# Setup Fido2 / Webauthn two-factor-authentication
Another well known two-factor-authenticator is Fido2 / Webauthn. We strongly recommend setting up such a 2-Factor Authentication to protect your account. Please generate a recovery code afterward so you always have a possibility to gain access to your account in case you lose your device.
The webauthn's secret are stored on the device and are only available in the security context that you used to create them. So you need another second factor or recovery codes to login to other devices / clients / apps / extension / ... or risk losing access to your account.
You need a device that supports Fido2 / Webauthn and an up to date browser. All modern devices have a TPM / T2 chip and should support WebAuthn. Psono also supports external devices like for example Yubikeys for WebAuthn.
