# FIDO2 / Webauthn Support

Browser supports the use of FIDO2 or PIV cards with NFC.  To enable this functionality, you will need to specify the specific URLs where you want to enable this feature.  This enables the WebAuthn protocol within the browser, allowing websites to determine that it can use a Security Key during authentication.

In your configuration file, specify the `webauthnPaths` parameter with a comma-delimited list of the hostnames where you expect FIDO2 or PIV cards will be used.   The example below is used to allow the use of FIDO2 security keys for Azure AD:

```
"browser" : {
   ...
   "webauthnPaths" : "login.microsoftonline.com,login.live.com",
   ...
}
```
