Restrict writes to WebAuthn verified users

[witwaycorp]

All, wondering if there's any way to implement write restrictions so that only users verified with passkeys/webauthn can write to the database. I'm thinking of using immudb to store user profile data (webauthn public key, id, etc.) and then when authenticating, I would store auth information only after I verify the signature of the webauthn challenge with the pk in the db.
