Remove need for pin, when set up with fingerprint #20

It seems that I need to set up a pin, before I can add my fingerprint.

This is a problem either:

  1. I choose a weak PIN, and then this is a security issue
  2. I choose a strong PIN, and then I have to remember yet another thing.

Pin can never be removed. Fingerprints can be revoked by the system and
would result in an inaccessible database.

Ah, for users who want fingerprint, but not PIN, rather than asking to set up a PIN, could the user be prompted for their kdbx passphrase, and use that as a fallback instead?

I don't really want to add such a use case flow, in this case, you can
create a really long pin and forget it. Setup keepshare again if the key
gets revoked or the fingerprint doesn't read for some reason
