But the services do not store your biometrics, only a public key while the private key remains on your device.
So, if your device gets stolen you remove that passkey from your account. Similar to what you would do if you loose a FIDO stick like a YubiKey or SoloKey.
Biometrics are only used to access the locally stored private key and you can also use a PIN or password for accessing this.
