# Web Authentication

Your users can use hardware keys or their device's biometric readers \(FIDO2\) to authenticate to an instance.

## Hardware keys

</td><td>

Hardware keys are physical hardware that you can use to authenticate. Hardware keys are inserted into a port on your device to provide authentication. For details on registering hardware keys, see [Register a hardware security key](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-security/authentication/mfa-setup-hardware-key-auth.md).

</td></tr></tbody>
</table>## Biometrics

<table id="table_q4j_kyp_dpb"><tbody><tr><td>

\[Omitted image "biometric-2.png"\] Alt text: Biometrics icon

</td><td>

Biometric authenticators use fingerprint or facial recognition to identify users. Your users can use these authenticators on their devices as part of the multi-factor login process. For details on registering biometric authenticators, see [Register a biometric authenticator](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/platform-security/authentication/mfa-setup-bio-auth.md).
