=== Features
* Add a credential by scanning a QR code on the screen

Authenticator is capable of provisioning and using both slot-based credentials

To use the standalone OATH functionality your YubiKey must have the CCID mode enabled,
which can be done by using the https://developers.yubico.com/yubikey-manager-qt/[YubiKey Manager].
