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.
