Authentication without username

With Webauthn, it is possible to authenticate a user without username. This behavior implies several constraints:
1.During the registration of the authenticator, a Resident Key must have been asked,
2.The user verification is required,
3.The list of allowed authenticators must be empty
In case of failure, you should continue with the standard authentication process i.e. by asking the username of the user.
The bundle configuration should have a profile with the constraints listed above:
webauthn:
    credential_repository: '…'
    user_repository: '…'
    creation_profiles:
        default:
            rp:
                name: 'My application'
                id: 'example.com'
            authenticator_selection_criteria:
                require_resident_key: true
                user_verification: !php/const Webauthn\AuthenticatorSelectionCriteria::USER_VERIFICATION_REQUIREMENT_REQUIRED
    request_profiles:
        default:
            rp_id: 'example.com'
            user_verification: !php/const Webauthn\AuthenticatorSelectionCriteria::USER_VERIFICATION_REQUIREMENT_REQUIRED
