WordPress is a good content mangement system for building websites, but it will be better if you build like mobile apps, 
With the wordpress rest api you can create posts, edit posts, view posts, Users, Uploading Media etc… 
but the problem with the wordpress rest api it does not provide any authentication methods for third party application like mobile apps 
The Jwt Plugin on wordpress.org does provide that
and this plugin is just a addon for that plugin
So this plugin is useful if you don’t want to make another request to fetch user data like Id etc.. 
because you have to get the id of the user in ordet to get all data
It really simple plugin 
it writed with 50 lines of code, the size of the plugin is 3Kb
Note: This Is Plugin For 
<a href="https://wordpress.org/plugins/jwt-authentication-for-wp-rest-api/" rel="ugc">JWT Authentication for WP REST API Plugin</a>
so if the jwt authentication plugin is not installed 
this plugin will not add the fields to it endpoints
and the fields will be added only if the token is getted successfully
Example request (before install the plugin): 
{ 
    “token”: “eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJodHRwOlwvXC8xOTIuMTY4LjAuMTgyIiwiaWF0IjoxNjE0MDg3NDQ2LCJuYmYiOjE2MTQwODc0NDYsImV4cCI6MTYxNDY5MjI0NiwiZGF0YSI6eyJ1c2VyIjp7ImlkIjoiMSJ9fX0.KeAUc7PiTne0_PThsSAWo1ruvl2Ocu-fbCn2jG7zkoE”, 
    “user_email”: “example@example.com”, 
    “user_nicename”: “admin”, 
    “user_display_name”: “admin” 
}
Example response (after install the plugin): 
{ 
    “token”: “eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJodHRwOlwvXC8xOTIuMTY4LjAuMTgyIiwiaWF0IjoxNjE0MDg2NjQyLCJuYmYiOjE2MTQwODY2NDIsImV4cCI6MTYxNDY5MTQ0MiwiZGF0YSI6eyJ1c2VyIjp7ImlkIjoiMSJ9fX0.nyDOICdQcZKbWZo2kQRp_eLBkuxjnK_rpxs-HJREyCg”, 
    “user_email”: “example@example.com”, 
    “user_nicename”: “admin”, 
    “user_display_name”: “admin”, 
    “user_id”: 1, 
    “user_login”: “admin”, 
    “user_first_name”: “sfd”, 
    “user_last_name”: “”, 
    “user_roles”: [ 
        “administrator” 
    ], 
    “user_role”: “administrator”, 
    “user_registered”: “2021-02-17 09:21:29”, 
    “user_url”: “http://localhost”, 
    “user_status”: “0”, 
    “user_avatar_url”: “https://secure.gravatar.com/avatar/22feea4605ac5b7163eac439b5241034?s=96&d=mm&r=g”, 
    “user_activation_key”: “” 
}
Of course you can add the code of this plugin to your Theme, 
but this is not recommened because when you change the theme or update it 
the changes will revert back, you can create child theme for that 
but instead you can just install this simple plugin
Don’t forget to setup (JwtAuthenticatonForWordpress)[https://wordpress.org/plugins/jwt-authentication-for-wp-rest-api/]
<a href="https://github.com/ahmedhnewa/user-data-fields-jwt-plugin" rel="nofollow ugc">Github</a>
<h3>Can Add User Data Fields To Validate Token Endpoint ?</h3>
This plugin can also add user data fields to validate token endpoint,
Unfortunately, the jwt extension does not support using the filter for validate_token function, 
So You Will Need To Modify Some Codes Inside Jwt Plugin Codes 
Go To \wp-content\plugins\jwt-authentication-for-wp-rest-api\public\class-jwt-auth-public.php 
And At The End Of Function That Named validate_token 
In Line 302
Edit This Code 
From : 
/** If the output is true return an answer to the request to show it */ 
 return array( 
 ‘code’ => ‘jwt_auth_valid_token’, 
 ‘data’ => array( 
 ‘status’ => 200, 
 ), 
 ); 
To : 
$value = array( 
 ‘code’ => ‘jwt_auth_valid_token’, 
 ‘data’ => array( 
 ‘status’ => 200, 
 ) 
 ); 
 /** If the output is true return an answer to the request to show it */ 
 return apply_filters(‘jwt_auth_validate_token’, $value, $token);
Now you have done, 
the plugin should be able to add new values by adding a filter
Note : 
If you updated the jwt plugin, 
you should again edit the code because it will be removed
