WebJun 11, 2024 · The HOTP and TOTP algorithm only differ in the fact that the latter uses time as a counter. Since both server and client have access to time, there’s no need to create and manually keep track of a counter. The epoch time (when the counter begins, can be specified as a unix timestamp if time zones are going to be a problem). Time step WebThe "Security Key by Yubico" series (the blue keys) have only the U2F/FIDO2 functionality, so you won't be able to use a Security Key NFC for TOTP. For that, you'll need a YubiKey 5 NFC (the black series). That said, U2F and TOTP are separate and independent functions, so you can continue to use U2F for Bitwarden.
