default boolean supports(final Credential credential) {
        return false;
    }
Determines whether the handler has the capability to authenticate the given credential. In practical terms,
the {@link #authenticate(Credential, Service)} method MUST be capable of processing a given credential if
{@code supports} returns true on the same credential.

@param credential The credential to check.
@return True if the handler supports the Credential, false otherwise.
