First of all, navigate to https://developers.facebook.com/apps/ as the plugin tells you to do.
When you see the screen of the Facebook for Developer site, click Register Now on the top right of the page to create a Facebook Developer account.
This site will ask you to register with your Facebook account. In the event, you have more than one Facebook account, just choose one. Then, press Next and fill in the password of your Facebook account if asked.
Next, just choose one option when it asks you which one is the best to describe to you. If you are not sure about this, select Other.
2.2. Create a Facebook app

To finish, press the Create App ID button.
2.3. Configure the new Facebook app

An interface as below will appear:
Fill in those fields with the missing information as follows:
- App Domain: Write your website’s domain there.
- Terms of Service: Fill in this box with the URL linked to your website’s terms of service page.
Here is an example of my website. I put these URLs at the footer of my web page. Now I just need to go there and copy their URLs then paste into required fields.
After completing all 3 fields above, press the Save Changes button under those fields.
In the same window, click on the cross (+) in the Products (+) menu on the left. Here we press the Set Up button in the Facebook Login box.
Now, the product named Facebook Login will show up in the Products (+) menu. Click on it then choose the Quickstart option. You will see 4 options here. Just choose the 3rd option – Web – as you are trying to integrate your Facebook Login with a website.
In the next screen, there will be a blank field named Site URL. Let’s fill it with your website URL. After that, click Save.

At the top of the current page, look at the grey Off button next to Status – In Development. Press it to make your app public.
Choose a category of your website in the upcoming popup. then press Confirm button.
The Off button now changes to On and has a green color. Furthermore, the Status also changes from In Development to be Live at the same time. That means your Facebook App has been activated.

A new window will appears right now and ask you to log in to your Facebook account. Log in with the account which you used to register the account in Facebook for Developer. Press Continue as … to complete the login process.
A notification from the plugin that The test was successful will be shown. That means your setting is done.
However, if the plugin shows you a notification is Work Fine – Disabled in the yellow box (as in the picture below), it means that the Facebook App has not been enabled on your website. Therefore, press the Enable button to allowed your Facebook App to be valid on your site. Then click Save Changes.
In the WordPress Admin Dashboard, go to Pages > Add New. There you will add a totally new page to your website with the title such as Facebook app login for web.

So now, your WordPress site has got a page for Facebook login already.
You may check if you have succeeded or not. Copy the permalink of the page you have created, log out of your current web account then paste the link into the navigation bar to get access to your new login page.
Your new login page will show up as a kind of below:
When you come back to log in your admin account, you will see that one more option to log in using Facebook account is added.
As you see, the default button has the text Continue with Facebook and has the classic blue color. If you want to modify it, do as follows:
On the admin dashboard, go to Settings > Nextend Social Login, then choose the Buttons tab.
There will be 3 fields which correspond with 3 buttons that Nextend Social Login plugin provides. Change the text in each field to edit the text on each button.

- Unlink Label: This label displays on the button when the user wants to unlink a Facebook account from your site.
- Default Button: If you satisfy with the default design of the button, leave this box blank. Otherwise, tick the box to customize the button as you want.
After finishing your adjustment, click Save Changes.
If you and any other user can not register a new account on your website using a Facebook account, recheck your setting for membership on your site.
In the admin dashboard, go to Settings > General. There will be two options named Membership and New User Default Role.
Be sure that the Anyone can register box in the Membership section is ticked.
Choose a suitable role for the new register in the New User Default Role field. For my site, I set it is Customer.
Scroll down and click Save Changes to save your settings.
Now anyone can use the Continue with Facebook button on your website’s login page to register his new account.
