By default, we will authenticate users which means users will need to sign on every connection. This means, that you donโ€™t need to set any prop to automatically authenticate users.

That being said, you can explicitly control the settings using the initialAuthenticationMode prop and setting the value to connect-and-sign.

initialAuthenticationMode (optional)

import { useDynamicContext } from "@dynamic-labs/sdk-react-core";

    initialAuthenticationMode: 'connect-and-sign', // this is the default option



If you elect to avoid authentication initially by using connect-only, but at some point you want to authenticate your connected users (ie, prove ownership of the wallet), then you can call authenticateUser to trigger a sign request.

You can check the boolean isAuthenticating to check on the status of a user that is authenticating which will be either true or false.

import { useAuthenticateConnectedUser, useDynamicContext } from "@dynamic-labs/sdk-react-core";

const Element = () => {
  const { user } = useDynamicContext();
  const { authenticateUser, isAuthenticating } = useAuthenticateConnectedUser();

  if (!user) {
    return (
      <button onClick={authenticateUser} disabled={isAuthenticating}>
        Authenticate user

  return <div>User is authenticated!</div>;


This video shows our demo site. Here we start with a connected user who has not yet authenticated. We call the authenticateUser method and signature request appears. Once the user signs, then Dynamic verifies the signature and returns a JWT.
