Cross-platform application for generating Open Authentication (OATH) time-based TOTP and event-based HOTP one-time password codes, with the help of a YubiKey that protects the shared secrets.

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.
Looking for a command line option? That is available in the YubiKey Manager CLI with the
ykman oath commands.
