Fingerprint Phrase, biometrics on Launch?

I have a few questions.

Do the mobile app & desktop browser app share all settings. These are representative of settings in my Firefox/Chrome app that only apply to my Bitwarden phone app.

How is the fingerprint phrase implemented? Apparently, the phrase is chosen for me?

Unlock with biometrics is unchecked on my desktop browser, but my mobile app is already configured for biometric login?

As you can see, I’m a little confused.
