Facebook login lets users sign in to a WordPress website using their Facebook account instead of creating yet another username and password.

And no, we are not alone in feeling this way. Det viser forskning fire ud af fem (86%) personer er generet af behovet for at oprette nye konti, når de registrerer sig på en hjemmeside. 

Hvad der er mere alarmerende fundet i den samme forskning er, at 9 ud af 10 personer (90%) indrømmer, at de har forladt et websted, hvis de har glemt deres adgangskode eller login-oplysninger, i stedet for at besvare sikkerhedsspørgsmål eller nulstille deres adgangskode!

Ways to Add Facebook Login on a WordPress Website

There are three common ways to add Facebook login to a WordPress website. The right approach depends on how much control you need and how comfortable you are with ongoing maintenance.

1. The most common option is using a social login plugin. This method handles authentication, permissions, and API changes for you. It is suitable for most WordPress websites.
2. Another option is manual integration using Facebook’s SDK. This approach requires custom development and direct handling of app credentials, redirect URLs, and user data.
3. Some websites also rely on third-party identity providers that sit between Facebook and WordPress. These services simplify setup but add an external dependency.

In this guide, the focus is on the plugin-based method using WP Social, which works well for most WordPress use cases.

Why Should You Add Facebook Login on Your WordPress Website?

Most people already have Facebook accounts. That is not the real reason Facebook login works.

At integrere knappen 'Log ind med Facebook' på dit WordPress-websted er et klogt træk af en række årsager. Når du lader brugerne logge ind på din WordPress-side med Facebook, slipper de for adgangskode træthed som de ellers ville gå igennem. 

Oven i det, da de besøgende ikke behøver at udfylde endnu et login/registreringsformular, kan de spare deres værdifulde tid til at investere i at udforske din hjemmeside mere. 

When users log in with Facebook, they do not need to remember passwords or fill out long registration forms. This saves time and makes the login process smoother, especially for first-time visitors.

However, Facebook login is not a universal solution.

In practice, we have seen Facebook login improve access on content-driven and community sites, while causing drop-offs on email-first or compliance-heavy setups.

While it improves convenience, it also introduces dependency on a third-party platform. That tradeoff matters and should be considered before enabling it on your site.

Men du undrer dig måske nu over de fordele, du kan høste ved at tilføje et Facebook-login til WordPress-websteder. Nå, jeg vil nu tale om nogle vigtige årsager til Facebook-integration på dit websted:

• You can get to know the full name of the users from Facebook. It can enable you to send personalized newsletters and updates.
• Mens mange brugere tilmelder sig websteder med falske e-mails, er de registrerede e-mails fra brugerne på Facebook mere tilbøjelige til at være ægte.
• Tilføjelse af et Facebook-login til dit websted vil også hjælpe dig med at få de besøgendes placering, køn og alder. Du kan forberede din marketingplan mere præcist med de personlige data.
• Tracking the “Likes” of the users, you can offer a more tailored service to them. Additionally, accessing their Facebook friend lists can enable you to recommend them the products or services their friends are using.

Recommendation:
Use Facebook login as an optional shortcut, not a replacement for email login. This keeps flexibility without dependency.

Before You Continue: Is Facebook Login Right for Your Site?

Before moving forward, it is important to decide whether Facebook login actually fits your website.

Facebook login works well if your site targets general users, communities, or content-based platforms where quick access matters more than strict user qualification.

However, if email ownership is critical to your business, or if your site operates under strict compliance requirements, relying too much on social login may create issues later.

If your audience values speed and convenience, continue with the setup.
If control and data ownership matter more, use Facebook login for WordPress carefully and always keep alternatives available.

Sådan tilføjes Facebook-login til WordPress-webstedet (trin-for-trin)

If you want to know how to integrate the Facebook login on your WordPress website seamlessly with a plugin, I am going to give you a step-by-step detailed guideline now using Wp Social. Follow the steps properly and add Facebook to WordPress for login.

Lad os gå videre: 

Step 1: Install a Facebook Login Plugin for WordPress​

To install the Facebook login plugin for WordPress:

● Log ind på administrationspanelområdet på dit WordPress-websted.

• Login to your Facebook account If you are logged out. 
• Click on the “Get Started” section to start creating your developer’s account. Follow the instructions step-by-step to complete your registration process for a Facebook developer account.

Trin 3: Opret en Facebook-app 

• After completing your registration as a developer, you’ll be redirected to the Facebook app creation page. Click on “Opret app” at gå videre

• At this step of app creation, set a meaningful App Name and Add contact email. After that, click on “Next”.

• You must select ‘Other’ as the use case here. Click on ‘Next’ when you are done.

Now, select Consumer and press the ‘Next’ button.

In this step, you can check the whole details again and press the ‘Next’ button.

After that, you may be required to log in to your Facebook account again.

Trin 4: Konfigurer Facebook-login

Finally, here is your App dashboard and

After the process mentioned above, you’ll be taken to the ‘Products’ page located under Dashboard. Click on the ‘+’. Find out ‘Facebook Login’ from the list and click on ‘Set Up’.

Go to Settings under the Facebook Login app. You have to enter Valid OAuth Redirect URIs under Client OAuth Settings.

To get the Valid OAuth Redirect URIs, you have to go to your WordPress admin area.

Navigate to WP Social ➔ Social Login ➔ Providers➔ Facebook➔ Click on the toggle button or Getting Started.

• You’ll now see a link to be used as Valid OAuth Redirect URIs. Copy it and go back to Facebook Login app settings to paste that on the ‘Valid OAuth Redirect URIs’ field.

• Now, go to the ‘Basic’ submenu under Settings. Copy the App ID and App Secret for using those in the Wp Social app. Fill up other fields and click on ‘Save Changes’ when you are done.

Important Setup Insight (Often Missed)

Many Facebook login setups appear to work but fail in real usage.

This usually happens because of small configuration issues that are easy to overlook. For example, a mismatched OAuth redirect URI or unnecessary permission requests can silently break the login process.

Always make sure that:

• Your Facebook app is set to Live mode
• The OAuth redirect URI matches exactly
• Only the required permissions are requested

A visible login button does not always mean the login flow is working correctly. Testing matters more than installation.

Trin 5: Brug dit app-id og apphemmelighed med Wp Social 

• Once you’ve completed creating an app on Facebook, go to the WP Social login from the WordPress dashboard. Navigate to Social Login ➔ Providers. Switch the left button below Facebook ‘ON’ and then click ‘Settings’.

Trin 6: Konfigurer WP Social Plugin's indstillinger

● Gå derefter til stilindstillingerne, vælg din yndlingsstil og klik på 'Gem ændringer' for at implementere dit valg.

How to Know Your Facebook Login Is Working

After completing the setup, do not stop at seeing the login button.

You should test whether:

• New users can log in and get WordPress accounts created
• Existing users can log in again without errors
• Facebook login works properly on mobile browsers
• Logout and re-login works as expected

When configured correctly, Facebook login usually results in faster first-time access and fewer abandoned registrations. If login numbers increase but engagement drops, placement and usage should be reviewed.

Det er alt. Du kan nu se Facebook-login præcis hvor du vil på din WordPress-hjemmeside med din yndlingsstil. Så du fik ideen til, hvordan du tilføjer Facebook til WordPress i et par enkle trin. Hvis du nu vil tilføje socialt login til dit websted, kan du det se dette indlæg.

Manual Facebook Login Integration (Advanced Method)

Facebook login can also be added manually without using a plugin. This approach is typically used when a site needs full control over the authentication flow.

Manual integration requires working directly with Facebook’s JavaScript or PHP SDK. You must configure the App ID and App Secret securely, set correct redirect URIs, and manage permission scopes such as public profile and email.

This method also requires ongoing maintenance. Facebook API changes, permission reviews, and security updates must be handled manually.

Because of this complexity, manual integration is generally recommended only for developers or highly customized WordPress setups.

Common Facebook Login Issues and Fixes

Facebook login on WordPress issues are often caused by configuration mismatches rather than plugin errors.

A redirect URI mismatch usually occurs when the callback URL in Facebook Developer settings does not exactly match the WordPress login URL.

If login works only for admins, the Facebook app may still be in development mode and not publicly available.

Some users may not receive an email address if the email permission is not approved or available on their Facebook account.

Login buttons may not appear if page caching or CDN settings block dynamic scripts.

Facebook login on WordPress also requires HTTPS. Sites without a valid SSL certificate may fail authentication.

Frequently Asked Questions (FAQ) on Login with Facebook on WordPress

Kan jeg bruge PHP til at tilføje Facebook til WordPress-webstedet?

Ja, hvis du har tilstrækkelig teknisk viden, kan du også gøre brug af PHP til at tilføje et Facebook-login til dit WordPress-websted. Det vil dog tage en god del tid, da du skal installere Facebook SDK til PHP i projektet.

Kan jeg offentliggøre Facebook-loginknappen på en hvilken som helst tilpasset WordPress-side?

Heldigvis ja! Wp Social tilbyder kortkoder, så du kan bruge Facebook-login-knappen, hvor du vil på dit WordPress-websted.

Is Facebook login still relevant today?

Yes, but it should be used selectively. It works best as a secondary login option rather than the primary one.

What happens if Facebook is blocked or down?

Users will not be able to log in with Facebook. That is why email or username-based login should always remain available.

Is Facebook login safe?

Yes, when configured correctly. However, you should request minimal permissions and clearly inform users about what data is being accessed.

Can the same Facebook App be used on multiple WordPress websites?

Yes. A single Facebook App can be used on multiple websites as long as all domains are added to the app settings and the redirect URIs are configured correctly.

What permissions are required for Facebook login?

At minimum, Facebook login requires access to the public profile. Email permission is commonly requested but may require review and is not guaranteed for all users.

Does Facebook login work with WooCommerce or membership plugins?

Yes. Facebook login works with WooCommerce and most membership plugins as long as user registration is enabled and the plugin supports standard WordPress authentication.

Afsluttende tanker

Facebook login can reduce friction. It can also create dependency. So, it is always highly recommended to use it intentionally.

However, here are some key points that you should keep in mind –

1. Keep email login available

So, choose based on your audience, not trends.

Hope that you’ll be successful in adding a Facebook login for WordPress. The exact plugin may change over time, but the decision factors and setup checks covered here remain the same.
