FIDO2 integration prerequisites

To get started, you need the following information available:

  • Instance ID
  • Access Key

For more information on the instance ID and the Access Key, see the API documentation.

Relying party

Before you can integrate WebAuthn, provide the following information about your web application, the relying party:

Relying party name: The name of your choosing, for example: Siven Chocolate Factory.

Relying party ID: The domain or part of the domains of your web applications that you plan to register and authenticate users on, for example:

Origins: The list of the origins of your web application. Each origin has to be explicitly allowed, for example:


As WebAuthn can only be used from a secure context, the origins must be one of the following:

  • A local address: http://localhost.
  • An https:// address on condition that the application provides a valid SSL certificate.

The Relying party ID must be a subset of all the origins you intend to use.

For example, the Relying party ID matches the origin, but not the https// origin.

Autofill UI prerequisites

To enable the autofill UI feature, add the username and webauthn value to any existing autocomplete annotations on the username input field as follows:

<label for="username">Username:</label>
<input name="username" id="loginform.username"
autocomplete="username webauthn">
