Therefore, for services that do not provide any alternate account recovery method, the use of U2F should be carefully considered. If a hardware duplicate or alternate hardware key is not kept and the original U2F hardware key is lost, no recovery of the key is possible (because the private key exists only in hardware). In terms of disadvantages, one significant difference and potential drawback to be considered regarding hardware-based U2F solutions is that unlike with TOTP shared secret methods, there is no possibility of "backing up" of recovery codes or shared secrets. Transmission / creation of authentication code is via USB or NFC between hardware key and computer without manual typing steps.Plaintext code is displayed and typed by user manually, visually.Challenge / response is signed (encoding originating domain/website) to prevent interception and reuse. ![]()
