Open the Yubico Authenticator, hold the YubiKey up to the NFC adapter at the request of the app and touch the metal part of the key. Click the add account icon in the top right corner of the app. Enter the secret key manually or scan the QR code to add a new account to the app and sync it with the server.

The Yubico Authenticator App requires a YubiKey 5 Series to generate OTP codes.

Yubikey Authenticator boasts a higher level of security compared to software-based solutions. It can be used across multiple devices and even offers the convenience of passwordless login. However, it does have some drawbacks. Unlike Google Authenticator, Yubikey Authenticator lacks the ability to transfer backups.

OATH-TOTP - the YubiKey 5's OATH application can hold up to 32 OATH-TOTP credentials (AKA authenticator codes). OTP - this application can hold two credentials, can be registered with an unlimited number of services.

YubiKey has 2 slots where you can set one-time passwords and challenge response features. YubiOn Portal uses Slot1 for the Yubico OTP and Slot2 for the challenge response for offline logon.

It is costly to design, mould, manufacture, sell and support a hardware product, even something as small as this. Since you don't want your 2FA company to go out of business there is good value in knowing they have a stable business model that can actually support a company rather than just burning capital.

So, what happens if you lose your YubiKey? In that case, you can still use your Authenticator app (phew!). While you can't create a backup YubiKey, you can always contact Yubico to get a replacement key.
