Can you help me understand how it replaces the password entirely? What if I lost my phone, or just deleted their app? Does it basically fall back to letting you click a link in your email to approve logging in? Or, SMS, or...? I've been skeptical of it.

Fortunately iCloud Keychain means my current Y! password is random as hell and not reused anywhere, but I'm slightly nervous wondering what the hell password I had in 2014 or 2012 or whenever this stupid leak happened. :/
