How do I turn off two-step verification? The posted instructions don't work and it's just another layer of inconvenience, not security.

Those instructions don't work for me.  I get two boxes, one says Status:On with no buttons or live text to click.  The other one says "Current Selections:" and the only choice is "Reset" and it shows my phone number as being the SMS number configured for two-step verification.  There is no button to turn it off as shown in the link above.  This is causing me trouble because my phone app does not handle two-step verification so after a few attempts by my phone to sync, my account gets locked out!  This needs to be fixed.  I chatted with someone about it last night, then I called after the person I chatted with only reset my two-step instead of turning it off.  The person I talked to told me she was going to escalate this issue for me but so far today, I have not seen or heard anything about it.  I would attach an image of the screen but your insert menu doesn't allow for that apparently. When I try to insert an image, there is no link to the file system allowing me to select the file.  I wonder if this function was programmed by the same person who did your two-step verification...

Do you log into Cox with your Primary account or a secondary?  What happens if you Reset?

I log in with my primary account when I need to do admin stuff but my phone would log in several times a day to sync my email on that account.  That's what gets my account locked.  I stopped syncing my primary mail account on my phone app to stop it from locking out my account. 
  When I click reset, all it does is make me choose between using a voice line for the code or get an SMS code.  

It's a stab in the dark, but I've read some recent scripting problems with Microsoft Edge.  Are you using it?  Perhaps another browser.

I do use Edge but I also tried using Mozilla and Chrome and they all have the same result.  I went back to the two-step choices page again and I didn't notice till this time that the message is saying that two-step verification is required!  It wasn't stated on the page where I decided to use it as it was presented as something I could do to enhance my security.  Now, after I agreed to it, I can't use my mail app on my phone for that account anymore.  I guess it's not the end of the world as I can still use Outlook on my PC as it somehow manages to process it.  It's not a very good policy to use a bait and switch scheme to get people to agree get another email address that didn't require it.  I will put in a request to my mail app support to see if they can make a change to accommodate this situation.

Well, thanks for your persistence in trying to help me out.  Maybe it's the OAuth2 thing, but after I read what you wrote, I decided to try enabling sync on my phone app and it is working so far.  I'm fine with requiring 2FA for administering my account as long as it doesn't hamper me from checking the mail on my phone.  Anyway, thanks again

Did you enable OAuth2 in Aqua Mail?

2FA is fine for a website.  Log in with username & password...get a code...enter code...and you're in.  However, email clients can't do this on a chronological basis, such as every 5 minutes.  Therefore, OAuth allows third-party clients (Outlook, T-bird, Aqua Mail) to use a code for the server to allow an Access Token instead of a username & password.

If there is a way to enable it, I haven't seen it yet.  Maybe it's enabled by default.  I tried removing my account and then putting it back to see if it would ask me about it, but there was no mention of it in the software that I noticed.

Wasn't how to enable in the link I sent?
