Usage of this software requires a compatible YubiKey. Yubico Authenticator is capable of provisioning and using both slot-based credentials (compatible with any YubiKey that supports OTP) and the more powerful standalone OATH functionality found on the NEO, YubiKey 4 and YubiKey 5 series. To use the standalone OATH functionality your YubiKey must have the CCID mode enabled, which can be done by using the YubiKey Manager.
Downloads for all supported operating systems are available on the Yubico Authenticator release page.
The following operating systems are supported. The application may still run on other platforms.
-
Windows 8.1 or later
-
macOS High Sierra 10.13 or later
-
Ubuntu 16.04 LTS or later
On Linux systems, make sure the pcscd service is installed and running.
