Deja Vous password reject

And, for about the X time to the 15th power, I am getting my password for my secondary email account rejected. It is the same as my primary account.
AT&T/Yahoo's solution seems to be they change the password to a temp one, then I change that to one of my selection. Then we pretend all is well since that works for a while. The Deja Vous comes back for a visit, and this :crap starts all over again.
I n across something a few months ago when this happened about it being something with the AT&T/Yahoo partnership for their ISP service. I lost it somehow and never did come across it again. Of course AT&T has no clue what I am talking about.
Does anyone have a clue as to what is the cause of this chronic crap?guns:banghead

I remember your last issue well, but not all the details.

Can you login to your ISP's website, and e.g. get to your mail via webmail? Meaning, does the password still work online?

 

Yes, I can go to Yahoo and retrieve mail.
That was one of the ideas AT&T tried.

Not too surprisingly, my secondary email account is recognizing the pw I use, again. However, I am confident withing a few weeks, month or two it will do this again.

Thanks,
