Yubico Authenticator
Yubico Authenticator is a macOS app for managing and generating two-factor authentication codes stored on a YubiKey.
What is Yubico Authenticator?
Yubico Authenticator is a security and authentication app that helps you manage OATH one-time password accounts with a YubiKey on macOS. It is designed for people who use a YubiKey for stronger sign-in protection at work or for personal accounts. Instead of keeping shared secrets only on the computer or phone, the app works with credentials stored on the hardware key, so you can access your codes across supported devices when the same YubiKey is present. Common uses include setting up time-based or counter-based verification codes, organizing multiple accounts, and using NFC or USB with compatible hardware. The app is also used to manage some YubiKey-related settings and supports desktop workflows for users who want hardware-backed two-factor authentication from a native Mac app.

Safety overview
Status: Safe
This is legitimate security software from Yubico for working with YubiKey authentication data. It may access connected security keys, camera input during account setup on some platforms, and local app storage for settings or logs; that is normal for its purpose. Removing it does not erase accounts stored on the YubiKey itself, but you would lose the convenience of managing and viewing those codes on this Mac until you reinstall it.
Recommendation: Keep Yubico Authenticator if you use a YubiKey for two-factor authentication or account setup on your Mac. Remove it only if you no longer use YubiKey-based codes on this computer; your credentials remain on the hardware key, but local app settings and logs on this Mac may be lost.
