How to configure your account with Yubikey
Setup YubiKey
To setup Yubikey as multi-factor authentication method, navigate to the multi-factor authentication user settings page: Avatar > Manage account > Multi Factor Authentication. Select the provider "Yubikey" to continue.
The next step will require you to plug your Yubikey and touch it to release a Yubico OTP. Then click on "Validate" to ensure it functions correctly and complete the setup.

Authenticate with YubiKey
After setting up Yubikey, each time you sign-in to Passbolt, you'll be prompted to plug your device and touch it to release a Yubico OTP. Additionally, if permitted by the "Multi-factor Authentication Policy", passbolt can remember your MFA authentication for a month.
