Easy OTP codes on the browser with a Yubikey
What is Yubikey Companion?
Yubikey Companion is a Firefox add-on that enables users to easily insert OTP codes on any website using a Yubikey. It requires the installation of the official ykman tool, a Yubikey, and the Yubikey Bridge native companion app.
This addon allows to insert OTP codes on any web with one click (right click - Generate OTP on a text input). Each website needs to be configured previously to use the codes from a Yubikey. More information on how to install/configure here: https://github.com/dyeray/yubikey-companion.
Note that this addon requires several dependencies to work:
- You need to have a Yubikey.
- The official ykman tool for your Yubikey needs to be installed: https://developers.yubico.com/yubikey-manager/
- You need to install the native "Yubikey Bridge" for this addon (a small native companion app to talk with the Yubikey).
