Hey folks! I think I found a pretty easy ipython-side solution to this problem:

The SSH public key I provided on the ticket is newly created and has not been used for WMCS or anything else. What else is needed to do the off band validation?

@SLyngshede-WMF it worked! I can login to wikitech now.

Hi @SLyngshede-WMF , I've tried logging in with the "arinaigum" (not "arinaugum" as you have in your comment, I assumed that was a typo) again this morning, and I am still getting the same error.

Hi! I created the account Arinaigu for Meta Wikimedia and MediaWiki. Then I created a separate developer/Wikitech account arinaigum. I think I read somewhere in the documentation that those accounts' usernames should be different, though I could have misinterpreted something in my first week here. The way I created them, those two accounts are separate, and the developer/Wikitech account is spelled correctly on the ticket: arinaigum.

For more context, if I go to the IDM login page and click on the "Wikimedia Developer Single Sign On" button, I get this:

An update on my attempts to figure out my developer/wikitech account creation issue:

There seems to be a problem with my developer account as well. I created my developer account through the IDM signup page last week, but I haven't received a confirmation email or any other notification that my developer account has been created. So, I am not sure whether my developer account has been created.
Here's what happens when I try to use my developer/wikitech account:

• if I follow a link to a WikiTech page like this one, I can see the content on it, and in the top right corner I see a login button, which suggests that I am not logged in.
• when I click on that login button and try to login on this page with my developer account credentials, I get an error message saying that my password or username is incorrect.
• when I click the link at the top of that page to reset my password via idm.wikimedia.org, I get to this page and see this:
  
• There's no option to log out.
