Yubico Authenticator is a tool equipped with numerous features that allow individuals to create and store a unique hardware-backed security key. With this solution, users are able to log into various devices by using only one key.
Its interface is user-friendly and has a straightforward navigation menu. The dark grey theme along with the green font color provides a nice contrast. The menu, however, has very few configuration options.
As for its functionalities, Yubico Authenticator comes with a Touch Authentication feature that stores the credentials on the YubiKey. You can use the QR codes available from the services you wish to protect and generate new codes with only a touch of the YubiKey.
Moreover, the key has a two-factor authentication secretly stored on the YubiKey and not on your desktop. It's a versatile tool because it provides support for multiple personal accounts and for time-based and counter-based code generation.
To sum it up, Yubico Authenticator introduces a new way to secure your personal data and connect to multiple devices by using only one key. I noticed that it does happen to freeze sometimes and continually asks for the key though it's already inserted.
