With those instructions, it doesn't look too hard. Without godaddy-specific instructions, I would have had a lot of trouble figuring it out. Unlock registration; get authcode; turn off whois privacy protection; accept transfer. Each done in a different screen.
I went to do that, to discover... this old domain, the oldest I have registered, has both an email and a phone number that I no longer have access to, and which GoDaddy wants to do 2-factor using one of them even though I do have my password. (The last 4 of the phone number I recognize as a landline I last had around 17 years ago, before I had a cell phone. I've had this domain for a while, from before I knew better than to use godaddy). They let me pay them renewal every year without me having to log into my account or notice I can't anymore, which I guess is better than stealing my domain becuase of it, but is also why I hadn't noticed for years I could not log into the account.
So I guess first step is figuring out how to get GoDaddy to give me access to the account again... it looks like that may necessarily involve some disruption/outage to my DNS which is in the old account I can't get access to. We'll see.
edit wait a second, they totally send me a renewal notice to email every year. They know my current email! They are insisting on sending a 2-factor code to a different email I no longer have access to. Wtf is that?
