# Configure Authenticate Mode

### Setup

By default, we will authenticate users which means users will need to sign on
every connection. This means, that you don'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)

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

<DynamicContextProvider
  settings={{
    initialAuthenticationMode: 'connect-and-sign', // this is the default option
    ...
  }}
>
  {...}
</DynamicContextProvider>
```

### Usage

#### useAuthenticateConnectedUser

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`.

```ts TypeScript
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
      </button>;
    )
  }

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

### Example

This video shows our [demo site](https://demo.dynamic.xyz). 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.
