It is with much hesitation that I write this, because I just implemented such a flow.

My reasoning was this: my customers keep forgetting their password and somehow that becomes a trigger to contact me. No passwords, no problem.

I tried convincing them to use password managers but that was pointless.

But I see the pain and frustration so I will add passwords. And I quite liked the passkey idea, have to see how that works. Not that my customers would ever use it, but I would. It literally never occured to me.
