Auto Login with Cloudflare

I am testing this plugin, I think Jetpack's secure login feature can be replaced with this plugin, this means I can remove Jetpack after my testing is done.

Good job, thank you so much.

Great Auth plugin

Clean, simple, and precisely what it promises.

I just configured my complete setup using Cloudflare Access with auth via AzureAD and auto-login to wp-admin. This plugin is gold!

Combined with the Authenticated Origin Pulls feature of CF, this is seamlessly intertwined enterprise-level security for free.

I love this! Thank you!

Super simple way to allow a single sign on to your Wordpress site when using Cloudflare Access.

<h3>Login User</h3>
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:
<ol>
<li>URL</li>
<li>Header</li>
<li>Cookie</li>
<li>Session</li>
</ol>
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:
<ul>
<li>Dashboard</li>
<li>Homepage</li>
<li>or any other custom Page ( this is mainly used for redirecting users to a landing page)</li>
</ul>
You can attach to your redirect a URL parameter <code>redirectUrl</code> 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 <code>Allow redirect to a specific URL</code>.
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: 
– <code>{{site_url}}</code> : Site URL 
– <code>{{user_id}}</code> : Logged in user ID 
– <code>{{user_email}}</code> : Logged in user email 
– <code>{{user_login}}</code> : Logged in username 
– <code>{{user_first_name}}</code> : User first name 
– <code>{{user_last_name}}</code> : User last name 
– <code>{{user_nicename}}</code> : 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:
<pre><code>http://yourdomain.com?param1={{user_id}}&param2={{user_login}}
</code></pre>
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.

<h3>Register Users</h3>
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 <code>user_meta</code> with a json. This will create user_meta for the new user.
<pre><code>{
 "meta_key":"meta_value",
 "meta_key2":"meta_value"
}
</code></pre>
These properties can be passed in the request when the new user is created.
<ul>
<li>email : (required) (string) The user email address.</li>
<li>password : (required) (string) The plain-text user password.</li>
<li>user_login : (string) The user’s login username.</li>

<li>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.</li>
<li>description : (string) The user’s biographical description.</li>
<li>rich_editing : (string) Whether to enable the rich-editor for the user. Accepts ‘true’ or ‘false’ as a string literal, not boolean. Default ‘true’.</li>

<h3>Delete User</h3>
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.
<h3>Reset Password</h3>
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.
<a href="https://simplejwtlogin.com/docs/delete-user/" rel="nofollow ugc">Read More</a> on our website.
<h3>Authentication</h3>
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(or username) and password ( or password_hash) and the response will look something like this:
<pre><code> {
 "success": true,
 "data": {
 "jwt": "NEW_GENERATED_JWT_HERE"
 }
 }
</code></pre>
If you want to add extra parameters in the JWT payload, just send the parameter <code>payload</code> on <code>/auth</code> 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 <code>/auth</code> generates.
If you want to get some details about a JWT, and validate that JWT, you can call <code>/auth/validate</code>. 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 <code>/auth/revoke</code> and send the <code>jwt</code> as a parameter.
The plugin auto-generates the example URL you might need to test these scenarios.

<h3>Auth codes</h3>
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

<h3>CORS</h3>
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.
<a href="https://simplejwtlogin.com/docs/cors/" rel="nofollow ugc">Read More</a> on our website.
<h3>Protect endpoints</h3>
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 <code>Apply on All REST Endpoints</code>, 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 <code>wp/v2/posts</code> endpoint without having to provide the JWT, you save in the whitelist section <code>wp/v2/posts</code>
When you choose <code>Apply only on specific endpoints</code>, 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:
<pre><code>{
 "success":false,
 "data":{
 "message":"Your are not authorized to access this endpoint.",
 "errorCode":403,
 "type":"simple-jwt-login-route-protect"
 }
}
</code></pre>
