OK. So now WordPress has let me back in. Today, I was able to get a verification code in order to sign into the forum. In fact the 'log in' took me to my own WordPress site, but I was able to find my way back. Let me be short without being nasty:
(1) The suggestions you made don't work for me.
(2) Given #1, I went to WordPress helpdesk. I got this response:
I see that you are working with Jackie here:
Please follow her instructions and respond in that thread. I will close this.
Saying 'Cheers' when you're telling a customer to stuff it is snarky at best. Maybe she just didn't read my note that I can't get your suggestions to work.
(3) Of course, I couldn't respond except here. Which required 2-step authentication to be working. Which isn't working. Which is why I want to turn it off. Can you say Catch-22?
4) An authentication code is required to get into this forum. I finally got one today, after two days.
It's very simple. I don't remember the original authentication. I have 10 backup codes. I want to turn this cursed monster off. If I can't under any circumstance turn it off, just let me know that.
