Passwordless login to web vault ("Login with device")

Hey all, just tried this - but isn’t it extremely insecure to use login with device if the app that is approving the login is on the same computer as my browser that I’m logging in with?

So I’ve set up my Windows Bitwarden installed application as the “approving device”. Then I open the Bitwarden website in chrome and log in, and use “login with device”. On the very same device, the Windows app is open and approves the login.

This means that if someone steals my computer, they have access.

Am I missing something?
