Getting an Issue while generating a token at login time

Hi, actually I am trying to generate token at my login time using an wp_login hook but i am unable to do so, can you provide me any way to do it.

Tell me whether there is any buildin function is there that I can use.

add_action(‘wp_login’, function ($user_login, $user) {
if (!user_can($user, ‘dokandar’)) {
return;
}

$response = wp_remote_post(site_url('/wp-json/jwt-auth/v1/token'), [
    'body' => [
        'username' => $user_login,
        'password' => 'YOUR_DEFAULT_PASSWORD_IF_AVAILABLE', // Not ideal, see note below
    ],
]);

if (is_wp_error($response)) {
    error_log('Token request failed: ' . $response->get_error_message());
    return;
}

$body = json_decode(wp_remote_retrieve_body($response), true);

if (!empty($body['token'])) {
    update_user_meta($user->ID, 'vendor_jwt_token_key', $body['token']);
} else {
    error_log('JWT token missing: ' . json_encode($body));
}

}, 10, 2); I am using this thing but thing is password can’t be accessed directly in wordpress.
