Passkeys are a great idea, but everyone involved seems like they want the process to be as much of a pain in the dick as possible. So until the industry pulls it's collective head out of its collective ass (not going to hold my breath on that one), it'll be passwords+2FA for me.
We're trying to implement passkeys at work and the testing has been an absolute nightmare. Literally have no control over the onboarding experience because each tech giant is clamoring over each other, interjecting into the process to be the "home" for your passkeys. It's bananas.
When it's all set up, it's kinda great! But getting set up in the first place is an exercise in frustration.
Edit: my bet is the experience was so ridiculously frustrating, Chrome/Google actually saw some attrition - maybe enough people made Yahoo! Mail accounts that Google noticed
