## Backup OTP codes
There is a tricky way to have the same OTP codes on several YubiKeys with
[YubiKey Authenticator](https://www.yubico.com/products/services-software/download/yubico-authenticator/). For instance,
if you've got YubiKey 5C and YubiKey 5 NFC then it's possible to install the authenticator to your PC and phone, insert
YubiKeys to phone and PC and scan a 2FA QR code on both devices. In such situation, you will have the same OTP code on
two YubiKeys what's good in case of a lost/stolen key.
# Configure Smartcard
**Windows** Use the [YubiKey Manager](https://developers.yubico.com/yubikey-manager) application (note, this not the similarly named older YubiKey NEO Manager) to enable CCID functionality.
