize that human error. fat-fingering, etc. can cause this to happen sometimes; however, it seems to be something daily.  I know for certain that this is not operator error for the past few times as I've made sure to use the "show" option to confirm I'm not typing it incorrectly. It's a major pain because then I have to log back in on my other laptop and my phone.  AND The last two days, I've selected the "Keep me signed in" option - so why is it asking me to login again, anyway?

I appreciate any suggestions.
