I don't see how Passkeys eliminates the need for 2FA. Seems to me, and I may not understand it, but it seems to me that Passkeys are more of a way to eliminate having to constantly re-enter you password, but do not eliminate passwords. For example, if I set up a Passkey, that's bound to a specific machine/browser/phones/whatever. But if I log in from another device, there are no Passkeys, so I just need to use my password. If my lose my machine/browser/phone, I'm in the same boat -- new device, and I need to login. Thus the password. I don't use any syncing system, I'm not on iCloud, or use apps, or anything like that, so there's no mechanic for distribution of passkeys. Plus that wouldn't work if I wanted to log from my friends laptop, or something like that. Am I mistaken in how this works? How does enabling Passkeys eliminate 2FA? My issues with 2FA aren't so much the 2FA part (yea, it's a pain in the neck, "one more step", etc., but, it is what it is). My issue is that if my 2FA is lost, and my recovery codes are lost, I'm toast. There's no other way to recover. No other mechanic, at least for Github.
