I just can’t communicate why or how an average user should use passkeys.

I use them, I like them even, they’re a decently easy flow with good trust boundaries.

Yes, passkeys are hard/impossible to phish, but the fallback flows are exactly as easy to phish as passwords today and are basically a requirement if you implement passkeys.

I can’t recommend using passkeys in Chrome’s password manager, for lock in and portability reasons (plus every browser should have an ad blocker). I can’t recommend the OS based ones because frankly nobody should install windows anymore, and macOS is on the precipice of enshittification. That just leaves password managers, which I think are a good idea, but also a single point of failure.
