Does this prevent other software running on the same hardware from accessing the keychain?
E.g. on Windows, any program can access the entirety of the credential store for the current user.

One interesting thing I noticed is that Chrome and Firefox can also seamlessly see and use Passkeys I stored in Safari even if normally they don't read the passwords from there.
Using each passkey however still requires a fingerprint every time.
