What's going on with Yahoo mail? [View all]

I can't log into my account on my desktop but my phone works just fine.

I use google to store and auto fill passwords. I haven't changed email address and as I said my cell phone logs right in. My tablet says the account isn't available at this time. I can get to the yahoo home page and enter my email address and the password but it tells me the password isn't right.

Searched for att/yahoo and found articles about old domains not working anymore,ie sbc, swbell, yahoo. Att is now currently.com??
