Does YubiKey support TOTP?
The YubiKey supports OATH-TOTP via the OATH Application – the Yubico Authenticator software is required to pass the current time to the YubiKey, where it is used along with the secret to generate the OATH-TOTP OTPs.
How does YubiKey TOTP work?
TOTP. The code is generated using HMAC(sharedSecret, timestamp) , where timestamp changes every 30 seconds. The shared secret is often provisioned as a QR-code or preprogrammed into a hardware token.
What is YubiKey OATH?
OATH is an organization that specifies two open authentication standards: TOTP and HOTP. To authenticate using TOTP (time-based one-time password) the user enters a 6-8 digit code that changes every 30 seconds.

Why do I have to touch YubiKey?
The YubiKey has an integrated touch-contact that triggers the OTP generation. Generated OTPs are sent as keystrokes by the emulated keyboard, thereby allowing the OTPs to be received by any text input field or command prompt. Each OTP slot can have a different access code set.
How do I create a YubiKey code?
Right-click the new entry that has been added to the Yubico Authenticator application, and then click Generate code. A message appears in the screen asking you to touch the key.

When your spares arrive, make sure to keep them somewhere safe but accessible – like in a wallet, file cabinet, or personal safe. If you choose to stay with one YubiKey, that’s fine, but be careful not to lose or misplace it. If you do, you may be without access to your accounts for a while.
What is a YubiKey and how does it work?
A Yubikey is a small (about 3cm x 1cm x 2mm) passive USB device. When plugged into the USB port of any PC, it presents itself as a standard USB HID keyboard and, when the capacitive ‘button’ on the Yubikey is pressed, the device emits a character string which implements a one-time password (OTP). Ignoring,…
Can I duplicate or back up a YubiKey?
For security, the firmware on the YubiKey does not allow for secrets to be read from the device after they have been written to the device. Therefore you cannot duplicate or back up a YubiKey or Security Key.
Which websites work with YubiKey?
Yubikey normally works on online accounts: Dropbox, Lastpass, Facebook, and Google. However, there’s an app that lets you use Yubikey for Windows Hello.
Does duo support HOTP or TOTP tokens?
Duo also works with third-party one-time password (OTP) hardware tokens, such as YubiKey OTP or any other non-proprietary SHA-1 OATH HOTP-compatible tokens. TOTP tokens are not recommended for use with Duo, as full support for TOTP token drift and TOTP resync is not available. Admins need to manually import third-party OTP token information into Duo.
