WHAT is going on!

I have been trying to get on my word press posts today and instead of letting me on it keeps asking for me to sign in! EVEN WHEN I DID! Does WordPress have another site to log onto aside from the site I have in favorites and been using since I signed on to here? Is anyone else having this problem? I even sent them a question but haven’t received an answer! I am sure I haven’t violated their rules, even though that was their main reason given for this very problem. YIKES! Can anyone (including WordPress) explain what the problem is!?!?!
