If you have an AWS account, I highly recommend keeping your address and phone number current in your account. If you ever get locked out, they're going to call you at that number to verify you are who you say you are. I hadn't updated either bits of information since I started using AWS in 2006. 

My address was an apartment building in Berkeley where I lived for six months or so before buying a house. I never would've guessed that was the address. And the phone number was a 206 area code, which is weird because I was pretty sure I never had a phone from Seattle, but there it was. 

Another bit of advice, if you don't understand the various forms of passkeys and 2FA or the terminology, you should get up on it now. Someone should put up a practice server so you can try it out when access to your AWS account isn't on the line.

In any case, all's well that ends well. The AWS people were pretty good once I got one to listen to me. They have all kinds of hoops you have to jump through before you can get through to one of them. This part doesn't make much sense since I pay hundreds of dollars a month for the service, to keep my archives up and running. I've been a customer in good standing for almost 20 years. 

It seems like I should have the equivalent of a platinum card, but it seems I'm just a random schmuck to their algorithm.
