Passkeys are only good if they aren't in a online password manager. They are better than TOTP 2FA in terms of security and phishing resistance. I see 2FA as a last resort when someone even gets into my password manager. Storing passkeys completely makes this useless, as I'm sure anyone that can log into my accounts would've done so by getting a hold of my unencrypted password manager database. Unless android provides a real offline way of storing passkeys in the device, I am not interested alot.

I always thought of passkeys as a convenient way to authenticate.
I am password-less on multiple services.
I have an authentication app on my phone that authenticate me when I am away of my computers. I have passkeys on my personal computer and another set of passkeys on my work laptop.
If I have to authenticate from your computer I simply use my auth app, click on "it's a public computer" and I am good to go.
The dude discovered a butter knife and he tries to replace his spoon with it just to realize it doesn't work well for eating a soup.
Do you add separate keys on every device?
If you do, how long does it take you to add a new device?
For example, when you login on Github, go in your settings, authentication & security on the left.
Click "add passkey", enter your Windows Hello PIN, click save.
It will ask you to enter a name, so I go with ComputerName-GitHub
Click ok.
Done with this device.
How long does it take? Well, how fast can you do these steps?
This does not scale. I have 400 logins in my Bitwarden account right now.
Ok
Fuck DHH
Why not just passkeys with a “magic link” fallback though?
This is the same as forgotten password so ytf not
