Google and other services like PayPal make Passkeys default if you generated one.
Now they expect you to always use them to login on all devices.
I had to remove my passkey from one device for these services because i also use a PasswordManager and I do not trust my local chrome installation to just manage my passkey.
I want to have a Password Manager which I need to unlock when I use it. I also want to keep my 2fa and not break it due to passkey usage.
GitHub was also super shitty with it, suddenly a passkey broke my YubiKey login...
