I think it is quite the opposite for the end user. If apps/websites, begin to replace traditional password login with passkeys, this will be a measurable improvement for average consumers.

Passkeys are meant to replace password-based login whereas TOTP apps are only meant as a 2FA method.

That’s completely fair. Appreciate the discourse friend

Admittedly, for some password managers, the passkeys are stored locally and are not accessible in the cloud unencrypted without the decryption keys that exist on devices you authorize.

This may still not make a difference for you though. For me, I consider passkeys, even stored in the cloud, to be enough for the vast majority, so I appreciate these vendors working to make passkeys more easy for the end user.
