Login User

This plugin is customizable and offers you multiple methods to log in to you website, based on multiple scenarios.

In order to login, users have to send JWT. The plugin, validates the JWT, and if everything is OK, it can extract the WordPress email address or user ID.
Users can specify the exact key of the JWT payload where this information can be found.

Here are the methods how you can send the JWT in order to auto-login:

1. URL
2. Header
3. Cookie
4. Session

If the JWT is present in multiple places ( like URL and Header), the JWT will be overwritten.

This plugin supports multiple JWT Decryption algorithms, like: HS256, HS512, HS384, RS256,RS384 and RS512.

After the user is logged in you can automatically redirect the user to a page like:

• Dashboard
• Homepage
• or any other custom Page ( this is mainly used for redirecting users to a landing page)

You can attach to your redirect a URL parameter redirectUrl that will be used for redirect instead of the defined ones.
In order to use this, you have to enable it by checking the option Allow redirect to a specific URL.

Also, redirect after login offers some variables that you can use in the customURL and redirectUrl.
Here are the variables which you can use in your URL:
– {{site_url}} : Site URL
– {{user_id}} : Logged in user ID
– {{user_email}} : Logged in user email
– {{user_login}} : Logged in username
– {{user_first_name}} : User first name
– {{user_last_name}} : User last name
– {{user_nicename}} : User nice name

You can generate dynamic URLs with these variables, and, before the redirect, the specific value will be replaced.

Here is an example:

http://yourdomain.com?param1={{user_id}}&param2={{user_login}} 

Also, this plugin allows you to limit the auto-login based on the client IP address.
If you are concerned about security, you can limit the auto-login only from some IP addresses.

Register Users

This plugin also allows you to create WordPress users.

This option is disabled by default, but you can enable it at any time.

In order to create users, you just have to make a POST request to the route URL, and send an email and a password as parameter and the new user will be created.

You can select the type for the new users: editor, author, contributor, subscriber, etc.

Also, you can limit the user creating only for specific IP addresses, or specific email domains.

Another cool option is “Generate a random password when a new user is created”.
If this option is selected, the password is no more required when a new user is created a random password will be generated.

Another option that you have for register user is “Initialize force login after register”.
When the user registration is completed, the user will continue on the flow configured on login config.

If auto-login is disabled, this feature will not work and the register user will go on a normal flow and return a json response.

If you want to add custom user_meta on user creation, just add the parameter user_meta with a json. This will create user_meta for the new user.

{
“meta_key”:”meta_value”,
“meta_key2″:”meta_value”
}

These properties can be passed in the request when the new user is created.

• email : (required) (string) The user email address.
• password : (required) (string) The plain-text user password.
• user_login : (string) The user’s login username.
• user_nicename : (string) The URL-friendly username.
• user_url : (string) The user URL.
• display_name : (string) The user’s display name. Default is the user’s username.
• nickname : (string) The user’s nickname. Default is the user’s username.
• first_name : (string) The user’s first name. For new users, will be used to build the first part of the user’s display name if $display_name is not specified.
• last_name : (string) The user’s last name. For new users, will be used to build the second part of the user’s display name if $display_name is not specified.
• description : (string) The user’s biographical description.
• rich_editing : (string) Whether to enable the rich-editor for the user. Accepts ‘true’ or ‘false’ as a string literal, not boolean. Default ‘true’.
• syntax_highlighting : (string) Whether to enable the rich code editor for the user. Accepts ‘true’ or ‘false’ as a string literal, not boolean. Default ‘true’.
• comment_shortcuts : (string) Whether to enable comment moderation keyboard shortcuts for the user. Accepts ‘true’ or ‘false’ as a string literal, not boolean. Default ‘false’.
• admin_color : (string) Admin color scheme for the user. Default ‘fresh’.

Delete User

Delete user it is disabled by default.

In order to delete a user, you have to configure where to search the details in the JWT.
You can delete users by WordPress User ID or by Email address.

Also, you have to choose the JWT parameter key where email or user ID it is stored in the JWT.

Also, you can limit the deletion of users to specific IP addresses for security reasons.

Reset Password

Reset password and change password endpoints are disabled by default.

This plugin allows you to send the reset password endpoint, just by calling an endpoint. An email with the code will be sent to a specific email address.

Also, you are able to customize this email, or even not send at email at all.

The change password endpoint, changes the user password, based on the reset password code.

Authentication

This plugin allows users to generate JWT tokens based from WordPress user email and password.

In order to Get a new JWT, just make a POST request to /auth route with your WordPress email and password ( or password_hash) and the response will look something like this:

 { "success": true, "data": { "jwt": "NEW_GENERATED_JWT_HERE" } } 

If you want to add extra parameters in the JWT payload, just send the parameter payload on /auth endpoint, and add a json with the values you want to be added in the payload.

At some point, the JWT will expire.
So, if you want to renew it without having to ask again for user and password, you will have to make a POST request to the auth/refresh route.

This will generate a response with a new JWT, similar to the one that /auth generates.

If you want to get some details about a JWT, and validate that JWT, you can call /auth/validate. If you have a valid JWT, details about the available WordPress user will be returned, and some JWT details.

If you want to revoke a JWT, access /auth/revoke and send the jwt as a parameter.

The plugin auto-generates the example URL you might need to test these scenarios.

Auth codes

Auth codes are optional, but you can enable them for Auto-login, Register User and Delete user.

This feature allows you to add a layer of protection to your API routes.

The Auth codes contains 3 parts:
1. Authentication Key: This is the actual code that you have to add in the request.
2. WordPress new User Role: can be used when you want to create multiple user types with the create user endpoint. If you leave it blank, the value configured in the ‘Register Settings’ will be used.
3. Expiration Date: This allows you to set an expiration date for you auth codes. The format is `Y-M-D H:m:s’. Example : 2020-12-24 23:00:00. If you leave it blank, it will never expire.

Expiration date format: year-month-day hours:minutes:seconds

CORS

The CORS standard it is needed because it allows servers to specify who can access its assets and how the assets can be accessed.
Cross-origin requests are made using the standard HTTP request methods like GET, POST, PUT, DELETE, etc.

Protect endpoints

This option is disabled by default. In order to enable it, you need to set “Protect endpoints enabled” to true.

This feature comes with 2 actions:
– Apply on All REST Endpoints
– Apply only on specific REST endpoints

When you choose Apply on All REST Endpoints, you will be able to whitelist some endpoints from your WordPress REST by adding them to the whitelist section.
For example, If you only want to allow users to access the wp/v2/posts endpoint without having to provide the JWT, you save in the whitelist section wp/v2/posts

When you choose Apply only on specific endpoints, you will have to add all the endpoints you want to be protected by JWT.

When an endpoint is protected, and you don’t provide a JWT, you will get the following response:

{
“success”:false,
“data”:{
“message”:”Your are not authorized to access this endpoint.”,
“errorCode”:403,
“type”:”simple-jwt-login-route-protect”
}
}

PHP

In order to easily integrate your app/site with simple-jwt-login, we have developed a composer package.

composer require nicumicle/simple-jwt-login-client-php

You can check the package page for more details and code examples.

Javascript

Also, there is a Javascript SDK that you can install with npm or yarn.

npm install “simple-jwt-login”

or

yarn add “simple-jwt-login”

Here’s how you install and activate the JWT-login plugin:

1. Download the Simple-JWT-login plugin.
2. Upload the .zip file in your WordPress plugin directory.
3. Activate the plugin from the “Plugins” menu in WordPress.

or

1. Go to the ‘Plugins’ menu in WordPress and click ‘Add New’
2. Search for ‘Simple JWT Login’ and select ‘Install Now’
3. Activate the plugin when prompted

Next steps:

• Go to “General section”

  • set “JWT Decryption key”. With this key, we will validate the JWT.
  • choose “JWT Decryption algorithm”.

• Go to “Login Settings”

  • please set “Allow Auto-login” to “yes”.
  • set parameter “Action” ( Login by WordPress User ID / User Email).
  • set the “JWT parameter key” with the key from your JWT where user email or user ID can be found in the decoded JWT.

After that, you can copy the sample URL from the top of the page ( Login Config section), replace the JWT string with your valid JWT, and you will be redirected to your WordPress and automatically logged in.

Also, if you don’t want to add the JWT in the URL, you can add it in the header of the request with the key ‘Authorization’.
Please note that the JWT that is set in the header overwrites the one from the URL.
